mass and balance ( chapter 5 > required skills and knowledge )

Three main methods of carrying cargo are

1. Containers

2. Pallets

3. Loose ( bulk cargo restrained by nets )

Unit load devices ( ULD ) are

1. Containers

2. Pallets

Advantages of using containers are

1. Quicker to load aircraft

2. Less effort to load aircraft

3. Direct interface with the aircraft’s loading and restraint system

4. Protection of cargo from damage

5. Each container has its own manifest, allowing easy tracking contents

The three limitations on cargo mass are

1. The maximum allowable total cargo mass

2. The maximum area load limit

3. The maximum linear load

ULD’s are secured where

Inside the fuselage on latches within the rollers and tracks

Bulk cargo is restrained by

Nets, attached to attachment points and tie down points

Area load formula is

Area load = mass divided by area

Linear load formula is

Linear load = mass divided by length

Area load units are

1. Kilograms per square unit

2. Kilograms per square foot

3. Pounds per square foot

Linear load units are

1. Pound per inch

2. Kilogram per inch
