Approach/Departure operations for KDAY were consolidated into the Columbus TRACON quite some time back. We have recently made that change here at ZID. When arriving/departing the Dayton Airport and airports in the surrounding area, contact with the Columbus APP/DEP controller, if online, should be expected.
Calm Wind Configuration is runways 24L/R. This configuration is used up to and including 10kts.
Runway 24L typically departs south and east, except larger aircraft requiring a longer runway.
Runway 24R typically departs north and west.
