Slat retraction after touchdown

[JSACKS 0]

Are the Queen's inboard and mid slats designed by Boeing to retract on application of reversers after TD? Why? (It's an amazing feature on this superb aircraft!)Jonathan

Jonathan,It's done to prevent FOD (foreign object damage) while the reversers are engaged since they could potentially kick up debris and hit the slats. Absolutely happens on the real plane and is by Mr. Boeing's impeccable design! ;)

I thought it was done to reduct lift and press the airplane against the ground harder.

I think the lift idea is more important tho.Paul

Perhaps it helps to reduce the risk of a spurious lift on the slats created by the airflow from the reverse thrust....?

Boeing tells us that the LE's are retracted to prevent damage to them during reverser operation. As aircraft maintenance engineers we "often" believe them ;)If it was to dump lift, why not retract _ALL_ LE's?CHeers.Q>
