Hello Members,

I hope you enjoyed your Christmas celebrations and managed to recharge your batteries

during the holidays. Another year has slipped by and an exciting New Year is upon us.

In the coming months the Club will achieve its CASA Part 142 accreditation. This will be achieved due to the hard work and dedication of our staff and in particular, our Head of Operations, Trevor Jones. It has taken a number of years of hard work and a substantial financial investment, to achieve this milestone. This will be a major achievement for the Club, setting us apart from other organisations at Jandakot, and giving us the very exclusive ability to offer integrated 150 hour Commercial Pilot’s Licence courses. Together with our ability as an RTO to offer GST-free courses, we are well-placed to maintain a strong, competitive position in the training market at Jandakot.

Of course, commercial training is only part of what the Club offers. Racwa is the best flying club in the west, with our own facilities and aircraft, as well as social and flying events for members. Being a member of such a great club enables you to share your joy of flying with like minded enthusiasts, and brings a social element to flying that only a club like ours can offer. We had a very good turn-out at the recent Christmas function, organised by Steve Wilson. It was great to see so many of you supporting the Club at this event.

Over the years we have had many exceptional Club Captains who have managed the flying and social events at the Club. Recently our Club Captain Craig Hensley stepped back after 6 years in the role, and we are very grateful for Craig’s hard work and dedication over the years. We welcomed Russell Philip into the position. You can rest assured that we won’t miss a beat, and we are planning one or two new activities for the coming year to complement our traditional events. I hope you will join us.

The Club is also here to support your flying training needs, such as your AFRs and endorsements. We encourage our members to continuously improve,

Onwards andUpwards

and one way to do this is to challenge yourself with a new qualification such as a tailwheel endorsement, formation endorsement or aerobatics endorsement. Perhaps you might like to step up to flying a twin-engined aircraft, or flying in instrument conditions with an IFR rating. If a modern two-seater light sports aircraft appeals to you, the new Sling 2 at Murrayfield might be just your cup of tea. The Sling is “on trial” and we hope it proves to be a great success. As with the other options the Club provides for members, we judge the success of a venture on the participation rate. I would encourage you to participate by trying the new aircraft, if you would like to see this venture succeed. To encourage utilisation we have offered a 3 hour conversion package at a low introductory rate. The package includes handling notes, ground instruction and flying time of 1.5 hours. To make the new aircraft even more attractive, you can also buy an initial discounted bulk flight package of 3 hours. Simply contact Operations to make a booking. More details can be found in this edition. The Sling will be based at Murrayfield, partly due to the greater accessibility of unleaded petrol there. Murrayfield is just a short drive south on the freeway. Speaking of Murrayfield – sincere thanks to Michael Chlopek for his long tenure as Instructor in Charge. Michael has changed to part-time, and we welcome John Crisp as Instructor in Charge at Murrayfield.

After the long, cold, wet winter of 2016, we have been making hay while the sun shines. Summer is of course, the busiest period in the calendar, and this summer is no exception. In mid-January the planets will align with heavy WAAC training and Air Force Cadets, so please be sure to book ahead to avoid disappointment. We have an exciting year to look forward to, and I hope to see you at the Club very soon.

Member Jim Dowell recently attended a comprehensive four day course in Las Vegas for pilots of twin engine Cessna aircraft. The course covered a

variety of topics such as accident investigations, corrosion, airframe, engines, propeller care, electrical and fuel systems, undercarriage, ignition and oil systems. Jim has kindly written a detailed report for members which can be found on our website. Conclusions and Key Points1. A Twin Cessna Fliers member made an informal study

which showed that 38% of all accidents had Systems Failure as their origin (including not maintaining/operating as per design). This is strangely reassuring to this engineer but rather rusty pilot, as I like studying systems.

2. Corrosion is inevitable and will inevitably cost more each year to control. It is a race to see which corrodes into oblivion first – the last Twin Cessna or the last Twin Cessna pilot.

3. In Perth, we live in an environment highly-corrosive to aircraft – it is a part of the warmth, sun and sea lifestyle. At least we don’t have to bother with much ice or birds that think plane cavities should be their new family home.

4. The first test flight of a Cessna 340 ended up killing Cessna’s test pilot. The cause was the little bolt attaching the trim tab to the elevator working free, which caused the elevator to flutter then jam. This led to an inverted flat spin. The littlest bits on a plane can cause the worst accidents. Inspect them carefully on each pre-flight.

