Ground Support Equipment (GSE) refers to the various tools and machinery used to support the operations of aircraft while they are on the ground. This includes equipment for fueling, baggage handling, maintenance, and passenger boarding. GSE ensures that aircraft are ready for takeoff and can be efficiently serviced between flights. Common types of GSE include tugs for towing aircraft, fuel trucks for refueling, and baggage carts for transporting luggage. Proper use of GSE is essential for maintaining safety and efficiency at airports, helping to minimize delays and ensure smooth operations.
