If set to yes, VehicleTypes are able to dock with this structure and get repaired. Repair rate and cost is determined by the [General]→URepairRate= and [General]→RepairStep= flags.
In unmodded RA2 and YR, this flag is commented out from the entries for the Allied Airforce Command Center and its American equivalent, along with a comment ;gs this is part of reloading + being an aircraft (Repair code is oogly, only Reload got rewritten for four ports.).
The comment fails to mention any bugs, but reenabling it on such a structure will have adverse side-effects and even cause an Internal Error - when an AI's unit is damaged, it will attempt to find the closest structure it has with this flag enabled (regardless of whether the unit can actually enter it), and send the unit there for repairs. If that destination structure happens to be an airpad, the game will enter an infinite loop and crash.
In addition to this, even aircraft that can legitimately land in this structure will trigger its repair loop after landing, and this loop will kick them off once they're fully repaired, meaning that an aircraft sent to dock with such a structure will never manage to do it.
