# What is the prescribed interval of individual aircraft weighing for maintenance?

Contents

The mass and CG position of an aircraft must be periodically re-established. The maximum interval between one aircraft weigh and the next, must be defined by the operator, but not exceed the four/nine year limits.

## How often should aircraft 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.

## How are planes weighed?

The weighing moment

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.

## What weight do airlines use for passengers?

Since 1995, most airlines have assumed a weight of 180 pounds for each adult passenger in summer and 185 pounds in winter; checked bags are assumed to weigh 25 pounds each. Some airlines that fly small planes with 19 or fewer seats have already raised their weight allowances by about 30 pounds, the F.A.A. said today.

## 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.

## Do they weigh planes before takeoff?

The aircraft is not weighed for each takeoff, still it has been weighed to determine its basic empty weight and its center of gravity. This operation must be done every 3 or 4 years (9 or 18 years in a large fleet, this is a specific process) according to JAR Ops 1.605, Appendix 1.

## 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.

## How do airlines calculate weight and balance?

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. Divide the total moment by the gross weight to find the center of gravity.

## Can I buy 2 seats on a plane for myself?

## 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.
