Any 747 drivers?
Is Foreflap a term used?
Need to check my 737 stuff ,but looks a lot like the forward section on the Dobbel slotted Fowler flaps?
As opposed to the basic Leading edge Flaps inboard on the 737.
And as David said: Could it possibly be missed on a walk around.( Never mind indications in flightdeck)
Oh
And stuff that float often go walkabout a lot in current and wind before a quick rest at the beech!
