Fuel burn rate: 5.5-6 gallons per hour
The Cessna 150 is a small, two-seat, single-engine airplane that was introduced in 1959. It has a fuel capacity of 22.5 gallons, with 21 to 23 gallons being usable. The fuel burn rate for this aircraft can vary depending on various factors such as power settings, altitude, and engine RPM.
According to some pilots, the Cessna 150 can have a fuel burn rate of around 5.5 to 6 gallons per hour. This rate may be achieved at an altitude of 2500 feet and an engine RPM of 2500. However, it's important to note that these values can vary depending on other factors, such as the type of propeller used and the age of the engine.
One pilot shared their experience of burning 7.3 gallons per hour during a 3-hour flight at 70% power, which is significantly higher than the expected fuel burn rate. This discrepancy could be due to the use of a climb propeller, which can result in higher fuel consumption during cruise.
Another pilot with a 1968 model of the Cessna 150 shared that their calculations based on time to climb tables, taxi time, and other factors resulted in a fuel burn rate of under 6 gallons per hour, typically around 5.5 to 5.6 gallons per hour.
To ensure safety, it is recommended to estimate the fuel range in terms of the worst-case scenario, using a conservative figure of 150% of the expected fuel burn rate. This would mean planning for a fuel burn rate of 9 gallons per hour for the Cessna 150, which has an average fuel burn of 6 gallons per hour.
Additionally, it is worth noting that the fuel burn rate can also depend on the specific variant of the Cessna 150. For example, the Cessna 150J with an O-200A engine has a fuel burn rate of 5.6 gallons per hour at 2500 RPM, while burning about 9 gallons per hour in a full-power climb.
Overall, the Cessna 150 is considered relatively fuel-efficient compared to similar aircraft, such as the Cessna 152, which has a slightly higher fuel burn rate.

Fuel tank capacity: 22.5 gallons
The Cessna 150 is a small, two-seat, single-engine airplane that was introduced in 1959 and remained in production until 1978. It has a fuel capacity of 22.5 gallons, with 21 to 23 gallons being usable. The exact fuel burn rate can vary depending on various factors such as power settings, altitude, and wind speed. However, on average, the Cessna 150 burns around 5.5 to 6 gallons per hour (GPH) when properly leaned. This burn rate can increase to about 7 gallons per hour at 70% power or 9 gallons per hour during a full-power climb.
It is important to note that the fuel burn rate is also influenced by the type of propeller used. A climb prop, for instance, can result in worse performance during cruise, leading to higher fuel consumption. Additionally, the engine's revolutions per minute (RPM) play a significant role in fuel burn. Operating the engine at higher RPMs, such as 2500 RPM, can contribute to increased fuel burn.
To ensure safe operations, pilots should consider a conservative approach when estimating fuel burn. One suggestion is to use 150% of the expected fuel burn rate and plan for a minimum reserve of one and a half hours. This conservative estimation helps mitigate the risk of fuel exhaustion, which is a contributing factor in many general aviation accidents.
By being mindful of the fuel burn rate and adopting conservative planning practices, pilots can make informed decisions about their flight duration and the need for additional fuel stops. Proper fuel management is crucial for the safe operation of the Cessna 150 and helps ensure a successful flight.

Engine power: 100 horsepower
The Cessna 150 is a two-seat, single-engine aircraft introduced in 1959. The first C-150s were produced with a 100-hp Continental O-200 engine, with a "turtledeck" fuselage, no back window, and a straight, squared-off tail.
The fuel burn of the Cessna 150 is approximately 5.6 gallons per hour (gph). This value can vary depending on various factors, such as engine age, rpm, and flight conditions. Some pilots have reported fuel burns of around 5.4 to 5.5 gph, while others have experienced higher values, such as 6 to 7.3 gph, under certain conditions.
To estimate the fuel burn for a Cessna 150 with a 100-horsepower engine, a rule of thumb is to divide the horsepower rating by 10 and then half that value. Using this formula: (100 HP / 10) / 2 = 5 GPH. This calculation provides a rough estimate of the fuel burn for the aircraft.
It is important to note that fuel burn can vary based on various factors, including flight conditions, engine maintenance, and individual aircraft characteristics. Pilots should always refer to the aircraft's official documentation, such as the Pilot's Operating Handbook (POH), and exercise their best judgment when planning fuel requirements for a flight.

Fuel cost: $33-36 per hour
The Cessna 150 is a small, two-seat, single-engine airplane that was introduced in 1959. It has a fuel capacity of 22.5 gallons, with a range of 4.1 to 4.5 hours. The fuel burn per hour ranges from 5.4 to 7.3 gallons, depending on various factors such as power settings, altitude, and engine RPM.
The fuel cost per hour for a Cessna 150 can be estimated by multiplying the gallons burned per hour by the price per gallon of fuel. For example, if the plane burns 5.5 gallons per hour and the fuel costs $6 per gallon, the fuel cost per hour would be $33.
Assuming a fuel price of $6 per gallon, here are some estimates for the fuel cost per hour at different burn rates:
- At a burn rate of 5.5 gallons per hour, the fuel cost would be $33 per hour.
- At a burn rate of 6 gallons per hour, the fuel cost would be $36 per hour.
- At a burn rate of 7 gallons per hour, the fuel cost would be $42 per hour.
It is important to note that these estimates do not include other operating costs, such as maintenance, hangar fees, or insurance. Additionally, fuel prices can vary, which would impact the overall fuel cost per hour.
Overall, the fuel cost for a Cessna 150 is estimated to be between $33 and $36 per hour, depending on the burn rate and fuel prices.

Fuel burn calculation: gallons x price = fuel cost per hour
The fuel burn of a Cessna 150 can vary depending on various factors such as power settings, altitude, and engine RPM. According to several sources, the average fuel burn for this aircraft is around 5.5 to 6 gallons per hour (GPH). However, some pilots have reported fuel burns ranging from 5.4 GPH to 7.3 GPH, depending on their specific aircraft and flight conditions.
Now, let's focus on the fuel burn calculation: 'Gallons x Price = Fuel Cost per Hour'. This equation will help you determine the cost of operating a Cessna 150 per hour, based on the fuel burn and the price of fuel.
For example, let's assume that your Cessna 150 burns an average of 6 gallons of fuel per hour. Now, you need to find out the current price of aviation fuel, which we'll say is $6 per gallon. By substituting these values into the equation, we can calculate the fuel cost per hour:
6 gallons x $6 per gallon = $36 per hour
So, in this example, operating a Cessna 150 would cost approximately $36 per hour, considering only the fuel expenses. It's important to note that fuel prices can vary over time and across different locations, so make sure to use the most up-to-date and relevant fuel price for your calculations.
Additionally, it's worth mentioning that some pilots recommend adding a buffer to their fuel burn calculations to account for potential variations and ensure adequate fuel reserves. For instance, one pilot suggests using 150% of the expected fuel burn when planning flights, which would translate to 9 gallons per hour for a standard burn rate of 6 gallons per hour. While this approach may result in more frequent fuel stops, it prioritizes safety and helps prevent fuel exhaustion, which has been a contributing factor in many general aviation accidents.
In summary, the fuel burn calculation 'Gallons x Price = Fuel Cost per Hour' is a valuable tool for Cessna 150 owners and pilots to estimate their hourly operating costs. By understanding the average fuel burn of your aircraft and the prevailing fuel prices, you can make informed decisions and ensure a safe and economical flying experience.
