Front 1

Runway available

Back 1

runway length minus and unusable portion of runway such as the aircraft linup distance or barriers on or above runway.

Front 2

Runway length

Back 2

wunway length is the paved surface length excluding any overrun

Front 3

CEFS

Back 3

speed at which one engine can fail and the same distance is required to either continue to accelerate to lift-off speed, or abort and decelerate to a full stop

Front 4

CFL

Back 4

total length of the runway required to accelerate on all engines to critical engine failure speed, experience an engine failure, then continue to lift-off or stop. It is used during takeoff planning together with the climbout data to determine maximum gross weight for a safe takeoff and climbout. For a safe takeoff, the critical field length must be less than or equal to than the runway available

Front 5

take off factor

Back 5

%N1 settings adjusted for OAT and altitude and are presented on a different scale.

Front 6

T/O ground run

Back 6

runway distance normally obtained in service operation at zero wind at the mission-specified weight, P.A, thrust setting, ambient temp and appropriate T/O configuration using lift-off speed.

Front 7

Minimum control speed ground

Back 7

(88 KIAS) minimum controllable speed during take-off run, at which, when an engine is failed, it is possible to maintain directional control using only primary aerodynamic controls without deviating more than 25 feet laterally with all three wheels on the runway. The speed is established wiht the remaining engine at the TRT, the aircraft loaded at the most unfavorable weight and CoG, and the aircraft is trimmed for takeoff, without exceeding 180 lbs of rudder control force by the pilot with the rudder boost system operating. Conditions of crosswind and RCR my increase Vmcg.

Front 8

Minimum control speed air

Back 8

(89 KIAS) is the minimum controllable speed in the takeoff configuration out of ground effect with one engine inoperative and the remaining engine at TRT. Vmca is determined by the most critical combination of asymmetric thrust, lightweight, and aft center of gravity. The speed is established with the aircraft trimmed for takeoff, 5 degrees AOB into the ooperating engine and no more than 180 pounds of rudder control force by the pilot with the rudder boost system operating. Vmca is always less that takeoff speed and is not considered in takeoff planning.

Front 9

Refusal speed

Back 9

maximum allowable speed that can be attained, with normal acceleration, from which a stop may be completed with the available runway length.

Front 10

Max braking speed

Back 10

Max speed from which the aircraft can be brought to a stop without without exceeding the max brake energy limit (14.8)

Front 11

Takeoff Acceleration Check

Back 11

Speed for a given distance during takeoff ground roll. this speed can be checked against aircraft indicated speed at taht distance point to ensure that the takeoff is proceeding normalls. Compute Takeoff acceleration check whenever S1 is less that Vrot. Effects on wind, runway gradient, and RSC are included in the takeoff ground run. Use 100% of runway wind component for takeoff ground determination.

Front 12

S1

Back 12

The takeoff is committed at indicated airspeeds at or above S1. If an engine failure occures prior to obtaining S1, takeoff about capability is assured. In takeoff planning S1 is equal to or greater than the higher of ground minimum control speed, or CEFS. However, S1 must not be higher than the lowest of refusal speed, rotation speed, or maximum braking speed. If it is higher, the takeoff weight must be reduced untill this requirement is met.

Front 13

Vrot

Back 13

speed at which the aircraft attitude is increased from ground run attitude to lift-off attitude. This speed is greater than ground minimum control speed.

Front 14

lift-off

Back 14

moment at which the main gear lift off runway

Front 15

lift-off speed

Back 15

speed at which lift-off occurs

Front 16

takeoff flare

Back 16

ground distance covered between liftoff and the 50 ft obstacle height.

Front 17

takeoff speed

Back 17

speed which permits attaining the obstacle climb out speed at or before reaching the 50 ft obstacle height above runway.

Front 18

climbout speed

Back 18

scheduled single-engine climbout speed and should be obtained at or prior to reaching the 50 ft obstacle height. Two engine climbout is Vco + 10

Front 19

climbout factor

Back 19

variable used to determine takeoff/ climb performance and obstacle clearance. Minimum climbout factor for all takeoffs is 2.5

Front 20

minimum runway length

Front 21

min runway takeoff length

Back 21

6000 ft, critical feild length or distance to reach reference zero, whichever is greater.
