What does "ground support equipment" include?

Ground support equipment refers to a variety of tools and machinery used to support the operation of aircraft while they are on the ground, rather than in the air. This includes equipment like tugs for towing aircraft, fuel trucks for refueling, and baggage carts for handling luggage. The primary purpose of this equipment is to ensure that aircraft can be efficiently serviced and prepared for takeoff and landing.

The other options do not align with the definition of ground support equipment. In-flight entertainment pertains to systems used during flights to enhance passenger experience, runway maintenance involves equipment used to keep the runways in good condition, and personal protective equipment is focused on ensuring worker safety. These categories do not relate to the operational support functions aimed at aircraft while they are on the ground, which is why they do not accurately describe ground support equipment.
