Phoenix Logs/UNSC Buildings/Airpad

From Halopedia, the Halo wiki

Airpads are firebase support structures that allows the requisition of Hornet, Nightingale. and Vulture flyers from the Spirit of Fire and unlocks their upgrade options. Multiple Airpads in a firebase reduces flying vehicle requisition time.

Expeditionary airpads house the maintenance crews and equipment needed to assemble, repair, refuel, and rearm UNSC aircraft. Airpads also support the force commander with sensor feeds and intelligence uplinks which allow for proper battlespace deconfliction, kill chain assignment, and other aerospace management tasks.
