TOLD

Question 1

Define takeoff distance

Answer 1

Distance in feet from brake release to main gear liftoff

Question 2

Define critical field length

Answer 2

Total runway length required to accelerate with both engines operating to critical engine failure speed, have an engine failure and either continue to SETOS (approx 700’ from start of rot at SETOS) or stop in same distance

Question 3

Define refusal speed

Answer 3

Max speed to which the aircraft is able to accel in MAX with both engines operating and abort. There is an RS-BEO and RS-EF (both engines operating and engine failure)

Question 4

Define SETOS

Answer 4

Speed at which the ac is able to climb, once clear of the ground effect, at a minimum of 100’/NM with gear down, flaps 60%

Question 5

Define critical engine failure speed (CEFS)

Answer 5

Speed to which the ac accelerates with both engines, experiences an engine fail and permits either accel to SETOS and takeoff or stop in same distance

Question 6

Define decision speed (DS)

Answer 6

Min speed at which the ac is able to experience instantaneous engine fail and still accel to SETOS and takeoff in the remaining runway

Question 7

Define rotation speed

Answer 7

The speed at which aft stick is initiated

Question 8

What are CFL assumptions?

Answer 8

Valid up to SETOS

Assumes no aerobrake

Question 9

What are RS assumptions?

Answer 9

3 s to recognize and pull throttles to idle
Wheel braking not used w aerobraking, applied when NW on grd in 2 s
Accel continues at MAX with either one windmilling or both still at MAX
Nosewheel stays off rwy until 120 kts then settles at 120 kts
Attitude of 7.5 deg NH held if rotated
During BEO both engines produce idle thrust; during EF one is windmilling
Aerobrake not assumed
Braking cautious 135 to 100, optimum at 100

Question 10

What are SETOS assumptions?

Answer 10

• Rotation is started at SETOS during single engine TO
• Min SETOS is 2-engine takeoff speed
• Accel to SETOS in 3 pt attitude
• Delaying rotation improves performance
• Best rate of climb with gear, flaps 60% is 200 kts at #12,800 220 kts with gr dn flaps up

Question 11

What are CEFS assumptions?

Answer 11

DS assumptions apply if accel to SETOS
RS assumptions apply if aborting
CEFS valid up to SETOS
Aerobrake not assumed

Question 12

What are DS assumptions?

Answer 12

• 3 sec delay to react, in which engines stay one MAX other windmilling
• if ac hits rotation speed during time, rotation attitude is set
• after 3 sec ac maintains or returns to a 3 point attitude to accel to SETOS w neutral stick

Question 13

Define NACS

Answer 13

Normal Accel Check Speed

Approximate speed an ac will reach at a predetermined distance down the runway

Question 14

What are NACS assumptions?

Answer 14

Normal accel

Check distance must be less than go/no-go speed

Question 15

Define MACS

Answer 15

Min Accel Check Speed

min acceptable speed at check distance with which TO continued

Question 16

What are MACS assumptions?

Answer 16

Allows for variation in technique, engine trim, throttle setting (3 T’s)
Subtract 3 kts from NACS for each 1000’ in excess of CFL, not to exceed 10 kts

Question 17

If you have a remote BAK-15 how does go/no-go work?

Answer 17

DS<=EF. EF is go/no-go.

DS>EF. TOS is go/no-go with OG approval and rated pilot on TO

Question 18

If you have a raisedBAK-15 how does go/no-go work?

Answer 18

DS<=EF, EF is go/no-go must be done by rated pilot if CFL w/in 1000’ of RL
DS>EF, SETOS is go/no-go but OG approval, rated pilot, delay rot until 155 kts, ensure NW liftoff by 174 kts

Question 19

If you have no BAK-15 how does go/no-go work?

Answer 19

DS<=BEO, go/no-go is BEO
DS>BEO, EF is go/no-go with OG approval and rated pilot
DS>EF, PROHIBITED TAKEOFF
