Define Critical Field Length (CFL). (TO 1T-38C-1TO: A3-2)

Answer 10

The total runway length required to accelerate with both engines operating to the critical engine failure speed (CEFS), experience an engine failure, then either continue to accelerate to Single-Engine Takeoff Speed (SETOS) and takeoff, or stop in the same distance.

Question 11

Define Refusal Speed (RS). (TO 1T-38C-1TO: A3-2)

Answer 11

The maximum speed at which the aircraft is able to accelerate with both engines operating in MAX and either: Abort with Both Engines Operating (BEO) or abort with an Engine Failure (EF).

Question 12

What assumptions are made for Refusal Speed (RS)? (TO 1T-38C-1TO: A3-3)

Answer 12

1. 3-seconds to recognize and react to an event
2. During 3-second reaction time, engines are either both producing MAX thrust (BEO) or one engine is producing MAX and the other is windmilling (EF)
3. If the aircraft is in a three-point attitude and the airpeed is below 130KCAS, wheel brakes are gradually applied such that desired braking is reached in 2 seconds
4. If the aircraft has rotated, the 7.5o NH pitch is held until 120 KCAS. Wheel braking is not used during aerobrake.
5. Cautious braking is applied from 130-100 KCAS. Optimum braking is applied below 100 KCAS.

Answer 14

Two-Engine Takeoff Speed

Question 15

Define Critical Engine Failure Speed (CEFS). (TO 1T-38C-1TO: A3-4)

Answer 15

The speed to which the aircraft accelerates with both engines, experiences an engine failure and permit either acceleration to SETOS and takeoff or decelerate to a stop in the same distance.

Question 16

Define Decision Speed (DS). (TO 1T-38C-1TO: A3-4)

Answer 16

The minimum speed at which the aircraft is able to experience an instantaneous engine failure and still accelerate to SETOS and takeoff (approx. 700 feet from the start of rotation) in the remaining runway.

Question 17

Define Minimum Acceleration Check Speed (MACS). (TO 1T-38C-1TO: A3-5)

Answer 17

The minimum acceptable speed at the check distance with which takeoff should be continued

Question 18

Define Normal Acceleration Check Speed (NACS). (TO 1T-38C-1TO: A3-5)

Question 19

How is MACS calculated? (TO 1T-38C-1TO: A3-28)

Answer 19

Subtract 3 knots from NACS for each 1,000 feet of runway in excess of CFL, not to exceed 10 knots
