(My english is not very well, so I used some Google translate):
The behavior of AI is very variable and as I have been trying, with small changes they improve a lot. Although also those changes it definitely does not improve and I choose to change their position (and they improve).
Example 1: In my case, it has been complicated to get many planes to take off from an AF. If I put several AI on runway and some in parking, those who start from the parking lot, usually hit each other before reaching the runway because the first group has not taken off completely. If I give them too much time between one group and another, the mission becomes very slow to continue. And sometimes the second group never takes off, and sometimes, yes.
Example 2: Even if I manage to give them more time between one group and another, the group that take off, if they are numerous, 2 or 3 AI skid and goes off the track. In some cases I have solved it trying to place the VPP as much as possible inline and in the middle of the group. A small movement of AI during take off can generate an exit from the runway in some cases.
Example 3: Moving around the track from the parking lot: Placing many taxi points generates a slow AI. Place taxi point on the edges of the track, make them get out.
Many details that cause good improvements in AI and that sometimes we do not consider them.
In others, I simply have not been able to solve it. For example, I can´t achieve a good takeoff from a group of 12 HS129. Always 1 or 2 skid and leave the track. Finally I had two possibilities, reduce the number or place them in flight and it is solved. However, if I change them for 12 figther (109), no problem occurs. Maybe the issue is because this group is composed of groups of 4 squad each, and they have different waypoints). It could be solved if the 12 AI are in a single squad...maybe...I have not tried it yet. Or the other solution could be: first group after takeoff, enable the second, and the second after takeoff, enable the third. So no group influences each other on the runway (I have not tried that either, I'm thinking as I write).
And it is true, to achieve a good AI behavior, it requires a lot of tests (luckily there is the option "accelerate the mission"). I also test only the maneuver I want to try apart (new file). So I do not need to do the complete mission. And when it's OK, I add it in the general mission.
Each mission of the campaign that I am creating is checked several times. When I finish it I will need some Testers..... many eyes see better than 2.
