Is there much of a difference in Vref between a F25 landing and a F30 landing, assuming same weight etc?
After increasing the stress, failures were occuring. Indeed, one Classic, circuit bashing empty at Prestwick had the rear inboard flap unit detach at one end, swing around and burst through door 4R like a spear and go through a few rows of seats. The photos were shocking.
Thank god it was empty!
