Definition
An airplane with a maximum certificated takeoff weight of 12,500 pounds or less, as defined under 14 CFR Part 1.
Plain English
Under FAA rules, an airplane counts as 'small' if its maximum allowed takeoff weight is 12,500 pounds or less. The term is about a weight category set by regulation, not about how the airplane looks or feels.
Context Anchor
Seen in FAA handbooks, regulations, aircraft category discussions, and operating guidance that applies differently to smaller airplanes than to larger aircraft.
Derivation
In everyday speech, 'small' means physically little. In FAA usage, 'small airplane' is a defined regulatory category tied to a specific weight number, not to physical size.
Why Pilots Care
Determines which pilot certificate and operating rules apply to the flight.
Intuition Check
Do not judge “small airplane” by appearance or number of seats. In FAA use, the key point is the approved maximum takeoff weight: 12,500 pounds or less.
Example Sentence 1
Because the Cessna 208 has a maximum certificated takeoff weight under 12,500 pounds, it is classified as a small airplane.
Example Sentence 2
Small airplane operations under Part 91 do not require the same dispatch rules as larger aircraft.
