The conditions are flap-up full throttle and the standard temperature.
The standard temperature is? 15 degrees. We should add 0.8 gallons for engine startup, taxi and takeoff allowance.We can use the chart to the left to calculate how much fuel we will burn on our initial climb based on pressure altitude and temperature.

Conclusion

We need 1.5 gallons of fuel for startup, taxi, takeoff and climb, our flight is 1 hour long so we will need 5.1 gallons for that part, 5.1 + 1.5 is 6.6 gallons. We also need fuel for our reserve so if that is 15 minutes away that’s another 1.3 more or less, then we need 30 minutes of reserve fuel by law, so half of 5.1 is 2.6 and the total of fuel is.

  • Start, climb, taxi, takeoff and climb = 1.5
  • Cruise section = 5.1
  • Fuel to Alternate 10 mins = 1.3
  • 30 Min reserve = 2.6

Total fuel 10.5 Gallons rounded 11 gallons.
