The technique taught by the RCAF for deadstick approaches on single engine jets works reasonably well for multis, viz:
Try to arrive over any available runway at 5000' above ground (or multiples thereof) - at 210k. (Reckon on losing 5000' in a 360 turn)
At 5000' start an orbit with a view to arriving high on (shorter than usual) finals, selecting flap and gear as required (bearing in mind selections may be slow).
The important thing is to remain close to the field to maximise opportunities for emergency equipment.
It is better to slide off the far end of the runway at low speed than land short at high speed!
We found most pilots got it right first time after a suitable pre-briefing. Aircraft like the 757/767 are really quite good gliders!
