jas24zzk has it in one. I am not advocating planning to use the 45 minute fixed reserve, I am just not sure that calculating that you will nudge into it and not instantly diverting is worthy of a $9000 fine.
Another one is that there is a blanket requirement to declare a mayday if you will land without the fixed reserve intact. If you don't then again another $9000.
6(4)The pilot in command must declare a situation of emergency fuel when the calculated usable fuel predicted to be available upon landing at the nearest aerodrome where a safe landing can be made is less than the fixed fuel reserve for the flight.
The other one is that previously the CAAP was advisory. The instrument is now regulatory and the way it is written it refers only to aerodromes for arrival, departure and destination. Too bad if you want to land at an ALA.
