yeah you're screwed BUT on the assumption you'll do something rather than nothing seems to depend where you think the best "fat" may be:
- in the SID even though you cannot meet the requirement you MAY be able to miss the hills by 1 foot rather than hit them by 1 foot;
- the EFATO procedure, even though off the exact track the lateral margin built into the procedure.
Of course local knowledge may assist in any decision, if you're in IMC an interesting period until the point of impact (or hopefully not!)
Personally reckon I'd go second option, max thrust, best climb and no cleanup until MSA - hopefully then head to the hotel and write the report.
And like Sully - only a "couple of seconds" to make a decision that the armchair warriors can pick to pieces in the days and month afterwards!
Cheers.
