MASTERING AIRCRAFT WEIGHT AND BALANCE

Apply ICAO annex six operations to load aircraft correctly, keep the center of gravity within limits, and follow airworthiness manual’s mass and balance requirements for all cargo, including dangerous goods.

Explore Iata documents related to weight and balance, including the airport handling manual and afm chapter five, outlining load planning, cg calculations, and key roles.

Learn why ICAO uses mass rather than weight, aligning with Si units, and how mass and balance terminology ensures global standardization across flight operations and regulatory records.

Explore how the aircraft flight manual defines max weights and cg envelopes, and how the weight and balance manual and part b guide load calculations, documentation, and compliance.

Explore how the load sheet and trim sheet document weight and balance for safe flight, with CG calculations and weight limits used by pilots, load controllers, and dispatchers.

Explore the four fundamental aerodynamic forces—lift, weight, thrust, and drag—and how their balance drives safe flight and stability.

Apply the moment of a force to see how force and distance create torque. Longer distances amplify moments, guiding load planning to maintain center of gravity with multiple weights.

Apply force through the center of gravity for linear motion; apply force away from the CG to create a rotational moment that powers elevators, rudders, and ailerons for attitude.

The center of gravity is the average location where the entire weight acts, and staying within manufacturer or operator loading limits ensures aircraft stability, control, and safe flight.

Compute each object's moment about a reference point using the correct sign convention, sum moments and masses, then divide total moments by total mass to locate the center of gravity.

Apply the center of gravity method to determine the center of gravity of mass systems using moments, total mass, and a reference point, with step-by-step practice problems.

Apply center of gravity principles to aircraft weight and balance by calculating moments from gear weights and their arm distances from a datum, ensuring safe loading within balance limits.

Explore the range of the center of gravity as a safe envelope with forward and aft limits to maintain aircraft controllability, balance, and flight safety.

Explore how basic empty weight underpins all weight calculations and how dry operating weight, operating weight, payload, and ramp, takeoff, and landing weights govern performance and balance.

Explore ICAO and ERA defined fuel quantities, including taxi fuel, trip fuel, contingency fuel, alternate fuel, final reserve, additional view, and extra fuel, to ensure safe, efficient flight planning.

Apply weight and balance concepts to a four-seater, perform CG calculations at zero fuel, takeoff, and landing, assess limits, and propose forward weight redistribution by swapping passengers to restore balance.

Explore how forward and aft loads shift the aircraft's center of gravity and how a load sheet graph guides weight and balance to stay within CG limits.

Define the main aerodynamic chord (Mac) for a tapered wing, locate the lemac and tmac, and express CG as a percentage of Mac for stability and balance.

Apply a practical four-seat weight and balance exercise by calculating the mean aerodynamic chord (Mac) and CG as a percent of Mac; CG at 35% Mac lies within 28%–66% limits.

Calculate the mass to shift to place the cg at a desired location using the moment balance equation, considering cargo compartments, unchanged moments, and reference distances.

Apply proportional allocation, or rule of three, to assign passengers to forward, mid, and aft zones based on each zone's maximum capacity, preserving balance and CG.

Apply proportional distribution using the rule of three to allocate cargo across four compartments, maintaining centre of gravity and safe load limits for aircraft.

Define and interpret mac, lemac, and temac within the aircraft reference system and CG limits, and apply a practical example locating CG within the 31 to 34 m safety zone.

Maintain the center of gravity within prescribed limits to ensure longitudinal stability and predictable elevator authority, while forward CG increases drag and fuel use and aft CG reduces stability.

Explore the Boeing 737 certified center of gravity, its CG envelope from 6% to 32% of Mach, and structural and weight limits including max taxi and max landing weights.

Learn to use the index, a scaled moment, to simplify weight and balance calculations, build load sheets and CG graphs, and apply offsets to keep indices positive for safe loading.

Learn to complete a manual load sheet and balance chart, distribute passengers and cargo, calculate weights, and verify takeoff weight and CG stay within limits.
