This is an interesting issue.Basically its the same everywhere now, as mandated by ICAO.For most situations the FINAL RESERVE is equivalent to 30 minutes of endurance fuel based upon holding at 1500 feet overhead an airfield.This will vary with weight, but what is not stated is lets say you TOUCHDOWN with 30 minutes in tanks then have a long taxi then get ramp checked on engine shutdown? Are you a criminal?.If not why not?
