1) Given: FL 250, OAT -150C, TAS 250 kt. Calculate the Mach No.
2) Given: TAS = 485 kt, OAT = ISA +100C, FL 410. Calculate the Mach Number.
3) Given: TAS = 197 kt, True course = 2400, W/V = 180/30 kt. Descent is initiated at FL 220 and completed at FL 40. Distance to be covered during descent is 39 NM. What is the approximate rate of descent?
4) The navigation plan reads:Trip fuel: 136 kgFlight time: 2h 45minCalculated reserve fuel: 30% of trip fuelFuel in tank is minimum (no extra fuel on board)Taxi fuel: 3 kgThe endurance on the ICAO flight plan should read:
