"Can we continue to use the existing OEISIDs?"
Our initial stab at EFP's uses a range of speeds that cover all of our aircraft, if the resulting weights are sufficient for the sectors operated from that airport, then the procedure is adopted for all aircraft, if payload isnt sufficient, then the procedure is altered for 1 aircraft type, i.e. max speed 150KIAS.
It makes life easier, especially as we operate about 12 aircraft types!
