What is a common average fuel burn rate per hour for single-engine aircraft?

The average fuel burn rate per hour for single-engine aircraft is typically in the range of 8 to 10 gallons. This rate can vary depending on the specific model of the aircraft, the weight it is carrying, and the conditions under which it is operating, but this range is commonly observed for many general aviation single-engine planes, especially those equipped with commonly used engines such as the Lycoming or Continental engines.

When considering efficiency and operational characteristics, fuel burn is an important factor for pilots to understand, as it directly affects range and operating costs. Knowing that many training and recreational single-engine aircraft operate within this fuel burn rate range enables pilots to plan flights better and manage fuel for a desired range or endurance.
