Definition
A characteristic of an aircraft, typically a training airplane, that burns a relatively small quantity of fuel per hour of operation, resulting in lower direct operating costs.
Plain English
The airplane doesn't burn much fuel per hour, so it costs less to fly.
Context Anchor
Seen when comparing flight school airplanes, training costs, cruise engine settings, and aircraft operating expenses.
Why Pilots Care
Directly affects hourly training costs and determines how many students a school can keep airborne on a limited fuel budget.
Intuition Check
Low fuel usage does not mean the airplane has a low amount of fuel on board. It means the airplane uses fuel at a lower rate while it is operating.
Example Sentence 1
The school chose the Cessna 152 as its primary trainer partly because of its low fuel usage, which kept hourly rental rates down.
Example Sentence 2
By maintaining best economy power settings the student achieved noticeably lower fuel usage on the cross-country leg.
