I never cease to be amazed at the number of crew who believe that they are protected for obstacles when they fly a SID with an engine out.
A good service provider will supply OEI data to comply with the SID (usually much more restrictive)
Not always true, we have particular airports where we know the required takeoff weight, its not achievable on any of the SID tracks. Therefore the OEI is unique.
The procedures are created by performance engineers poring over incredibly large scale survey charts, municipal maps, etc...stuff that is not available amongst normal aeronautical charts etc.
I would love to say that this is always true
I would love to see
ICAO level, for standard, optimised, OEI escape routes for all runways. It would make life so much easier and safer.
