Hi all,
Today I was flying a B737-800 with the Auto Speed Brake System INOP. We applied the procedures described in the MEL but couldn't understand the following point A.
(O)OPERATIONS
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
Point B is logical because we manually have to raise the speedbrake on landing, this requires time so we have to cater for more landing distance required.
Point A I don't understand, because if we do an RTO the speedbrake already has to be raised manually in accordance with Boeing procedures. So why are we more limited on the Takeoff field length weight and brake energy limit weight?
Hope someone can point me in the right direction
