standard procedures for each type of aircraft
You are not taking into consideration that there is 'more than one way to skin a cat' when it comes to designing EOSID.
Each company will have their own operating culture. The culture will have an impact on how the Performance Engineer goes about creating the escape procedure.
Will a straight ahead departure be preferred for simplicity?
Will a curved departure and FMS EOSIDs be preferred to maximise payloads?
Will the EOSID only meet the Regulator's performance requirements, or will it transition to a lowest safe altitude/MORA?
Good luck getting agreement across all B737/A320/insert type here operators on those items!
In the meantime, what is wrong with a PAN call followed by "engine failure indications, require runway heading to 3.5 dme, then a right turn track 270, standby for details."?
