It's long bugged me that in so many instances AI will inexplicably stay with clearly disabled planes all the way to crashing. One particularly egregious offender is the Wildcat. It seems the aileron controls are quite prone to being hit--as you'll see below. The stock treatment caused the pilot to ignore his impending doom, and legion are the instances where I've watched the idiots meekly stay aboard their crate as it slowly spirals to earth with disabled ailerons.

For the three control surface systems, aileron, elevator and rudder, AircraftState.doSetControlsDamage() renders the control ineffective, which can lead to a crash. Unless some other triggering event causes a bailout, the AI sticks with the crate no matter what.

I've expanded upon the method by adding conditional checks (with some randomization) by which to cause a bailout. I include two output runs to check on what the code is doing. This output goes to log.lst (via the temporarily active System.out.println() commands). The mission is my 9 Zeros vs 12 Wildcats, where  I knocked down the vast majority. The enemy are identified by their assigned number and an asterisk (no asterisk present denotes a friendly). Note that there can be multiple instances of the triggering event, depending on how much I'm pummelling the crap out of the victim. A "hit" event identifies the stock result; the "----bail" events are the result of my new code. Previously, no bailout would have been commanded.

Different planes can have vastly differing 'sensitivity' to controls damage. As noted, the Wildcat has particularly easy-to-hit aileron cables. Some planes can be blasted to bits in great numbers with few or even no triggering events!

In the end, I'm rather liking the reduction of instances of AI drones mindlessly going down to their doom with dead controls, now having them rather more likely taking to their 'chutes.

STOCK AircraftState.doSetControlsDamage()

I appreciate you taking care of our doom fated AI companions

[Whiskey_Sierra_972]

That's a revolution!

Infact I suspect that if you cripple an AI plane to be certain of it's crash BUT AI doesn't bail out , if you finish the mission with it still in air , you'll never got the kill credit....

[Cycle]

Great, Tech! 
There is another thing that I associate with this topic and that is the landing priority of damaged AI aircraft. Just a thought for the Future..

[WxTech]

The stuff I'm dealing with here is really simple, triggering a state based on an event.

Getting into the decision tree structure of AI proper is a whole other ball o' wax. 

[Cycle]

Yes, of course! I'm just happy that someone is working on AI behaviors like this!

I just think out loud for a moment:
I've played many DCG campaigns over the years and have often observed damaged aircraft from both sides!
Many of them crashed near their home bases or aircraft carriers because, despite their damage, they were forced to fly circles many times!
And some of the damaged aircraft collided with other aircraft due to the different speeds.

First, check how many engines the plane has and how many of them are damaged!
The other thing would be whether the plane currently has fuel leaks and how much fuel is still available for the plane when the AI asks for a landing!
Not the number of fuel leaks or injured crew members on board!
I think that would help a lot.

[raf1659]

Fantastic! 
When will we be able to see this innovation in B.A.T.?

[TXZCJSP]

Does it support non-BAT modules?

[WxTech]

This can be adapted to any game version.

Even ModCat?

Even ModCat?

Out of topic I was curious to have a look at ModCat mentioned in a video of Mr.Fresh do you know where i can find it;
