Comat – Company Materials

8 Airline Cargo Terms you Need to Know

Company Materials (COMAT).

Company material, commonly called COMAT, is an industry term used by operators to describe the shipment of non revenue (no freight revenue or compensation received) materials and supplies owned by the operator that are shipped by the operator in support of its operations. Aircraft parts owned by the airline shipped from one city to the next for repair of an aircraft would be considered Comat.

Hazardous Materials (hazmat)

Materials or substances meeting the definition of hazardous material in Title 49 of the Code of Federal Regulations (49 CFR) part 171, § 171.8

First Article Inspection

. Inspection of the first of a manufactured component to ensure compliance with certification and airworthiness requirements.

Interlining Cargo

Transfer from one operator to another, whether the same or different aircraft types are used. For example, a ULD transferred from a domestic operator to a foreign operator.

For the purpose of this AC, cargo refers to passenger-checked baggage, freight, Company Materials (COMAT), special cargo, and hazardous materials (hazmat). Cargo does not include passenger carry-on baggage.

Active Unit Load Devices (ULD)

ULDs with active temperature control systems for transporting temperature-sensitive cargo. These systems consist of a highly insulated container with a battery-operated heating/cooling system integrated into the construction of the container. Active ULDs are intended to be operating during flight. Active ULDs are battery-powered in flight and are only recharged while on the ground. The “active” component of these units typically consists of a vapor cycle refrigeration/heat pump type system that is powered by various types of large batteries, depending on the manufacturer.

Aircraft Loading Schedule

The loading schedule is used to document compliance with the certificated Weight and Balance (W&B) limitations contained in the manufacturer’s Aircraft Flight Manual (AFM) and W&B manual (WBM). The loading schedule is developed by the operator based on its specific loading calculation procedures and provides the operational limits for use with the operator’s W&B program accepted under  AC 120-85A  

Load Supervisor

An operator-determined name, such as loadmaster or load lead,
identifying the job function of the person with overall responsibility for supervising the loading
of the aircraft. This person is responsible for signing the load manifest. Refer to Title 14 of the Code of Federal Regulations (14 CFR) part 121, § 121.665, Load Manifest.
