Just to add on to No Idea's posting"
When this game first came out it was quite possible to wipe out the entire Soviet air force. In the campaign game players could kill 10,000 aircraft. The first change to rule 16.3.1 was in 1.05.42 with a constraint of 50% of the FIRST miles flown to participate in a DAYLIGHT airbase attack. The next change was soon after in 1.05.53 to limit a DAYLIGHT airfield attack to the FIRST
1/3 miles flown. (2012)
So the optimization of bombing airfields is very nuanced .. in fact letting the AI attack can have better results than a player because of these nuances.
That said ...
A very key rule is 16.1.3 "Air Mission Staging Bases. The air groups will fly to a staging base and then to a target with the staging base extending the overall range of the planes while reducing miles flown (Very important due to rule 16.3.1). So one has to use staging bases. A staging base is simply a base closer to the target than the base holding all the planes you want to use. But wait! Why not just move an airbase closer to the target? That is much more simple ...
When you move an airbase full of planes 3 bad things happen ..
1) Fuel is used up in the movement .. planes use fuel to fly
2) Miles flown go up with the movement .. it is assumed that the planes fly to the new destination
3) Not to add to the plithora of details but moving things full of things in this game uses trucks .. you need trucks .. just remember that ..
So not good to move airbases full of things .. have to reduce miles flown -- particuarly the FIRST miles flown
One other constraint .. a mission can consist of only one fliegergroup (My Axis bias here Soviet has an equalvalent)
So the intial base, and staging base have to be from the same FLG
Also ... the airbases that belong to Army and pz groups are for RECON only so moving a army group base will not help you bomb airbases
Now how to clean out an airbase so you can move it to the front line with minimal truck use ..
Air transport planes from a base with few aircraft to another base from the same FLG . Now with that base empty you move it closer to the front lines where you will limit your miles flown.
We have bases with bombers and fighters and we have moved a staging base closer to the front line in clear terrain. Now one can shift right click over the target and get a list of aircraft .. the AI is not so smart in picking optimal staging bases .. so first left click an optimal staging base .. then over the target shift right click .. click the appropriate planes for the mission.
Now another nuance ..the list will only pick the first 14 air groups .. you might not want those planes for that particular target. So ..should you be Daylight bombing ...switch groups you do not want to fly to night. Now the list picker thingy will exclude those planes.
One other important nuance of this game .. you will eventually want to fly aircraft from bases closer to the front lines. It behooves the player not to just roll everything up closer as stated above. But those forward staging bases can be placed next to a rail head in clear terrain and planes flown forward. Then the bases in the back become staging bases while those forward bases become the holders of terror ...
Now you asked "why cant I use a templete or guide and achieve the same results .. " As you can see there are lots of nuances and there are rules changes since these templetes have come out ..I have just touched upon three very important concepts that these "guides" do not mention.
I suggest to read AAR's .. especally the newer ones.. Here is my AAR
tm.asp?m=4360475 look at posts #11 and #20-26 for pictures showing an optimazation of air power. The picture in post #11 shows just how far airpower can project using a staging base ...
