Fuel Savings
When aircraft taxi using their engines, they consume significant amounts of fuel.
A typical 737 will consume between 17 and 25 pounds/minute while idling.
WheelTug, by requiring only APU power for taxiing purposes, can cut that
fuel cost substantially. With a typical 737, fuel savings of between 13
and 21 pounds/minute of taxi time can be expected.
This not only saves fuel, it can cut the amount of fuel required for
unexpected ground delays.
On typical short to medium-haul routes, these aircraft spend a significant
percentage of their time on the ground - these savings can really add up.
