Re: In Response to a .....

Two points.

One simple. Since distance can be found from (V^2-u^2)/2a assuming constant decel, a 20% change in distance requires a 20% change in accel (decel) and, all other things being equal a 20% change in force. Assuming only wheel brakes are causing any decel that means 20% more braking force, and 20% more mainwheel reaction.

Secondly, there seems to be an implicit assumption that the nosewheel is NEVER going to rise. This is not the case; on our types the 'stick forward' SOP is designed to prevent precisely that, based on experience in flight test. That simple fact is what leads me to plead that at least pilots of our types NOT try this at home.
