Takeoff Thrust (N1, EPR) |
Aircraft dependent, but typically the static takeoff thrust setting for the given conditions |
V1 |
Takeoff decision speed; where the “go” or “stop” action occurs after deciding to fly or stop |
VR |
Rotate speed; where rotation is initiated |
V2 |
Takeoff safety speed; speed attained 35 ft above runway surface with one engine inoperative; also target climb speed after engine failure to maintain during 1st and 2nd segments until level-off altitude is reached |
VFTO |
Final takeoff speed; target climb speed during Final segment |
VENR |
Enroute speed, after clearing all obstacles |
TOFL |
Takeoff Field Length; takeoff distance per AFM definition for the aircraft |
Accelerate-Stop |
Accelerate-Stop distance; distance from brake release through V1 plus stopping distance from V1 through full stop during a rejected takeoff |
Accelerate-Go |
Accelerate-Go distance; distance from brake release through V1 plus the distance from V1 through rotation until 35 ft above runway surface is reached |
1st/2nd Gradient |
Climb gradient for the indicated climb segment |
Level-Off MSL / Level-Off Alt |
Target level -off altitude (in MSL) to clear all obstacles during a one-engine inoperative takeoff |
