Plain English Meaning

Rules that tell the pilot how heavy the aircraft is allowed to be and how that weight must be distributed front to back. Stay inside the limits and the aircraft flies as designed. Go outside them and it may not fly safely.

Full Definition

The published limits placed on an aircraft that specify the maximum allowable weight and the permissible range of center of gravity (CG) locations under which the aircraft may be safely operated. These restrictions are set by the manufacturer, approved by the certifying authority, and listed in the Pilot's Operating Handbook (POH) or Airplane Flight Manual (AFM). Operating outside these restrictions is prohibited because doing so can compromise structural integrity, , and .
