How far can a Cessna 150-152 fly on a tank of gas ?
The Short Answer: This is a fairly simple math problem. For starters, we know that the Cessna will use between 5 and 9 gallons of fuel an hour, (depending on the individual plane, and how much throttle is applied by the pilot.) To keep this simple, let’s average the high and low fuel numbers, which gives us an hourly average of 7 gallons. We also know that the average airspeed is about 110 MPH. The normal tanks on a Cessna 150 contain 22. 5 gallons of useable fuel. We don’t want to run out of fuel, so let’s make sure we land with a half hour of gas left over. Using the average above, we will need 3.5 gallons in the tank when we land. That leaves us with 19 gallons of fuel to use for the flight. 19 gallons divided by 7 gives us 2.71 hours* X 110 miles per hour = 298 miles of range with a 30 minute reserve. *( 2 hours and 48 minutes )The Longer Answer: If we want to be more precise (and safe piloting technique requires that we do) we will need to pay attention to at least one more factor
