posted an idea a while ago here:

My “little” strategic radar idea for Aces High.
This is a multi-tired way of arranging the radar. The hierarchy would be Base – Zone – Country.
Starting at the top, HQ, radar information is transmitted across the map. HQ no longer becomes an actual radar facility, but a communication headquarters. There would also need to be a communication strategic target in each zone. The last component would be radio communications at the individual bases.
Here’s how the system would work in a whole. Radar from the individual radar domes at the bases would be a local system, visible to the planes who took off there. This radar of course could be destroyed, possibly a facility a short distance from the base, and possibly 1000 lbs to destroy it (or more). There would also be at each base a radio communications tower. This would be destroyable also; similar to the radio looking tower we have now.
If functioning properly in an entire country the radar would be mainly seen by all. The individual bases would relay their radar information to the zone communication strat. That strat would then relay that information to 2 places, HQ, and the other bases in the zone. HQ would then relay that information to the other zone communication centers. These communication centers would obviously relay the information coming from other zones.
In the below example I have made, I will explain how the system would work.
Bases 1, 2 and 3 are in zone 1. Bases 4, 5, and 6 are in zone 2. Bases 7, 8, and 9 are in zone 3.
The current statistics of the map below are as follows:
Bases 1, 2, and 3 are full up, but the communication center for that zone is at 50%.
Bases 4, 5, and 6 are full up, and the communication center is full up.
Base 7 has radar down. Base 8 has radio down. Base 9 is full up. The communication center is fully down
HQ is full up.

From this information I will explain how it all works. Player A takes off from base 2. On the clipboard map, this player sees the DOT radar blips for all the bases in the zone. He also sees the BAR radar for all the bases in his zone. He also sees friendly and enemy BAR radar for the map, but does not see any friendly or enemy DOT radar outside of his zone.
Player B takes off from base 4. He sees both DOT and BAR radar for all the bases in his zone. He sees no radar information for the zone with bases 7, 8, and 9. He does see BAR radar for the enemy, and for the sectors in the first zone.
Player C takes off from base 7. He sees the DOT and BAR radar for his sector, and that is all because the communication center for his zone is down. He does not see any DOT or BAR radar for the rest of the map.
Once the communication center for the 3rd zone is back up, player C can see DOT and BAR radar for all of zone 2, and base 9. He can only see BAR radar for base 8, as the radio tower is still down.
For all of these examples that base you take off from is the basis of your radar updates. You can fly across the map, but you are still tied to that base. If you stop and reload at a different base, you are now tied to that base, and zone, and receive radar updates accordingly. This could possibly be modified to what airspace you are in. if you flew too far into enemy territory (3 – 4 sectors maybe) you would not see any radar on your map.
How does HQ work into this?
Considering all strategic communications centers are full up, and all bases are full up, if HQ is 50% damaged you will not see DOT radar for other zones, only the zone you are in.
If HQ is fully down you see no enemy BAR radar and no radar at all from zones you are not in. when I say enemy BAR I mean across the whole map.
The advantages of this would be strategic warfare across a front, and more of a meaning to communication. The realistic part of this is that in WWII they didn’t have up to the second reports on what was going on. We have to make some game play concessions, so we still get radar updates. If the lines of communication are broken though, we have to deal with what we have.
If I have missed an example, please ask, I can easily explain what the situation would be in the game.
