It begs for a sandbox test in the editor with two isolated
islands - A with 100% damaged airfield and B with aircraft and supply. Maybe someone can help?
Any unit can repair runways (but engineers are best of course), but the Airfield Service component needs engineers.
Did you observe any increase to delivered supply from the aircraft? (don't know how it can be separated from normal supply unless the AF usually gets supply once or twice a week and you did the test in between deliveries.)
