Hi Snakecharma,
'...so the easier you can make the procedure whilst not penalising yourself too much in relation to payload, so that when you have the "oh ****" moment it doesn't turn to crap.'
I absolutely agree. I think there's considerable potential for a f@#k up when continuing the SID after suffering an engine failure on the runway. A heavy aircraft would have to initiate the turn at very low altitude and any delay 'sorting the ****' potentially puts it very close to the terrain to the south-east.