5. Electrical systems may not have many moving parts, but like aged nerves and veins in 50+ yr old pilots,

Cessna Twins

brittle wiring is expensive and painful to replace, but it must be done.

6. Mechanical landing gear is costly to test but (relatively) easy to fix. Hydraulic landing gear is easy to test but (extremely) expensive to fix. Make your choice and spin the wheel. This is Las Vegas.

7. Bent fenders on front wheels and any dent on the steering stops of Twin Cessnas lead to bad gear problems. Of course, all gear problems are bad.

8. Learn how to lubricate properly, be it wheel bearings, turbochargers, bolts, cables, or mechanics. You’ll be a much happier, richer, and safer pilot.

9. Always use full power and max richness when taking off with turbo Twin Cessnas. This prevents leaner mixtures causing detonation or overheating – and makes take-offs more fun.

10. After annual/100 hr inspections, new engine installs or whenever anything on the engine is changed, do a series of test flights to record all sorts of engine parameter data. Not only does this provide a valuable source of “baseline” data for when there is a problem, but it also justifies more flying.

11. In discussions with the other pilots during meals, it became apparent that the rigour and consistency of training we experience at RACWA is closer to what US

military pilots undergo than what generally occurs at civilian US airports. Respect is due to Trevor, Amy, and the

RACWA managers who drag their students up the competency path. It makes for better aviators and is ultimately worth the pain and cost!In 1975, a hapless Aussie exchange student arrived in Denver 2 days after I gained my private licence. She was my first passenger. She only remembers trying to avoid getting sick in a claustrophobic, hot C-150, but it must not have been too bad. We have been married for 35 years now, and she is my biggest source of encouragement to get another Cessna Twin. I suggest that it is better to get the aviation bug first and then pick a life partner who is sympathetic to the aviation bug vs the other way around. I timed that right by 2 days. PS She no longer gets sick when we fly.

The introduction of a light sport aircraft (LSA) at Murrayfield is an example of the club’s ongoing investigation into fleet selection for our future. A

LSA is something new for the club and time will tell if this is an appropriate aircraft for our needs. Given that GA is declining, whilst the LSA market is growing, it is hoped that the Sling will result in a growth in our membership numbers.The Sling was introduced in Australia in 2013 and to date, 45 have been sold. The aircraft was certified in 2009 and over 240 have been sold worldwide. 10 Slings are currently operating in flying schools in Australia, recording impressive utilisation.According to the manufacturers, the Sling is the only LSA aircraft to have flown twice around the world, including a

27 hour flight across the Indian Ocean from South America to South Africa in a Sling 4 (6,222 kms).The Sling 2 has an endurance of over 6 hours. The view from the cockpit has to be experienced. The seats are also very comfortable. Members who have not experienced a joystick need not worry, there is no difference between the conventional Cessna yoke and the Sling joystick. Because the Sling 2 is in the LSA category, it is limited to 600 MAUW, despite being designed for 700 MAUW. It is currently being certified in Europe at the increased weight.Flying the Sling will give pilots the opportunity to experience the Garmin 3X touch screen. While it is easy to use, the range of information that can be obtained is very comprehensive. The aircraft is fitted with most of the standard instruments to give pilots the option of using glass or instruments that they are more familiar with.There is no denying that a LSA aircraft needs a lot more tender loving care than a Cessna 152. Pilots need to be careful when getting in and out of the aircraft. Using the seat for stability is an absolute no-no. This will all be explained in during the conversion process. The club will be adding the Sling to aircraft that can use Rottnest Airport at no cost to the pilot.

Students from both the college and TAFE combined to let off some steam with their instructors. The importance of letting one's hair down in the very

disciplined environment of pilot training is essential. The College will be organising a social outing at least twice a year in future.Chief ground instructor Andy Wood using open palms to achieve the winning shot.. (below)Amandeep Singh learns that he should keep both eyes on the ball (bottom).

After weeks of planning, the Murrayfield Open Day was held on 3rd December. Michael Chlopek had orchestrated the event with military precision. This proved to be very fortunate as Michael and his family

were confined to their beds as they had been struck down by a very nasty virus.Using Michael’s map and planning schedule, Brendan Swale marshalled the many helpers to make sure everything went according to plan. Signs were put out on Lakes Road, the jumping castle inflated and stalls erected according to the grand plan.The C152s were kept busy with trial flights, as was Tim Berryman in the Tiger Moth. The recently arrived Sling 2 received a lot of attention, as did other static displays such as a Cirrus and a Decathlon. The warbirds conducted some flypasts in their Nanchangs. John Ridgway was in his familiar position brandishing tongs in front of the BBQ providing food for onlookers. The day was cut short by adverse weather blowing in from the coast, but a good time was had by all. The objective of the day was to put Murrayfield airport on the map, and this objective was definitely met.A big thank you to Michael for organising the event, Brendan for stepping in and all the volunteers who helped make the day such a success.

