This is stock SimpleAirways with Vizzy landing program v3.0, delivering major algorithm improvements. Notable changes since v2.0:
- not only the Classic Juno System runway can be chosen, but also any of 4 runways in new Juno System on Droo
- auto-throttle (in phase2) and better flaps handling
- throttle logic not only controls velocity, but it also helps to maintain correct pitch if needed
- new landing trajectory - the craft tries to keep about 5% descent slope before touchdown (in v2.0 it flew very close to the ground)
- generally much better navigation/avionics: it finally converges to desired trajectory in a stable way, with quite good precision
- now it is stable on mobile (but developed and tested mostly on Steam version)
- it reduces vertical velocity just before touchdown to make it soft
- improved status display: in particular, there is approximate ETA (only in phase2)
It works on mobile, but you must ensure you have at least 10 (preferably 20) FPS by changing quality settings. Physics should probably be at High.
Limitation on initial position: if you project your position on runway centerline, the projection point must be some distance from runway, cause the program uses centerline as X axis along which it measures distance.
How to use: while in flight, enable "Landing autopilot" AG, enter runway number you want to land at, unpause game (you may be asked for desired throttle if very far from runway) and enjoy your flight.
AGs: 3 - engines, 8 - landing gear, 9 - landing autopilot.
Landing velocity on touchdown is typically about 110-120 m/s and vertical velocity about 4-8 m/s.
For more details see older versions of this craft.

I want to make final approach more long because mobility of my craft is not good.
please tell me how to change cord. -

@analyzer1 I figured the code was pretty specific to the 747 for the reasons you mentioned. instead of making custom code for each craft, perhaps the important variables (thrust, weight, drag, etc. etc.) could be entered by the user to make it work? I tried the program on the large Super Albatross and although it did it's best, the best didn't land with enough room before heading over the cliff. Running it on a smaller craft was way worse, correcting and over correcting until it finally struck the ground long before reaching the runway.
If you wanted it to try a different large plane, look for my craft "The Tommy Bomber". I'd be interested to see how it would land after dropping about 430,000kg of bombs. Take off weight is about 1,208,000kg, but after bomb drop the landing weight is 778,000kg. I don't know how that would affect the landing code.
Still, very cool programming! -

@kittman The code is written as generally as possible, but nevertheless it has some values, like PID coefficients, tuned specifically for 747, the stock one. I've just tried another stock SR2 airplane: Wasp 2.0. It's much smaller... and that makes a difference. With my autopilot it was banking aggressively from side to side, making turns impossible. It finally landed on the ground, quite far from runway. Finally when reverse thrust was supposed to be enabled... it enabled thrust, but forward! Seems like reversers are not tied with braking and that should be easy to fix. For the banking, I'll try decreasing roll coefficient in my program. So generally, it needs some tuning for each craft, because aerodynamics of each craft and other properties, like moment of inertia, max thrust, are different. I doubt a generic program could be written. I'll check later some other heavy craft - I believe it may work well for "passenger jet" airplanes.

@analyzer1 This works great! i'd love to see it work on different planes. is the code tied specifically to the simple airways 747? i'm gonna try it on a somewhat smaller cargo plane and see what happens...

@kittman You liked the previous version, perhaps you would like to check this out too :)
BTW This version is so well tested on SimpleAirways, maybe I should finally test it on some other aircraft.

41 Downloads and nothing? people are you kidding? it works perfectly! Once you click on the download, can you click on the upvote? 👎👎
Does anyone have experience with calculating the distance traveled (odometer) and if it can be done in the vision, I would need help
