How far we have come:Wright Flyer – 1903
• 3 built• MTOW 430 kg (950 lbs)• Tire Pressure - N/A• One Pilot• No Pax• No Cargo• Design “Box” – 12.5m x 6.5m (A)
Airbus A380-800 – 2007
• 33 built (234 ordered (Aug/10))• MTOW 561,000 kg (1.23 MM lbs)• Tire Pressure – (218 psi)• Two Pilots• 525 to 850 Pax (3 class or 1)• 6,200 cu. ft.• Design “Box” – 80m x 72m (F)

Aircraft Tire Pressure Trends-More Rutting on Horizon?
A340-500/600, B747-400ER, A380-800F, B777-300ERB787, A350, B747-8 – all exceed current “X” upper limitof 1.50 MPa (217 psi)

Multiple Aircraft Ramp System (MARS)
IATA recommended aircraft stand configuration suited to mixes of Code E/C or Code F/C aircraft.Gaining usage at many new airports and airport upgrades and fits in with future Code E and C aircraft planned by major manufacturers
