• “To act as PIC of an aircraft on an IFR flight plan, one must have logged (within the preceding 6 months):– 6 approaches– holding– intercepting and tracking navigation courses– or passed an IPC

Currency

3 approaches, navigation, holding

Need IPC

Aeronautical Decision Making

• D etect a change

• E stimate what is needed

• C hoose a successful outcome

• I dentify actions required

• D o the necessary

• E valuate

Hazardous attitudes

• Anti-authority

– rules and procedures are unnecessary

• Macho

– best pilot

• Impulsivity

– first action that comes to mind

Hazardous Attitudes

• Invulnerability

– bulletproof

• Resignation

– What’s the use?

Vestibular Disorientation

• Coriolis illusion(in turn move head)

• Graveyard spiral

• Leans

• Somatogravic illusion (acceleration =climb)

• Inversion illusion (climb to S&L= backwards)

Disorientation

• To prevent disorientation, one must rely on instruments, not body signals.

Hypoxia

• Hypoxic– high altitudes

• Hypemic– CO, anemia, smoking

• Stagnant– high G’s

• Histotoxic– alcohol, drugs

Hyperventilation

• Drowsiness

• Dizziness

Fundamental Skills

Cross Check Instrument Interpretation Aircraft Control

Fundamental Concepts

• Rigidity in Space - a wheel with a heavily weighted rim spun rapidly tends to remain fixed in the plane in which it is spinning

• Precession - when an outside force is applied the gyro responds as if the force had been applied at a point 900 further around in the direction of rotation

Instrument Checks

• With the power off, warning flags display OFF indications

• Inclinometer full of fluid and ball at lowest point

• Turn on master and listen for grinding noise in electric gyros

• After starting check ammeter

Instrument Checks

• Listen for noise from vacuum gyros

• If you think you hear noise, shut off the engine and listen to the gyros spin down

• It can take 5 minutes for the gyros to reach full operating speed

Instrument Checks

• While taxing out, the turn coordinator and heading indicator should indicate a turn in the correct direction

• The ball should swing to the outside in turns

• Align the heading indicator with the magnetic compass during runup and check again before takeoff

Magnetic Compass

• Errors– Variation - the angular difference between the

true and magnetic pole– Deviation - errors due to magnetic interference

with the metal components of the aircraft– Magnetic dip - the compass tries to point down

deep inside the earth

Pitot Static Instruments

• Airspeed Indicator

• Vertical Speed Indicator

• Altimeter

Types of Airspeeds• Indicated - displays the speed of your plane. It

is the basis for determining your aircraft performance

• Calibrated is indicated corrected for installation and instrument error

• Equivalent airspeed is calibrated airspeed corrected for adiabatic compressible flow at a particular altitude

Types of Airspeeds

• True Airspeed is the actual speed your airplane moves through the air. The calibrated airspeed corrected for density altitude

• Mach is the ratio of the aircraft’s true speed to the speed of sound

Types of Altitude

• Indicated - is what you read on the altimeter

• Pressure - is displayed when you have the altimeter set to 29.92. It is the vertical distance above the standard datum plane

• Density - pressure corrected for nonstandard temperature

Types of Altitude

• True - is the actual height of an object above mean sea level.

• Absolute - is the actual height of the aircraft above the earth’s surface

System Errors

• Can be caused by blockage of the pitot tube, static port or both

• Blockages can be caused by moisture, ice, dirt or even insects

• Use pitot tube cover when parked

• Use pitot heat when flying in visible moisture

Pitot Blockage

• Ram air inlet clogged, drain hole open pressure in line to airspeed indicator drops to zero, airspeed indicator indicates 0

• Ram air inlet clogged, drain hole clogged, air trapped in line, airspeed indicator does not react to changes in speed but altitude like an altimeter

Static Blockage

• Airspeed indicator will continue to react to changes in airspeed but they will not be accurate

• Altimeter will freeze in place

• VSI will freeze at zero

• Use alternate static source or break glass in VSI

VOR Receiver Checks VOT

– 180o TO, 360o FROM; +/- 4o VOR Ground Checkpoint

– Indicated radial; +/- 4o

VOR Airborne Checkpoint– Indicated radial; +/- 6o

– Centerline of airway; +/- 6o Dual VOR Check

– Within 4o

Using the VOR• Basic VOR Indicator

– each dot on CDI is 2o

– full scale deflection is 10o

– 1 deg in 60 nm is 1 nm– OBS

• Horizontal Situation Indicator HSI– incorporates HI, CDI, Glideslope– makes easier to scan– not reverse sensing except for using on BC

ADF Navigation

Ground based transmitter Low/medium frequency (AM) Non-directional beacon (NDB) Not line of sight No receiver checks No flags - listen to Morse code
