How Much Does True Aispeed Change … WebDec 25, 2005 · Transition altitude at 18000ft is when aircraft flying at or above that altitude set their altimeter to 29.92. On the Boeing 777, below 31,000 feet, the airspeed is referenced by IAS (indicated airspeed) in knots or nautical miles per hour. Above 31,000 feet, the IAS automatically changes to Mach number in the airspeed indicators.