Club Captain's CornerSquadron RAAF based at RAF Waddington in Lincolnshire. After the war Norman flew some flights repatriating POWs to the UK before leaving the RAAF and returning to civilian life.We set out for Jandakot for the flight. Unfortunately a weather band arrived at the same time we did. So, after squeezing Norman into a Tiger Moth, in which he learned to fly all those decades ago, the rest of us adjourned to the roof and bar to watch and drown our sorrows. On his return Norman joined us in the bar, where his daughter Kathy regaled us with some tales of Norman’s flying. December 11th saw seven competitors working on a low-level spot landing at Murrayfield. The day was won by Craig Hensley. The excitement for the day was provided by a WAAC student in a Mooney who had a close encounter with an emu while landing on runway 23 at YMUL. By the time this comes out our Christmas 2 for 1 Competition at Jandakot will be done and dusted and I will update you with the results in my next column.On January 26th, we’ll hold our usual Australia Day activities. Keep your eyes peeled for more details on the noticeboards. 29th January will see a Right Hand Seat circuit at Jandakot. We look forward to seeing you there – come along and see if you can fly as well from the right (or is that wrong) side of the aeroplane.In February, the flying committee are planning a fly-in to Jurien Bay for the weekend of 18-19. It will probably take the form of a mini Air Trial in each direction.

Book your aeroplanes and accommodation early and round up your passengers. I’ll sign off trusting that you have all had a Merry Christmas and a Happy New year and look forward to seeing you in 2017.Regards

Russell Philip, Club Captain

Mid-December sees the calendar roll over to the

time to generate another set of ramblings for the January Tarmac Topics and to bring you up to date with what has been happening at the club, at least from a social flying perspective, and what will/might/could

happen going forward.November/ December has been a pretty busy month for the club.On November 27th , we had a Rudder Circuit at Jandakot. On passing through 300 feet our trusty fleet of 152s all mysteriously suffered jammed ailerons. Oh well, secondary effects of controls means that we can still turn. A gentle application of rudder to start a turn and curiously our wings follow suit - around we go. As we come up to 90o - apply opposite rudder and we are back to wings level and not turning. Level off and repeat, until we are lined up on final, when passing back through 300 feet our ailerons inexplicably begin to work again – it must have something to do with the deck angle. Proving that I haven’t been listening to Craig’s lessons on score improvement - this competition was won by Jim DiMenna, with yours truly second and Rob van Hamersveld in third place.December 3rd saw us attempt our annual Dambusters Memorial Flight. A briefing was held under the wing of the RAAFA Museum Lancaster. We were joined by Norman Smith, a 93 year old former Lancaster pilot. The museum Manager graciously took Norman and his guests on a tour of the Lancaster while we briefed the flight. Norman served in 463

Our W.A. Safari

After a long time of planning our dream became reality. On September 1, 2016 we (Cornelia and Uwe) and VH-EEP departed on a WA air safari. We were fortunate to rent the C172 from

the RACWA in Jandakot, where we received all the support to plan an undertaking like this while living in a small village in the south of Germany near Karlsruhe.It was a great moment when I passed the flight review and took the key, the tools, the tie downs, the oil, the BP-Card and everything we could possibly need on our trip as well as the helpful advice and all good wishes from the staff. Our route took us up the coast to Broome and Derby, along the southern part of the Kimberleys all the way to Kununurra and back via Port Hedland, Newman, Paraburdoo (close to Karijini National Park) and Kalgoorlie. After 26 days, 53.6h VDO, 5100nm and 1600 litres of Avgas - we landed safely at YPJT. It is impossible for us to describe, in a few words, the exceptional beauty of the West Australian landscape. But if we had to compile a list of places we enjoyed most viewing from above, the Buccaneer Archipelago (north of Derby), the area around Wyndham, Lake Argyle, the Bungle Bungle Range in Purnululu National Park and Shark Bay would surely be on it.Finding a routing suitable for a time frame of four weeks turned out to be surprisingly simple. Given the places we wanted to visit and the limited number of airfields where avgas is available in WA, there weren’t too many options that suited our needs and kept us close enough to highways, railroads or the beach (just in case ...).From the tourist perspective we especially remember meeting nice people, watching animals, marveling at the fascinating landscape and departing at sunrise to our next destination. Also renting a 4WD to visit and stay in some small country town out in the nowhere and having a beer at the local hotel was great for us – and even greater if neither the pub nor the town has been mentioned in any of our travel guides. As a pilot I definitely enjoyed the freedom of flying. Once we left the busy airspace of Perth everything turned out to be quite easy. Flight planning in the evening, the morning preflight check of OUR plane (yes - it is yours for the time you rented it – at least it feels like it!), navigating and approaches to non-towered aerodromes while communicating with QANTAS and friends were all part of the fun. And after a challenging landing, the refueling and the tie down ritual helped to get the adrenalin out of the blood. Well, having a pilot licence is not so bad at all!We would like to thank all the people at RACWA who helped us to realise our dream and many happy landings to all of you!

