caption_attribution_description: Graph of factors effecting the cg location of transport aircraft.
context_page_description: The center of gravity of an aircraft is the point over which the aircraft would balance. Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft. To ensure the aircraft is safe to fly, the center of gravity must fall within specified limits established by the aircraft manufacturer.
context_section_description: This section shows data obtained from a NASA Ames research grant for large commercial transport aircraft.
  The Operational CG Range is utilized during takeoff and landing phases of flight, and the Permissible CG Range is utilized during ground operations (i.e. while loading the aircraft with passengers, baggage and fuel).
