Question 21

Thrust reverser limits

Answer 21

During landing, max reverse prohibited below 75 KIAS and reverse idle should be achieved by 60 KIAS

Question 22

Engine wind limit.
> 30 degrees
< 5 knots

Answer 22

No limitations - TOGA thrust may be applied before brake release but must be set by 60 KIAS

Question 23

Engine wind limit.
> 30 degrees
Between 5 and 30 knots

Answer 23

A maximum of 75 % N1 may be applied before brakes release, then set TOGA thrust by 60 KIAS

Question 24

Engine wind limit.
> 30 degrees
> 30 knots

Answer 24

Only idle/taxi thrust may be applied be for brakes release, then set TOGA thrust by 60 KIAS

Question 25

Engine wind limitation.
<= 30 degrees
Wind speed unlimited

Answer 25

No limitations - TOGA thrust may be set before brakes release, but must be set by 60 KIAS

Question 26

If static/ standing performance is generated but engine wind limits prevent static/standing takeoff:

Answer 26

A) if auto wind using METAR unavailable, enter winds manually in ACARS

B) if ACARS and cFDP no comm; dispatch must manually insert winds in TLR data

Question 27

Flex thrust prohibited

Answer 27

1) anti-skid inop
2) contaminated runway
3) airplane has been de-iced
4) wing/cowl anti-ice in use
5) wind shear/downdraft warnings forecasted
6) engine cannot achieve full rated thrust
7) special departure demands TOGA
