Smokey & Oz,
Thanks for the replies.
It's interesting that you should single out my comment about being "happy to follow the SID or OEI procedure". I think I meant to say "happy to follow the OEI procedure, or the SID if there isn't one..."
In my company we have datalinked performance accomodating environmental conditions and any MEL/perf. restrictions. It generally produces a TOPL and then a small selection of assumed temperatures around the ATOW. It will also say things like: "No restriction if SID followed", "Engine failure turn right TRK 210 climb 3000 before return" or "EO accel. ht. 2400", etc. Maybe I'm putting too much trust in the printout but I was hoping that as it was written down somebody/thing might have checked it...
I have to say I generally brief as I said above, as I share the misgivings around pilot-invented OEI procedures. I do vary this sometimes, in places like Kingston, where the sea is at the end of the runway and our ET takes us back over the hills where the storms usually sit. I'd much rather go and dump fuel 10 miles offshore than hold inside a cu-nim on one engine.
