Airplane air speed indicators ( the preferred term) are normally calibrated in Miles Per Hour ( statute) or Knots which is nautical MPH. In some European countries they may use Kilometers per hour. automobile and aircraft speedometers work on different principles and parts do not interchange, as it were. the question is silly, most Aircraft speed indicators are either in statute miles or Knots- Nautical miles-per hour. Kilometers per hour are not generally used.
There hasn't been up to time of answer an aircraft fly at or higher that the speed of light
to have a aeroplane fly you have to use its fans in its wings
Whenever he flies at that speed, his speed is exactly 90 meters per second. That's the same as 201.3 miles per hour, and 324km/h
Orville Wright was the first to fly an aeroplane.
Fly
9,000/320 = 28.125 seconds
= 48 m / 24.0 s = 2.0 m/s
Depends on the lane . Some very small planes fly at 80 knots minimum whilst the airliners are 130 minimum or stall speed

You fly an aeroplane; you don't drive it.
twice the speed of sound (1400 miles per hour or 2250 kilometers per hour)! ...
