Watch ya gonna do, decisions ya gonna make, Sully, in the next 15-30 seconds regards your tracking??

Bear in mind few companies - probably most - will not provide crew with anything more than an EFATO procedure and only that because the insurance (apologies, regulators - silly me!) require it.

Cheers.
It is a good question and real world. But I think a real world answer is still.....It depends on the situation. But lets make the scenario even worse by stating that you are unfamiliar with the airport as well and no ATC radar vectors available to save the day.

All you know is that there is terrain out there and the MSA is well above your altitude.

So how about after making sure that the aircraft is under control, that you select the terrain function to be displayed on your ND(if it wasn't already selected). The manual says that it is not to be used for navigation. But seeing as you could easily justify this as an emergency(even for an aircraft with more than two engines), consider using the terrain database for navigation. It may confirm that the SID route will clear the terrain as it was your lucky day and the routing goes through a valley. MSA of 5000 can sound bad but it could be just one peak that was off to one side of you and several miles away.

But if you can't clear the terrain on the SID route, it might be wise to stay slow to allow more time and tighter turn radius and avoid terrain using the terrain function(in other words. Worry about retracting flaps and accelerating later unless you really need to).

If close-in terrain is all around and is above your altitude, hopefully you have enough space to continuously circle and climb above the terrain or somehow set yourself up for a return to the airport. Remember to compensate for wind drift while doing your circling maneuver.
