Reduce performance limited weights by the following:
A. Takeoff field length limit weight and brake energy limit weight: 1044kg
B. Landing field length limit weight based on auto speed brakes: 5897kg
So instead of having full travel of 56 deg. for spoilers 2,3,10,11 and 65 deg. for 4,5,8,9 you only have 19.5/24.5 deg.
I have a question; if the 'SPEEDBRAKE DO NOT ARM' light illuminates in flight and the QRH checklist is run, there is no reference to reduced performance on the runway. Is this because the CB has not been collared?
Or is there a chance ( depending on the failure) that runway performance may be reduced ?
Thanks for the good info,
Qanda
