What You'll Learn
Fuel burn rate is 5.5-6 gallons per hour
The fuel burn rate of a Cessna 150 is generally between 5.5 and 6 gallons per hour. This rate can vary depending on various factors, including power settings, altitude, mixture, wind speed, and aircraft configuration.
For example, one pilot reported burning 5.5 gallons per hour when flying at 2500 rpm and an altitude of 2500 feet. At 3500 feet, they burned 5.4 gallons per hour. Another pilot reported a burn rate of 5.6 gallons per hour at 2500 rpm.
It's important to note that the fuel burn rate will also depend on the specific model and year of the Cessna 150 aircraft. For instance, a 1968 model year Cessna 150H owner reported a fuel burn rate of 5.5 to 5.6 gallons per hour, while a 1966 model year Cessna 150 owner experienced a burn rate of 7.3 gallons per hour during a flight at 70% power.
To ensure safe flight operations, pilots typically calculate fuel requirements based on worst-case scenarios and include ample reserve fuel. For example, a pilot might estimate a fuel burn rate of 9 gallons per hour for a Cessna 150, even though the actual burn rate is closer to 6 gallons per hour. This conservative estimate helps ensure that the aircraft has sufficient fuel for the planned flight and can accommodate unexpected delays or changes in flight conditions.

Fuel cost per hour is $33-36
The fuel cost per hour for a Cessna 150 is estimated to be $33-36. This is based on the assumption that the aircraft burns around 5.5-6 gallons of fuel per hour at a price of $6 per gallon.
These estimates are supported by various pilots' experiences with the Cessna 150. One pilot reported that their 1968 model Cessna 150H burned approximately 5.5-5.6 gallons per hour, resulting in a fuel cost of around $33-36 per hour. Another pilot with a 1966 model also observed a fuel burn rate of 5.5 gallons per hour at an altitude of 2500.
It is important to note that fuel burn rates can vary depending on factors such as power settings, altitude, mixture, and wind speed, as well as aircraft maintenance. Some pilots have reported higher fuel burn rates, especially during climb conditions. For example, one pilot experienced a fuel burn rate of 7.3 gallons per hour during a 3-hour flight at 70% power.
To ensure safe flight operations, it is recommended to estimate fuel burn rates conservatively and always maintain adequate fuel reserves. Some pilots suggest using 150% of the expected fuel burn rate when planning flights to account for potential variations and ensure sufficient fuel for the journey.

Fuel burn is affected by the type of propeller
The fuel burn of a Cessna 150 is influenced by various factors, including the type of propeller equipped on the aircraft. In a discussion on fuel burn rates, pilots shared their experiences and offered insights into the role of propeller choice.
One pilot, flying a 1966 Cessna 150, encountered an issue where their aircraft burned more fuel than expected during a 3-hour flight at an altitude of 3500 feet with the engine set at 2500 RPM. They attributed this discrepancy to the use of a climb prop, which is designed for ascending to higher altitudes, resulting in reduced cruise performance and increased fuel consumption. This was further supported by another pilot, who agreed that a climb prop would underperform during cruise flight and contribute to higher fuel burn rates.
The choice between a climb prop and a cruise prop can significantly impact fuel efficiency. Climb propellers are optimized for ascending to higher altitudes and are expected to provide reduced cruise performance. On the other hand, cruise propellers are designed for efficient flight at cruising altitudes, typically resulting in lower fuel consumption.
Additionally, propeller efficiency plays a role in fuel burn rates. A pilot commented that running the engine at lower RPM can significantly improve fuel efficiency. Operating the engine at 2500 RPM was identified as a potential contributor to increased fuel burn. By reducing the RPM, pilots can achieve more economical fuel consumption during cruise flight.
In summary, the type of propeller installed on a Cessna 150 can notably affect fuel burn rates. Climb propellers may offer inferior cruise performance and higher fuel consumption, especially on longer flights. On the other hand, cruise propellers are designed for optimized fuel efficiency during cruise flight. Moreover, fine-tuning engine settings, such as RPM, can help pilots minimize fuel burn and improve overall fuel efficiency.

Fuel burn is 4.1 gallons per hour at cruise power
The Cessna 150 is a single-engine aircraft that typically seats two people. It has a fuel capacity of 22.5 gallons, with 21 to 23 gallons being usable. The fuel burn of a Cessna 150 is influenced by various factors, including power settings, altitude, mixture, and wind speed.
At cruise power, the Cessna 150's fuel burn is approximately 4.1 gallons per hour. This means that with a full tank of 22.5 gallons, the aircraft can remain airborne for about five hours. However, it is important to note that this duration does not include the required fuel reserve.
Some pilots have reported higher fuel burn rates, such as 5.5 to 6 gallons per hour, which can be influenced by factors like engine settings, propeller type, and climbing or descending during flight. It is recommended to always plan for a fuel stop to ensure safe operations and avoid fuel exhaustion, which has been a factor in previous Cessna 150 incidents.
The cost of operating a Cessna 150 per hour, taking into account fuel prices, can vary from $33 to $36 per hour, depending on the price per gallon of fuel.

Fuel burn is 9 gallons per hour in a full-power climb
The fuel burn of a Cessna 150 depends on a variety of factors, including the aircraft's power setting, altitude, mixture, wind/ground speed, and propeller type. While some sources suggest that the average fuel burn for a Cessna 150 is between 5.5 and 6 gallons per hour, this can vary depending on the specific aircraft and flight conditions.
In a full-power climb, the fuel burn of a Cessna 150 can be significantly higher than the average. According to one source, a Cessna 150 can burn up to 9 gallons of fuel per hour during a full-power climb. This is significantly higher than the average fuel burn and is likely due to the increased power settings and reduced efficiency during the climb.
It is important for pilots to be aware of the increased fuel burn during a full-power climb and to plan their fuel usage accordingly. Failing to account for the higher fuel burn rate during a climb can lead to fuel exhaustion, as described in several incident reports involving Cessna 150 aircraft. In these incidents, the pilots failed to adequately plan for their fuel usage, leading to dangerous low-fuel situations and even crashes.
To avoid such incidents, pilots should calculate their fuel requirements based on worst-case scenarios and always carry a minimum fuel reserve. By planning for higher fuel burn rates, such as 9 gallons per hour during a full-power climb, pilots can help ensure they have sufficient fuel for their flights and avoid potentially dangerous situations.
Additionally, pilots can consider ways to optimize their fuel efficiency during climbs. This may include adjusting power settings, using climb propellers that are designed for improved climb performance, or utilizing techniques such as leaning the mixture to ensure the engine is running efficiently. By combining efficient climbing techniques with careful fuel planning, pilots can help ensure safe and economical operation of their Cessna 150 aircraft.
