Well well well, at my airplane I might (per CL) retract at 400ft & V2 +10.
V2 s are between 103 and 122 for Flaps 7° and 99 to 115 at 15°.
So IŽd retract flaps with say 132 knots or 109 as the lowest figure.
Venr. is 180 KIAS.
IŽd have to accelerate beteen 48 and 71 knots to get back to 'know territory'.
Flaps can be carried up to 200 Kias (15°) and 250 (7°).
We prefer 7° over 15° for much better second segment climb gradients. FSI/Cessna teach 15° for less wear and tear on the tires.
IŽm not so sure that IŽd stay above the required profile with an engine failing just as the flaps hit their up stops. Definitively not if IŽd accelerate. CanŽt gain that much height over distance up to 400ft methinks. At least there is no way to determine that easily, which is a requirement for dumb pilots such as myself...
But then the answer to the question is easy. not in the book, thus can`t happen. Done.
