TIM = Operating Time-in-Mode. Bold font = suggested default GSE fleet mix and TIM. *Cabin service and catering trucks are separate in AEDT. Fuel and hydrant trucks are separate in EDMS. TIM represents average between the two. **Service Truck includes all service vehicles, including minivan. ***Gate-only observations. Final recommendation for baggage tractors is higher (based on airport size) to account for the time it takes to travel to loading/unloading area. Final recommendation for APUs is higher (based on airport size) to account for taxi-in and taxi-out times.
