Learjet 135 180 ETOPS EO speed
Has anyone come up with a reasonable engine inoperative speed for Learjets (circa 31) to comply with staying under the 180 ETOPS limit for FAR 135? The only published OE speed is long range cruise, in the AFM – way too low for ETOPS computations – need a minimum of 335 TAS.
I’m from 121 Ops and haven’t had to deal with this before – but where do you go? Does Lear (now Bombardier) provide these numbers or would you look to SABRE or some other Computer Flight Plan Service?
Apologize for such a basic question – I’m new at this game – in this type of equipment.
Thanks for any information or suggestions.
