# When should an aircraft be weighed?

Contents

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

## Are planes weighed before takeoff?

Aircraft are not weighed prior to each flight, but the basic empty weight must be known and checked periodically per regulation.

## What are the major considerations in preparing an aircraft for weighing?

The major considerations in preparing an aircraft for weighing are described in the following paragraphs.

• Scale Preparation. Mechanical and electronic scales shall be inspected prior to use and set to zero. …
• Weigh Clean Aircraft Inside Hangar. …
• Equipment List. …
• Ballast. …
• Standard Weights. …
• Draining the Fuel. …
• Oil. …
• Other Fluids.

## How do you weigh an aircraft?

There are two ways to weigh an aircraft: using load cells, whereby the aircraft is lifted up, or using a weighing platform. For this weighing, the aircraft is pulled by a tow truck onto yellow platforms (see film). Each wheel has its own set of scales.

## Why it is important to follow step by step of weighing an aircraft?

The most important reason for weighing an aircraft is to find out its empty weight (basic empty weight), and to find out where it balances in the empty weight condition. When an aircraft is to be flown, the pilot in command must know what the loaded weight of the aircraft is, and where its loaded center of gravity is.

## Why do pilots salute before takeoff?

All pilots salute to signify they are ready for takeoff. They aren’t even supposed to put their arms above the canopy rail to avoid accidental shots. There are hold bars on the throttles of some planes to avoid a situation where the throttles go to idle during the shot.

## Do pilots die younger?

Preliminary study confirms that pilots die at younger age than general population. Flight Safety Foundation – Flight Safety Digest, 11(6), 1–6.

## 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 the Aircraft Specification or Type Certificate Data Sheet.

## What are the two most commonly used type of aircraft scales?

The two basic types of scales used to weigh aircraft are platform and load cell.

## Does weight affect aircraft range?

Variations in aircraft weight do not affect the glide angle provided that the correct airspeed is flown. Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. … The only effect weight has is to vary the time the aircraft will glide for.

## 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.”

## What is the weight shift formula?

Weight Shift

Instead of calculating a weight and moment for every section of the aircraft, it is only necessary to compute the original weight and moment—then, the effect of the change in weight. This is solved easily by cross-multiplying: 50 x 100 ÷ 8,600 = .

## Does empty weight include unusable fuel?

Basic Empty Weight – The starting point for weight computations is the basic empty weight, which is the weight of the standard helicopter, optional equipment, unusable fuel, and full operating fluids including full engine oil. … It includes the flight crew, usable fuel, drainable oil, if applicable, and payload.

## What is included in aircraft empty weight?

Standard empty weight (GAMA)—aircraft weight that consists of the airframe, engines, and all items of operating equipment that have fixed locations and are permanently installed in the aircraft, including fixed ballast, hydraulic fluid, unusable fuel, and full engine oil.

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

1-1] The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable weight of the aircraft and its CG limits.

## How does weight affect flight?

Weight is the force that pulls the plane down due to gravity. In order for the plane to get off the ground, the plane must overcome its weight throught the force of lift. The more mass the plane has the more lift it has to produce in order to get off the ground.
