Below I have copied a question and answer that was posted on the NBAA website. Is this typical of how the NBAA fuel reserves are figured, or can they vary quite a bit depending on a lot of variables?

Also, in practice, do most corporate operators with turbojet aircraft adhere to the NBAA fuel reserve figure for their planes?

Here is the Q & A from the website:

Question: What is the exact flight profile used when calculating the "NBAA IFR reserve" range of an aircraft? It seems everyone uses different methods in their advertised ranges.

Answer: The exact flight profile for NBAA IFR reserves is complex, but to summarize it is as follows. Upon the execution of a missed approach at your destination airport the IFR reserves numbers start. First figure is fuel to climb to 5000’. Second, hold at loiter power for 5 minutes for IFR clearance. Third, fuel to climb to optimum cruise altitude. Fourth fuel for economy cruise. Fifth, fuel for decent enroute to sea level at 3000 FPM decent and land. Keep in mind that the distance from the primary airport to the alternate is 200 NM

The NBAA (National Business Aircraft Association) IFR Fuel Reserves simply set a list of specific conditions upon which the fuel, flight time, range, speed, etc. of an aircraft are compared with other aircraft. It helps to keep the manufactures honest and provides points to base performance comparisons on. Are they realistic? Probably not, but they keep everyone on the same playing field. I know of few crews who would cut it so close as to only have NBAA (or FAA, for that matter) minimums.

Thanks Jetguy!  Big thumbs up

Wihtout knowing much about it, I had thought maybe the NBAA created a set of fuel reserve guidelines that were much more conservative than the FAR's (with the idea that most corporate operators would generally follow them).

However, it sounds like it's actually used more to cut through some of the marketing hype in order to make an apples-to-apples comparison between planes.

Thanks again!
