- Given no thrust reversers available,
- Given slippery runway, i.e. braking action not limited by available brake pressure but but available vertical force on the wheels,
- Given that the elevator application were not so large that you would end up lifting the front wheel,
Then:
Wouldn't you get more braking by applying some back stick?
The force vectory diagram says so.
bm.
The same question is asked over and over again in different forms, but the answer remains the same.
By lowering the nosewheel to the runway, the reduction of angle of attack dumps lift, putting weight on the wheels. If you have a slippery surface, then reducing weight on wheels (by holding the nosewheel off, or maintaining an angle of attack which generates some degree of lift) only serves to reduce control and any available braking effect. The aerodynamic braking effect is negligible.
The size of the horizontal stab means that it's effect in slowing the airplane is largely inconsequential, particularly with respect to sub-reverser speeds...such as preparin to exit the runway.
For those who advocate holding the hosewheel clear of the runway, any development of assymetrical thrust or reverse compromises directional control authority at a time when rudder authority is rapidly decreasing. Putting the nosewheel on the runway enhances control.
Would you get more braking by applying back stick? Not enough to make a difference, and not enough to measure or see in real time.
