Definitions Flashcards
Accelerate stop distance
The distance required to accelerate the aircraft, recognize an engine
failure so that the first action to stop (brake application) is initiated at V1, and then bring the aircraft to a
full stop.
ACTUAL LANDING DISTANCE
Distance used in landing and braking to a complete stop (on a dry
runway) after crossing the runway threshold at 50 ft.
ASD Available
The runway plus stopway length declared available and
suitable for the acceleration and deceleration of an airplane aborting a takeoff.
Basic empty weight
Empty weight of the aircraft (includes required and optionally installed
equipment).
BASIC OPERATING WEIGHT
Sum of BEW and non-variable weight.
RAMP WEIGHT
Sum of ZFW and fuel loaded
Stopway
An area beyond the takeoff runway able to support the airplane during rejected
takeoff. It is designated by the airport authorities for use in decelerating the aircraft during rejected
takeoff.
TODA vs TORA
TODA includes Clearway
TORA is just the ground run distance available
Clearway
Area at end of runway cleared or suitable for use in lieu of runway to satisfy takeoff distance required
V1
Takeoff decision airspeed where pilot must take action to discontinue takeoff.
V2
Takeoff safety speed. Speed at 35ft above runway with lost engine rotating at Vr. Varies with gross weight
Vapp
Approach climb speed (1.3vs1) at flaps 15 and gear up
Venr
One engine inop en route climb speed
Wet runway
25% or more of required length within the width being used is visably damp or covered with water 1/8” or less
ZFW
Weight of aircraft and all is contents without fuel
