Guide to Propulsion
Range
and Fuel Consumption
Answers
- You are an acrobatic
pilot getting ready to go to an airshow. The airshow is being held
at an airport 500 nautical miles (NM) away. Given the cruising speed
of the Extra 300 you are flying, how long will it take to fly
to the airshow?
2.8 hours
- In the situation
above, will you be able to fly to the airshow without refueling along
the way? NO
Why or why not? Because the range
of the Extra 300 is only 462 NM
- A Cessna Skylane
has a range of 820 NM, and a cruising speed of 140 KTS. How many hours
will it take you to fly 820 NM? 5.85 hours
- Since the Skylane
has a fuel capacity of 88 US GAL (including 10% in reserve), how many
gallons of fuel per hour does it use? 13.67
gal/hour
- You are flying
a Cessna Skylane at a speed of 120 KTS. You are flying on a
trip that will take you 520 NM. How long will it take you to get to
your destination? 4.33 hours
- In the situation
above, given that your Cessna holds
88 US GAL of fuel (with 10% held back as reserve fuel), how much fuel
will you use? (Hint: you will need your final answer from Question
4 above to find this number.)
59.19 gal
- You are the pilot
of a Learjet 31A leaving Chicago's Meigs airfield under dense
fog conditions. You must fly using your instruments (IFR). How much
fuel do you have for this flight? (Don't forget about your reserves.)
2,588 lbs
- You've been flying
the Learjet for 1.5 hours, at a speed of Mach .76 (Visit the
Conversion page
to convert Mach numbers into Knots.), under visual flight conditions
(VFR). How much fuel do you have left (excluding reserves)?
1668 lbs.
- How much farther
could you fly on the fuel you have left from Question 8? 726.5
NM
- You are a WW-I
Sopwith Camel fighter pilot chasing the infamous "Red Baron."
You are traveling at a speed of 115 KTS. You know that your enemy
is 40 NM away from you. How many minutes will it take to reach him?
21 minutes
