Hi enicalyth,

A 777 analysis would be great for the -300ER. I have some of my own models set up and running now which I have been calibrating against the data I've received and they are making sense for those few aircraft types, which (lucky dog) includes the 777-200LR and that is the aircraft I mentioned above. If you get the chance to take a look this weekend, I'd be very grateful. I've been previously using the BADA files for fuel consumption and there is something not quite logical about their 777-200 and -300 fuel consumptions; almost as if they are reversed. Hence I'm not quite sure about the -300ER.

And many thanks for the SENDIT performance data for the A319 operation. Since the A319 is something I was looking at for regional flights, and of interest, the CAA reserve fuel policies were something new to me for the isolated airport case:

Reserve fuel policy for normal CAA profile
En-route allowance : 5% of trip fuel and diversion fuel
Diversion to the diversion airport at LRC
30 min holding at 1500 ft above alternate

Reserve fuel policy for CAA profile isolated airport
En-route allowance : 5% of trip fuel and diversion fuel
Diversion reserve : continued cruise for 120 mn
30 min holding at 1500 ft above destination

You win on the French puns. My best is:

A. Un deux trois quatre cinq.
