Definition
A weight limitation is a manufacturer-specified or regulatory maximum weight value that an aircraft, or a defined part of its loading, must not exceed during a particular phase of operation. Common weight limitations include maximum ramp weight, maximum takeoff weight, maximum landing weight, maximum zero fuel weight, and maximum weight in specific baggage or cargo compartments.
Plain English
A rule that sets the heaviest the aircraft, or a part of its load, is allowed to be at a given moment.
Context Anchor
Seen during weight-and-balance planning, before takeoff, and in the aircraft’s approved operating information.
Derivation
“Weight” means how heavy something is. “Limitation” comes from the idea of a limit or boundary. In aviation, the phrase means a boundary on aircraft weight that the pilot must stay within.
Why Pilots Care
Exceeding a weight limitation reduces climb performance, increases takeoff and landing distances, and risks structural overload or loss of control.
Intuition Check
Do not read “limitation” as general advice or a comfort margin. A weight limitation is an approved boundary: if the aircraft is outside it, it is not being operated within its allowed limits.
Example Sentence 1
Before loading the passengers' bags, the pilot checked the baggage compartment weight limitation listed in the POH.
Example Sentence 2
After adding passengers and fuel, the crew recalculated to confirm they remained within the landing weight limitation.
