Apologies for the thread creep here - maybe the mods would like to split this thread??
Ref SIDs and MSAs - surely the point is that AREA MSAs are not relevant on a SID, adherence to the track of which will achieve terrain clearance? Therefore it is perfectly safe to turn towards the high MSA area below relevant MSA
providing you are on the SID, and even have an engine or two out and be safe, assuming there is no terrain/emergency turn. If you look out of the right hand window on that SID on a nice day, you could even turn at 4500' (?? from a fading memory!!) and avoid terrain ON THE TRACK. Not encouraging you to do this, mind you!!
