rejected.
● VR. Answer: Rotation speed; the speed at which the pilot applies back pressure to lift the
nose.
● V2. Answer: Takeoff safety speed; minimum airspeed to maintain with one engine
inoperative after liftoff.
● Vref. Answer: Reference landing speed; typically 1.3 times stall speed in landing
configuration.
