I have always thought of creating a Test and Training Range on the Marianas map dedicated in particular to air to ground.
There are several aircraft available that you can use, in particular:
F / A-18C, F-16C, A-10 II, AV-8B, Mirage 2000C and also Apache helicopters.
The Shooting Range was built on the island of Aguijan and you can choose which type of land unit to attack, just select it in the F10 menu of the radio under "other".
In addition to the TTR to use with your multiplayer flight companions, you can use the map for many other situations, even to fly alone and practice refueling in flight, or landing on the Truman aircraft carrier.
I hope I have done a good job and above all something useful for everyone to learn how to fly on your favorite plane.