Summer is upon us again, and it is at this time of year when dehydration and heat exhaustion can set in whilst working and flying in hot and humid conditions.

If an aircraft is left in the sun it will ‘soak’ up the heat and this will affect you. Dehydration -Did you know that 60% of our body weight is made up of water. Our bodies cool through the evaporation of sweat. But to allow this we need a constant water supply, and if not received the body will use its own stores of water to produce sweat. Dehydration will set in quite quickly if we don’t replace the fluids in our body, while it is trying to keep your body temperature at 33 degrees or below. At this sort of temperature, our body needs at least 4 litres of water per day, and that’s without any exercise or exertion! Symptoms - The symptoms of mild dehydration are: 4 Increased thirst. 4 Dry mouth and sticky saliva. 4 Reduced urine output with dark yellow urine. 4 Light-headedness (especially when standing) that is relieved by lying down.

4 Headache and possible dizziness 4 Pale, clammy skin 4 Decreased urination, or half the number of urinations in 24 hours.

4 Muscle cramps Your fluid intake should be spread throughout the day - don't wait until you feel thirsty, as it will be too late by then - you are already dehydrated. We have said before that

Effects of Heatan indication of whether you are drinking enough is the colour of your pee (urine). Once it is darker than a pale straw colour you should drink at least 250ml of fluid every 30 minutes until you see an improvement. Prevention - To prevent dehydration, you should hydrate early – i.e. before you start to feel thirsty. When working and flying in hot climate conditions, you need to: • Ensure you start the day with a good breakfast • Drink 1 cup (250mls) of water every ½ hour (20 Cups =

5Lts) • Drinkwaterorsportsdrinksonly(notfizzydrinks)• Increasefluidintakeifyoururineisdarkincolour• Find a cool or shady area to allow you to cool down

every couple of hours. This will help prevent the cumulative effects of heat exposure

Remember - it doesn't have to be a really hot day to feel the effects of dehydration. Part of our job as Pilot in Command is to maintain good health and the ability of good decision making.

Comps are a great

way of not only

maintaining currency, but also practising just for fun, and

meeting old, and making new, friends. Everyone is a winner at the competitions - so much to learn, practice, and enjoy - just look at the smiles afterwards.

A Warm Welcome to our New Members

When David was

asked why WAAC? He simply answered with “I wanted an organisation that would provide me with the best

chance in terms of industry, training and experience.”David Schneiker began studies with the club at the start of 2016 and 12 months later he is walking out with a Commercial Pilot's Licence (CPL). David said he always had a passion for flying and first experienced the joy of flight at age 15, however he decided to take a different career path that led him to owning a motorbike shop.In January, David thought it was time for a change, put

aside working full time and decided to throw himself into living out his childhood dream of being a pilot. Like many other students, David indicated the financial struggles of studying full time placed a toll on him during the year. Reflecting back, he says the struggle was worthwhile in achieving the goal.During his training, David together with Steve Parker and Milos Dragic organised an "hour building" trip where they travelled from Jandakot to Broome and back again. In total, they shared 30 hours flight time, and gave him a taste for what the future could be like flying alongside larger aircraft. David stated the hardest aspect of training was the intensity of the scenario based trading in the CPL Flight Training phase - he said “this training really pushes you, it makes you think outside the box and consider every alternative." David’s next challenge is tackling the instructor course.Congratulations David Schneiker on being the first of class A16 to achieve a CPL.

Why WAAC??

