Thrust Reverser Effects On Touchdown
Hi All,
I read in Park's notes for A320:
"Be careful not to let the nose ride up when reverse is selected. Select Full Reverse as you lower nose."
Why would this happen when the moment of opposite thrust force ("braking" force on the engines) would naturally pitch down the nose (aircraft CG is above the line of thrust)?
Maybe because of the combined effect of spoilers on touchdown? Effect of angled reverse jet flow?
OR, because choosing reverser first on IDLE during touchdown doesn't produce large reverse force, but cancels forward thrust, therefore suddenly unbalancing all of the moments around CG?
Both textbooks and FCOMs that I read state that reverser operation is possible already when main LGs are compressed. Why not wait for the nose gear because of these pitch moments?
