A/C (or AC)

A/C in aviation means aircraft, and it encompasses all flying machines used in air transportation, both personally owned and those designed to carry passengers.

Commercial aircraft are divided into two main types: narrow-body and wide-body. The narrow body features only one passage or pathway and is used for short travel, primarily for local trips.

The wide body is designed with two pathways or aisles that can travel long distances and can transport up to 850 people at a time.

AOG

Another aviation terminology abbreviation is AOG, which means Aircraft on Ground. This abbreviation indicates that an aircraft cannot operate as it usually does or take off due to specific issues.

The issues can be unfavourable environmental conditions or other technical problems. However, in a situation where an aircraft is grounded due to a mechanical issue, it needs to be properly repaired, examined, and authorized for usage.

MRO

This means Maintenance, Repair, and Overhaul, and it is used to express the three crucial services that guarantee the effective functioning of the aircraft.

Maintenance refers to the periodic check-up given to an aircraft to ensure that its systems consistently remain in good condition over its lifetime. Repair means the fixing of a part, unit, or system within the aircraft to restore it to its good working condition.

During an overhaul, critical aircraft structures are selectively removed, thoroughly inspected, and treated as required, following the Original Equipment Manufacturer (OEM), Component Maintenance Manual (CMM), and other relevant requirements.

IATA

IATA stands for International Air Transport Association, and it is the international airline trade organization. It was established in 1945 to provide regulations that ensure the protection, effective performance, and security of aircraft operations.

AO

AO is used to express an air operator, and it means an individual or organization that owns, manages, or operates an aircraft. As such, they are required to obtain an Air Operator Certificate, which provides guidelines to ensure safety and remain in compliance.

ACMI

ACMI stands for Aircraft, Crew, Maintenance, and Insurance. It is used to describe a type of rental arrangement between two airlines.

Usually, one of the airlines provides the other with an aircraft, crew, or staff, maintenance, and insurance. The other airline, known as the lessee, pays the lessor depending on the timeframe during which the airplane was flown.

This type of arrangement is primarily used when an airline requires additional airplanes for various reasons, and it’s commonly employed for both passenger and cargo travel.

GSE

Ground Support Equipment, as its name implies, refers to all machines and equipment used in handling and aiding aircraft while on the ground. It includes tow vehicles, pushback tractors, and other equipment.