Are you looking to work for QANTAS, but worried about whether your maths will fit the bill??? Look no further and come to the Maths course we run. Just call

attended our last meeting for 2016. Thankfully, we catered well because everyone got a Christmas pudding and custard. John

Morrison brought along his 1.4 meter wingspan flying model of a Catalina and was lucky enough to win the free raffle for a flight in a Tiger Moth.Brian Hernan told us about Clayton Hutton, the mastermind behind Britain’s development of escape aids for downed airmen. Maps and compasses were produced to help them evade capture or escape from captivity and navigate to safe territory. Maps were printed on silk and compasses were disguised in tunic and shirt buttons. Some blankets could be made into suits and board games contained a variety of aids.John Wager spoke about his encounters with the Catalina aircraft. He witnessed the first to leave to fly the non-stop

Old Fliers Group5,632km leg to Ceylon. These were the “Double Sunrise” flights that were vital in maintaining communication during WW2. John reminded us that Churchill quoted that had Germany and Japan “closed the ring” then the future would have been bleak. One Canadian airman, Sq Ldr L Birchell, in a Catalina prevented that from happening.Our next meeting will be on Friday 27th of January. We wish all a safe and happy festive season. Our talks can be seen on our web site or YouTube Channel.

Sitting on a hot seat in sweltering conditions is one of the misfortunes of flying in summer. The 172 and M20J fleet have covers for the front windscreen to

minimise this situation. These covers have a dual purpose: to protect the aircraft interior and to prevent the pilot from sitting on a very hot seat.Windscreen covers are used for a few months each year. Pilots who learnt to fly in the cooler months do not always appreciate the necessity of using the covers after a flight.At the conclusion of each flight, pilots are required to demonstrate good airmanship and attach the windscreen

cover to the aircraft. Ask for help if you cannot reach the top press-studs. If the windscreen is covered with bugs, obtain a cleaning bottle and rags from Operations to clean the windscreen before attaching the cover. A cardinal sin is to allow the cover to touch the ground, as any tiny stone will damage a windscreen in less than an hour. The replacement cost for a windscreen, including labour, is almost $2,000 and this doesn't include the cost of an aircraft being grounded for that time. All pilots are requested to ensure they exercise appropriate diligence when attaching the cover.

Bar Staff Wanted - We need YOUR help to keep the bar openAn integral part of the club social scene is the

operation of the bar which is staffed solely by volunteers from within the club. We currently have a small core of people (you know who you are and you have my thanks) ably led by John Ridgway but more assistance is needed to ensure this group is not overwhelmed.Come and support YOUR CLUB – Volunteer to serve behind the bar – I guarantee you will meet a bunch of interesting people, get to hear plenty of stories (some of which might even be true), and learn things that you never dreamed you needed to know. If we can double the number of volunteers each one will only need to serve every two months or so.The bar is generally open on Friday afternoons from about 3.30 for the end of week social get together between Club staff, students, members, and visitors from the other operations around the strip. The night usually wraps up by

about 7:30. It is not uncommon to have 30 or 40 people present. Additionally the bar is opened on an ad-hoc basis after competitions and other eventsProfits from the bar help to fund our fly-ins and other social events throughout the year, provide funds for the miscellaneous expenses associated with running the club competitions, and in December assisted in providing a Tiger Moth flight for Norman Smith, one of the last surviving Lancaster pilots from World War Two, who attended our Dam Busters commemorative flight and shared some of his experiences with us.Without the bar we will have difficulty in continuing some of these activities that are an essential part of club flying. Come along and do your bit.Send your contact details to dcurrey@royalaeroclubwa.com.au – David will then let you know when you are rostered on.

