drauk, mate.
Please don't climb and say I said it was OK!!

If there
is an aircraft above at 3000, he will probably get a TCAS climb and there may be traffic descending on top of him!
Your calculation shows that there is no need for a climb really. Surely the last thing you should do when you lose your only engine is climb - and risk stalling in all the excitement.
Be safe - there's an urban jungle out there!!!
