This is more something that would be useful for FSO, Scenarios, etc., but in the last version of Air Warrior fields would have names rather than numbers. In AWIII these were usually named for staff members or noteworthy players of the past.
Something like this could be used in historical setups to help with the immersion factor.
Like, instead of C76 you're taking off from USS Intrepid. Or A1 may instead become Henderson Field, etc. Granted such names could be designated in the orders, like in this month's FSO, but it'd be great to have them actually built in to the maps.
