The mains move sidewards, so the air load is less harmful. At what speeds can I start to partly lower the flaps down to +5=B0 or = +10=B0 (below fuselage fairing). My flaps have a hinge on all the = length and also the 7bids glass under the wing side of the hinge at all the length. Max extension speed = is 100kts.
