A hair-on-fire whip back around to the runway before you have a handle on any of these things
a tight turn to short final?
Well these words are yours not mine.
I reiterate for the benefit of any younger pilots reading....
DO NOT PROLONG a flight with UAS having
confirmed the problem just after liftoff.In the cruise over the ocean,fine....follow the advice of derfred/vessbot.
Why climb?You lose your one remaining working altitude reference(radalt)?At low altitude your IRSGS readout
is close to IAS.At altitude it is not.ATC will have the false data from the transponder and cant help you.Keep your takeoff configuration and turn downwind at 2000' radalt,level off, and set thrust to 60% N1.The Boeing checklist of 10deg/80% is not correct for this scenario and will climb you above 2500.Its not a "hair on fire whip back around" at all.No tight turns required just basic attitude thrust flying.
