## Who is responsible for the correct weight and balance of every flight?

The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable gross weight of the aircraft and its CG limits. This allows the pilot to determine, on the preflight inspection, that the aircraft is loaded in such a way that the CG is within the allowable limits.

## Who is responsible for the proper loading of an aircraft prior to takeoff?

The pilot controls loading and fuel management (the two variable factors that can change both total weight and CG location) of a particular aircraft.

## How do you weight and balance an aircraft?

Ascertain from the pilot’s operating handbook the empty weight of the aircraft and determine the weights of people, baggage, and fuel. Multiply each weight by the arm—the distance from the reference datum—to find the moment. Add all the weights to find the gross weight. Add all the moments to find the total moment.

## What determines the weight of an airplane?

For an airplane, weight is always directed towards the center of the earth. The magnitude of this force depends on the mass of all of the parts of the airplane itself, plus the amount of fuel, plus any payload on board (people, baggage, freight, …).

## How weight and balance affect the performance of an aircraft?

Weight and balance have a direct effect on the stability and performance of the aircraft. If a plane is too heavy, it may never get off the ground. If it’s out of balance, it may be uncontrollable when it does take flight. … Maintaining proper weight and balance is an extremely important balancing act.

## How is weight balance calculated?

## What tasks are completed prior to weighing an aircraft to determine its empty weight?

What tasks are completed prior to weighing an aircraft to determine its empty weight? Remove all items except those on the aircraft equipment list, drain fuel and fill hydraulic reservoir.

In order to provide safe flight operations, the pilot must maintain the total, or gross, weight of an airplane at or below maximum limits. These maximum weights are primarily established to maintain structural integrity of the airframe up to the limit load factors during all phases of flight.

## How does weight affect aircraft performance?

When weight is increased on an aircraft, it needs to fly at a higher angle-of-attack to produce more lift, opposing the aircraft’s increase in weight. This increases both the induced drag created by the wings and the overall parasite drag on the aircraft. … Power is needed to overcome any increase in drag.

## How often does an aircraft need to be weighed?

When operating under FAR 135, an aircraft must be weighed every 36 calendar months to establish its current empty weight and center of gravity.

## What is minimum fuel in aviation?

Minimum Fuel. … “Indicates that an aircraft’s fuel supply has reached a state where, upon reaching the destination, it can accept little or no delay. This is not an emergency situation but merely indicates an emergency situation is possible should any undue delay occur.”

## How do you calculate CG weight and balance?

Center of gravity (CG) is calculated as follows:

1. Determine the weights and arms of all mass within the aircraft.
2. Multiply weights by arms for all mass to calculate moments.
3. Add the moments of all mass together.
4. Divide the total moment by the total mass of the aircraft to give an overall arm.

## What is maximum all up weight?

The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation. An aircraft’s gross weight will decrease during a flight due to fuel and oil consumption.

The mass of an object is a measure of the object’s inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.
