Brake Disconnect Tool Installed:
Stopping distances will be increased with a brake deactivated. Adjust takeoff and landing performance in compliance with OM-B and Runway Performance Software (Finscap) data for 1 Brake Deactivated.
Brake Line Disconnected:
Adjust takeoff and landing performance in compliance with OM-B and Runway Performance Software (Finscap) data for 1 brake deactivated.
After takeoff, the landing gear must remain extended for a minimum of two minutes to allow the wheel to spin down prior to gear retraction. Takeoff climb and obstacle clearance performance will be limited by the requirement to keep the gear extended.
Adjust takeoff performance for landing gear extended based on OM-B Gear Down Appendix or Runway Performance Software (Finscap) data. In lieu of these adjustments, the following decrements can be applied to the climb and obstacle clearance limited weights to account for the 2 minute delay in gear retraction.
NOTE 1:Flaps 1 operation is not allowed.
NOTE 2:No operation with Improved Climb Performance.
1) Takeoff climb limit weight must be reduced by the following values.
Flap Position Weight Decrement
5 15,700 kg
15 13,000 kg
Flap Position Weight Decrement
20 10,200 kg
2) Takeoff obstacle clearance limited weight must be reduced by the following values assuming use of “extended 2nd segment” (5 minute thrust limit) procedures with MCT cleanup. All obstacles must be cleared by the height achieved at the end of “extended 2nd segment” climb:
Flap Position Weight Decrement
5 17,200 kg
15 14,300 kg
20 11,300 kg
