Aircraft performance

thumb|Landing of Hawker Sea Fury FB 10 Landing is the last part of a flight, where a flying animal, aircraft, or spacecraft returns to the ground. When the flying object returns to water, the process is called alighting, although it is commonly called "landing", "touchdown" or "splashdown" as well. A normal aircraft flight would include several parts of flight including taxi, takeoff, climb, cruise, descent and landing.

For space vehicles that launch vertically, this is known as liftoff.

aerodynamic efficiency of how far an aircraft can move forward without engine power for every meter it sinks

airplane wings capable of changing position to alter their geometry

distance a vehicle can travel

Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.
