How many gallons 100LL are required by cessna 152 to fly an hour?
November 21, 2008
The fuel consumption depends on the power setting and the altitude at which you intend to fly. A rough average for a Cessna 152 is around 5-6 gallons per hour, but it can range from about 4 to 7 gallons per hour. At todays prices that is around $25 to $30 per hour in fuel cost in the US.
In response to the person who said it is determined by weather is wrong. The weather (wind in particular) may determine the total fuel you need to carry to reach your destination, and temperature does play a very small part in absolute fuel consumption at a given altitude, but overall it is altitude and power setting that determine how much fuel you will use.
You also do not always need to depart with full fuel tanks on every flight. That is a completely erroneous statement. The Cessna 152 holds approximately 4 hours worth of fuel, so if you only need to fly for an hour to get where you're going, you obviously don't need full tanks. And there's a weight consideration. If you have two heavy occupants (say 200lb each) plus a bit of luggage you cannot carry full fuel or you'll be over weight. In that case you carry less fuel to remain within the maximum gross weight of the aircraft and you plan to stop more often to refuel

Got something to say?
~6-8gph

Hopefully you are not planning to fly it yourself if you are asking such a safety related question here.

The fuel burn in any plane would depend on the weather conditions. #1 you always fly with FULL fuel and always check to make sure you visual see the fuel is topped off. I fly the Cessna 152 and on an a good day it will burn 5 1/2 gallons an hour Solo.
