Post subject:  Anti Aircraft attacks

I had a closer look at the Anti Aircraft rules and found a pattern.

Weapons which are capable of an AA attack are modified in this way:
- Aircraft mounted with Fixed Forward Arc: no change in range, weapon has only AT then AT = AA attack,  weapon has only AP then AP+1 = AA attack, weapon has AP and AT then AP = AA attack.
- Aircraft mounted with Front/Left/Right/All Around Fire Arc: Range -15cm*, weapon has only AT then AT = AA attack,  weapon has only AP then AP+1 = AA attack, weapon has AP and AT then AP = AA attack.
- Ground unit mounted with AA-mount: Range -30cm**, AT = AA attack.
- Ground unit mounted without an AA-mount: can't shoot at Aircrafts.

* Explanation: The gunner is concentrating on a wider firing arc.
** Explanation: The gunner is conentrating on a wider fire arc (the whole sky! = 360?) and Aircrafts are flying high which increases the range a projectile has to travel.

So i came up with the following proposal for how ground units can shoot at aircrafts:

Anti Aircraft Attacks from ground units
All units can use the shooting part of their action to fire at Aircrafts with their AT or MW shooting attacks but have to substract 30cm from their range and only hit on a 8+ (a 6 followed by a 5+)no matter what the actual to hit value is. Crossfire can?t be applied against Aircrafts.
Units with an AA attack are assumed to permanently screening the skys for enemy Aircrafts.
Use the rulebook rules to determine how and when an aircraft can be attacked by ground AA-units but they substract 30cm from their range, too*.
If the AA-unit fires their AA-weapons on ground targets it can't use this weapon to fire at Aircrafts for the remainder of the turn because the gunner is concentrating on ground targets and can't simultaneously look out for enemy Aircrafts. Otherwise an AA-unit which has already fired on Aircrafts can't shoot at ground units for the remainder of the turn.
Example: A formation including a Hydra is attacked by Ork Fightabommers. The Hydra fires at the Fightabommers and shoots one up. Later the Hydra's formation fires at an Ork Warband. The Hydra can't join in to blast some greenskins because it already has fired against Aircrafts and is assumed to watch the skies.

*This assumes that all weapon ranges of ground based AA-capable-weapons are increased by 30cm. For Example a Hydra would be able to fire up to 75cm against ground targets and 45cm against Aircrafts.
