System Notes

GSE stands for Ground Support Equipment, referring to all the machinery and vehicles used to service aircraft on the ground, like baggage tugs, pushback tractors, and jet bridges, with a dedicated team of mechanics and technicians (GMMs/GMTs) responsible for their maintenance and ensuring efficient, safe airport operations. 

What GSE Includes:

  • Vehicles: Baggage tractors, belt loaders, aircraft tugs, de-icing trucks, and passenger stairs.
  • Stationary Equipment: Jet bridges, ground power units (GPUs), and air conditioning units for aircraft.
  • Support Systems: Fueling and lubrication systems for the equipment. 

The GSE Team's Role:

  • Maintenance: Performing heavy maintenance, routine checks, and repairs on this vast fleet.
  • Operations: Ensuring equipment is available and functional for quick aircraft turnarounds.
  • Sustainability: Modernizing equipment, such as transitioning to electric GSE, to reduce emissions. 

In essence, the GSE team keeps everything without wings running smoothly so the airplanes can take off and land safely and on time.

Ramp Operations

Implementation of additional digital tools on the ramp has reduced radio traffic enough to consolidate smaller zones in councourses A and B into two larger zones in each concourse. Deprecated zone channels have become alternate channels as shown below.
