Speed Brake

[Alphamale]

I may have missed it, but why is there not just a simple toggle for Speed Brake? One button assignment that when pushed once either extends or retracts it and the next push does the reciprocal. Why isn't this easier than what they have? From what I've read, the brake is either FULLY extended or FULLY retracted. There is no partial settings in the real plane

The speedbrake can be stopped at any position while being extended or retracted.

 

NATOPS 2.8.4.8.1:

The speedbrake switch is on the right throttle grip and has three unmarked positions.

 

Aft detent Extends the speedbrake as long as the switch is held aft. Springloaded to center detent.

 

Forward detent Retracts the speedbrake or maintains the speedbrake retracted and prevents creep.

 

Center detent Stops the speedbrake in any position. The speedbrake may slowly creep open.

2.8.4.8 Speedbrake. The speedbrake is mounted between the vertical stabilizers. It is controlled by

a throttle mounted switch using left 28 volt dc bus power. It is powered by the HYD 2A system.Airborne, when in the AUTO FLAPS UP mode, the speedbrake automatically retracts above 6.0 g or

above 28° AOA and, when not in the auto flaps up mode, below 250 knots. For aircraft 161702 AND

UP, the speedbrake extends with the flaps HALF or FULL so long as the switch is held in EXTEND.

This is not recommended. The speedbrake operates normally on the ground.
