Load balancing in air travel aims to distribute passengers and cargo evenly across multiple flights to ensure efficient utilization of aircraft capacity, optimize flight schedules, and minimize the risk of overcrowding or underloading.

Weather conditions and expected turbulence are not directly considered when determining the load distribution for an aircraft. These factors are primarily taken into account during flight planning and may influence the routing and scheduling of flights, but they do not directly affect the load distribution.

Weight and balance adjustment is the process of adjusting the load distribution of an aircraft after passengers and cargo have been loaded to ensure that the aircraft is within its weight and balance limits and that the center of gravity is within the allowable range.

Gross takeoff weight is the maximum allowable weight that an aircraft can carry at takeoff, including the weight of the aircraft, passengers, cargo, and fuel.

Landing weight margin is the difference between the gross takeoff weight and the maximum landing weight of an aircraft. It represents the amount of weight that can be burned off during flight, typically through the consumption of fuel, to ensure that the aircraft is within its maximum landing weight at the time of landing.

Rearranging the seating configuration of the aircraft is not a method used to achieve load balancing in air travel. Load balancing is typically achieved by adjusting the number of passengers and cargo on each flight, redistributing cargo within the aircraft, or changing the flight schedule to spread out demand.

The primary purpose of weight and balance adjustment in air travel is to ensure that the aircraft is within its weight and balance limits, which are established to maintain the aircraft's stability, controllability, and structural integrity during flight.

Center of gravity is the point at which the weight of an aircraft is evenly distributed along its longitudinal axis. It is a critical factor in determining the aircraft's stability and controllability.

Center of gravity envelope is the range of acceptable center of gravity positions for an aircraft. It is defined by the aircraft's manufacturer and is based on structural and aerodynamic considerations.

Improved passenger comfort is not a consequence of improper weight and balance adjustment in air travel. Improper weight and balance adjustment can lead to reduced stability and controllability of the aircraft, increased risk of structural damage, and reduced fuel efficiency.

Weight and balance computation is the process of calculating the weight and balance of an aircraft, taking into account the weight and distribution of passengers, cargo, fuel, and other items on board.

The maximum allowable center of gravity position for an aircraft is the aft limit, which is the most rearward point within the center of gravity envelope.

Center of gravity margin is the difference between the actual center of gravity position and the forward limit of the center of gravity envelope. It represents the amount of weight that can be shifted forward without exceeding the forward limit.

Weather conditions and expected turbulence are not factors that directly affect the weight and balance of an aircraft. These factors may influence the flight planning and routing, but they do not directly impact the weight and balance calculations.

Trim adjustment is the process of adjusting the aircraft's trim to compensate for changes in weight and balance. This is done to ensure that the aircraft maintains the desired attitude and flight characteristics during flight.