Here's some interesting

information about the Cessna 152 - the

mainstay of our aircraft here at Racwa.DevelopmentFirst delivered in 1977, the 152 modernised the proven Cessna 150 design. It competed with the new Beechcraft Skipper and Piper Tomahawk and aimed to improve useful load with a maximum takeoff weight of 757kg, decrease internal and external noise levels and run better on the newly introduced 100LL fuel.As with the 150, most 152s were built at the Cessna factory in Wichita, Kansas, while some were built by Reims Aviation of France and given the designation F152/FA152.Cessna ended production of all their light aircraft in 1985 with 7,584 Cessna 152s worldwide (including A152 and FA152 aerobatic variants).The C152's successor was the Model 162 Skycatcher, built between 2007 and 2013.PowerplantAll Cessna 152s had a Lycoming O-235 engine which had more power than the Cessna 150, and was more compatible with the newer 100LL low lead fuel.152s made between 1977 and 1982 had Lycoming O-235-L2C engines producing 110hp at 2550 rpm but this engine suffered some lead-fouling problems and was replaced by the 108hp O-235-N2C with a different piston design and a redesigned combustion chamber to reduce this problem. AirframeA mainly metal construction, primarily 2024-T3 aluminum alloy with riveted skin, and components such as wingtips and fairings made from glass-reinforced plastic. The fuselage is a semi-monocoque with vertical bulkheads and frames joined by longerons running the length of the fuselage. The wings are a strut-braced design and have a 1o dihedral angle. The tapered (outboard) portion of each wing has 1o of washout (the chord of the tip section has 1o lower angle of attack than the chord at the end of the constant-width section) - allowing greater aileron effectiveness during stalls.It is equipped with differential ailerons moving 20o upwards and 15o downwards. It has single-slotted flaps or Fowler flaps which are electrically operated to a maximum of 30o. The rudder can move 23o either side and is fitted with a ground-adjustable trim tab. The elevators move through 25o up and 18o down. An adjustable trim tab is on the right elevator and controlled by a small wheel in the center of the control console. The trim tab moves 10o up and 20o down relative to the elevator chordline.Dual controls are available as optional equipment on the Cessna 152 and almost all have this option installed.Landing gearThe 152 has a fixed tricycle landing gear - the main gear has tubular steel legs surrounded by a full-length fairing with a step for access to the cabin and a 2.3m wheelbase.

Did You Know - Cessna 152

The nosewheel is connected to the engine mount with an oleo strut to dampen and absorb normal operating loads. It is steerable 8o either side of neutral, can castor under differential braking up to 30o and is connected to the rudder pedals through a spring linkage.The braking system consists of single disc brake assemblies fitted to the main gear and operated by a hydraulic system. Brakes are operated by pushing on the top part of the rudder pedals. It is possible to use differential braking when taxiing allowing very tight turns if necessary. The 152 is also fitted with a parking brake system.The standard tires used are 600 X 6 on the main gear and 500 X 5 on the nosewheel.ModificationsThe 'Texas Taildragger' involves strengthening the fuselage for the main gear being moved further forward, removing the nosewheel and strengthening the tail area for the tailwheel. This greatly improves short field performance and is claimed to give up to a 10kt cruise speed increase.The wings can be modified using a number of STOL (Short Take Off and Landing) modification kits, some improving high speed/cruise performance but most concentrating on STOL performance. They involve fitting a more cambered leading edge cuff to increase the maximum coefficient of lift, fitting fences at the aileron/flap intersection and fitting drooped wingtips. Landings are much shorter, while takeoff performance is also improved.Engine power can be increased, but the time between overhauls may also be reduced.Other popular modifications include: 4 Flap gap seals to reduce drag and increase climb rate 4 Different wingtips, some of which claim various cruise speed increases and stall speed reductions.

4 Mogas Supplementary Type Certificate (STC), which permits the use of car fuel instead of aviation fuel.

4 Auxiliary fuel tanks for greater range. 4 Door catches to replace the factory ones that often fail in service.

4 Belly fuel drain valves to drain fuel from the lowest point in the fuel system.

Variants152 - Two-seat touring aircraft with a fixed tricycle landing gear and a 110hp Lycoming O-235-L2C piston engine - 6628 built. Available with many avionic options - a 152 II has an enhanced package of avionics and trim features. The 152 II with Nav Pac included more avionics for IFR use. The 152T was a standard option package for use by flying schools, the "T" indicating "trainer" and not a sub-model.A152 Aerobat - Two-seat aerobatic-capable aircraft, 315 built.

Christmas BubblesStaff members climbed into bubble suits for the annual

staff Christmas party. No quarter was given as staff member pitted against staff member with no respect given

for seniority. Indeed, the younger instructors carried the day, emerging the victors.After a number of games of football, the bubble suits were severely tested with attempts to build bubble stacks, tossing an instructor in a bubble suit into a pile of bubble suits to see who would bounce the most and finishing off with four persons in bubble suits charging into each other to make a spectacular quadruple bounce.After the event, staff enjoyed a meal at Muzz Buzz and a drink or two at the bar. Thanks to all staff members for organising the event, especially Kovi and Brendan for selecting the bubble suit activity, and to Muzz Buzz for providing the dessert as a present to all staff.
