Formation Autothrottle

Just select your target plane / tanker as an Air-To-Air target and hit ag2. Throttle as well as airbrakes are automatically active.

Controls become less sensitive as you approach your target so use trim!

Default distance = 35 meters
VTOL up = 55 meters
VTOL down = 15 meters
It will probably be a bit farther tho

Approach from behind the tanker. If you get ahead of it, disable ag2 and brake until you are behind again. Works with any tanker speed but I usually run at max, controls are more crisp.

Also try not to move side to side too rapidly or it will mess it up.

    I guess this is becoming part of my wasp autopilot demos series lol. Let me know what else you want to see me force the plane into doing for you!

    Btw my Citation has autothrottle added into the approach codes. It slows down as you approach the airport. Also a very primitive automatic flare, despite being unrealistic for the CJ4

    @Rjenteissussy lol but I have trouble to refuel even with this. I am a noob 😅

    @OrderlyHippo it’s because they want to churn out the best pilots on the earth rather than the best autopilot operators haha

    Kind of like the explanation for top gun, where they are trying to teach strategical dogfighting tactics rather than using long range missiles and just relying on having bigger engines and better g suits

    @pilotman10 yeah that one doesn’t even come close to working for me sorry

    @UltraLight Oh. I thought you meant automatic flare as in shooting flares automatically. Sorry 😅. I always wonder why the air force doesn’t use an auto throttle system like yours for refueling

    @UltraLight the user called @Huax did an automatic refuwl plane but too many parts subassemblys and variables you cant copy that on mobile sadly so you could look on his build for a solution

    @ReturnOfJeffChandler ok lol great...
    1. Terrain avoidance is impossible because there is no radar -- just the AltitudeAgl but thats just directly under your plane
    2. Wing flex is REALLY commonly used by the airliner building section of the community, so I'm not gonna pretend I invented it lol
    3. High Alpha, Stall Recovery, etc is GuyFolk's stuff. Talk to him
    4. Auto takeoff? Push the throttle to full and set trim to the bottom lmao
    5. The waypoint thing is a fun idea but also VERY simple. Just plug a trig expression into a heading hold expression. I can explain it to you and you can probably do it yourself.

    @OrderlyHippo just an increasing pitch input as your AltitudeAgl decreases. It is very rudimentary and relies entirely on the perfection of the glideslope and autothrottle. Hopefully one day I can sit down and really make it work, coding to maintain a vertical speed which decreases until 0 as you touch down.

    @pilotman10 I tried that. The issue is that the data on target elevation and heading is vector based, so as you get closer it becomes more sensitive. So as you get closer, the oscillations get very bad and the autopilot loses stability altogether. Plus, the accuracy necessary to capture the drogue is insane. So I guess you're stuck with hand-flying for now.

    @TRD yep! You may need to adjust the gains a little but just copy the variables over!

    I love how it enters hyperdrive if you get ahead of the target

    •Automatic Terrain avoidance like the F-111, •oooh also add an automatic intake system
    •Wing flex
    •High alpha
    •Coordinate flight computer for plane to follow way point
    •automatic stall recovery
    •automatic takeoff
    •automatic fuel dumping (maybe idk)
    •so on the list goes on

    Automatic flares? How?! @UltraLight

    Can you then make that it will also fly automatically behind the drogue of the tanker for refill

    Okay, soo... can this system be applicable on any plane?
