When can the space between an aircraft and terminal building be used as a vehicular route?

The space between an aircraft and the terminal building can be used as a vehicular route specifically for vehicles servicing that aircraft. This practice is critical for ensuring safety and efficiency on the airport ramp. When servicing an aircraft, including fueling, baggage handling, or maintenance, dedicated access routes are established to facilitate these operations without endangering personnel or equipment.

Using this space for other vehicular traffic could create hazards, as it is designed primarily for the operations directly related to the aircraft. Allowing only service vehicles maintains order and minimizes risks associated with mixing different types of vehicular traffic, which could lead to accidents or delays. Therefore, limiting access to service vehicles ensures that those directly involved in the aircraft's operation can perform their duties without interference.
