Fuel burn per hour
The Cessna 150 is a light aircraft with a typical fuel capacity of 22.5 gallons, though some sources state 25 or 26 gallons. The fuel burn per hour for the Cessna 150 is estimated to be around 5.5 to 6 gallons per hour. This estimate is based on various factors, including power settings, altitude, mixture, and wind/ground speed.
One pilot reported that they flew fire patrol in a Cessna 150 all summer and, with it properly leaned, burned 5.5 gallons per hour. At this rate, they could fly for about 4 hours before the tanks ran dry, excluding the FAA-required 30-minute daytime reserve.
Another pilot reported that their Cessna 150 could use 80 octane auto gas and burned fuel at a rate of 6 gallons per hour. This is consistent with the estimated fuel burn per hour for the Cessna 150.
It is worth noting that the fuel capacity and burn rate can vary depending on the specific model and modifications made to the aircraft. Some Cessna 150s have long-range fuel tanks, which can increase the fuel capacity and, consequently, the range of the aircraft.
Additionally, the usable fuel capacity of the Cessna 150 is slightly less than the total fuel capacity due to the "unusable" amount of fuel that pools at certain angles of the aircraft. This unusable fuel can amount to about 1.75 gallons per tank, or 3.5 gallons total, which is crucial to consider when planning fuel needs for a flight.

The weight of the plane
The weight of the aircraft, including its fuel load, is an important consideration for pilots when planning flights. The Cessna 150's fuel burn rate is approximately 5.5 to 6 gallons per hour, which allows for a conservative flight duration of around 4 to 4.5 hours with a full fuel tank. However, it is important to note that various factors can influence fuel efficiency, such as power settings, altitude, mixture, and wind or ground speed. Therefore, pilots must carefully calculate fuel requirements and ensure that tanks are filled to capacity to avoid unexpected fuel exhaustion during flight.
The weight of the Cessna 150, including its fuel load, determines the maximum payload capacity for passengers and cargo. The combined weight of passengers and cargo must not exceed the aircraft's useful load capacity of 478 pounds when taking into account the weight of the fuel on board. Proper weight and balance calculations are essential for safe flight operations, ensuring that the aircraft remains within its certified weight and centre of gravity limits.
Additionally, the weight of the Cessna 150 can vary depending on the variant and optional equipment installed. For example, the original Cessna 150 model holds 6 quarts of oil, while the 1968-1977 models have a higher oil capacity of 7 quarts. Different fuel stick types, such as the Fuelhawk 152, can also impact weight readings due to differences in calibration and usable fuel calculations. Therefore, pilots and operators must carefully consider the specific weight characteristics of their Cessna 150 aircraft to ensure compliance with weight and balance limitations.
In summary, the weight of the Cessna 150 aircraft, including its fuel load, plays a critical role in determining its performance and capabilities. With a gross weight of 1,600 pounds and a useful load capacity of approximately 478 pounds, pilots must carefully manage fuel loads and passenger/cargo weights to ensure safe and efficient flight operations within the certified weight limitations of the aircraft. Proper weight and balance calculations, along with accurate fuel management, are essential for the successful operation of the Cessna 150.
