AA1206 TOLD Flashcards
Define Takeoff Speed (TOS)
the speed at which the main gear lift off the runway
Define SETOS
The speed at which the aircraft is able to climb, once clear of ground effect, at a minimum of 100 feet per minute with gear down, flaps-60%.
During a single engine takeoff, rotation is initiated at…
SETOS at least
The minimum SETOS is…
two engine takeoff speed
Define Takeoff Distance (TOD)
The distance in feet from brake release to the point where the main gear lifts off the runway
Define Normal Acceleration Check Speed (NACS)
The speed an average T-38C should reach at a specified check distance down the runway
Define Minimum Acceleration Check Speed (MACS)
The minimum acceptable speed that any T-38C will accelerate to at a specific check distance down the runway
Define Refusal Speed - Both Engines Operating/Engine Failure (RS/BEO or RS/EF)
The maximum speed to which the aircraft is able to accelerate with both engines operating in MAX, and either: abort with Both Engines Operating or abort with an Engine Failure
Define Decision Speed
Minimum speed at which the aircraft is able to experience an instantaneous engine failure and still accelerate to SEOTS and takeoff (approximately 700 feet from start of rotation at SETOS) in the remaining runway
Define Critical Engine Failure Speed (CEFS)
The speed to which an aircraft can accelerate with both engines, lose an engine, and permit either acceleration to SETOS and takeoff or deceleration to a stop in the same distance.
The total distance needed to allow for CEFS is known as…
Critical Field Length (CFL)
Landing Distance is computed based on…
a 7.5 deg. Nose-high aerobraking attitude until reaching aerobrake speed, then lower the nose to the runway and gradually apply brakes so that the desired wheel-braking is reached within 2 seconds
Crosswind component ensures…
operations are within the crosswind limits for the planned takeoff or landing
Headwind component is used to…
compute most of the TOLD in the performance charts
Know when to Go/No-Go
GONOGO!
RCR number indicates
the degree of friction between the wheels and the runway surface
TOR distance
from brake release to where the main gear liftoff the runway at takeoff speed (TOS). TOS for a 12,700 lb T-38 is 164 KCAS
SETOS
speed which ensures a 100 ft/min climb out of ground effect on one engine with gear down and flaps 60%.
DS
minimum speed at which the aircraft can experience an instantaneous engine failure and still accelerate to SETOS and takeoff (approximately 350 feet from start of rotation at SETOS) in the remaining runway
RS
the maximum speed to which you can accelerate with both engines operating in MAX, and either: abort with both engines operating (BEO), or abort with an engine failure (EF).
RS Considerations
A 3-second pilot reaction time, aerodynamic braking (7.5°), and appropriate wheel braking (2 seconds to achieve cautious braking, and optimum braking below 100 kts) are all calculated into the abort.
CFL
distance from brake release for an aircraft to accelerate on two good engines to CEFS, experience an engine failure, and either continue to accelerate to SETOS and takeoff (approximately 350 feet from start of rotation at SETOS), or stop in the same distance.
NACS
the speed reached at a predetermined distance by a normal aircraft
MACS
minimum acceptable speed at a predetermined distance with which takeoff should be continued.
