I am confused, surely the LE devices would extend again as soon as the craft got airborne.
From another thread...
Automatic Leading Edge Flap Retraction
Group A leading edge flaps are automatically retracted during ground
reverse thrust operation in order to improve structural life of the flap
panels. The function is armed when the airplane is on the ground and
the flaps are operating in the pneumatic mode.
Group A leading edge flaps retract when armed and engines 1 and 4
are placed in reverse thrust or engines 2 and 3 are placed in reverse
thrust. The flaps re-extended when the reverse thrust signals are
removed.
NOTE:
Thrust reverser operation is defined as reverse thrust
selected or airmotor brake released or gearbox unlocked
on a symmetrical pair of engines.
Not questioning the integrity of the reports, just asking the question that's all.
