AtmosphereAutopilot plugin I'm a flight man. After getting bored from mundane KSP launch routine I found myself enjoying my old hobby - atmospheric flight. And then the struggle was born - lack of control. SSTO's were annoying, keeping them on ascent was hard. Flying anything but overdamped dart was exhausting even with joystick. I felt like i'm in 1940-s, and it was not the feeling i wanted to get from a game I love so much. One year ago, in November of 2014, I started working on this plugin to solve those problems for me. I needed three things in my life: generic fly-by-wire, cruise control and automatic lander. It makes me sad, but after one year, I only managed to implement the first autopilot (cruise control is also implemented). Considering my free time shortage as a student, I decided to still release this mod here, for one may find it's functionality useful for him, or for another to see the potential in this mod and help it with his advice or coding\engineering skills. Autopilots list: Standard Fly-By-Wire. Control signal abstraction autopilot, SAS replacement. Here is a short flight footage of statically unstable plane I took: VIDEO. You can see roll-yaw induced isolation, AoA and G moderation, as well as general behaviour of the autopilot. Mouse Director. Plane tries to fly towards camera direction. Use middle mouse button hold + mouse turn to look above the craft and have a convenient camera angle. Precise control (CAPS LOCK) prevents from roll-over while accelerating down, as well as restrains acceleration in general. VIDEO. Cruise Flight. Maintain course, altitude, speed, fly towards a waypoint, picked on Kerbin in map view by click. More details in documentation. Videos: Quick overview by KerbalItalia dude (in Italian of course, but that doesn't really matter): https://youtu.be/k3rLK4uuJg8 F-35 post-stall piloting with FAR (no commentary): https://www.youtube.com/watch?v=Gi-zXRDfyAs Download links: SpaceDock or Github As usual, put .zip contents in gamedata. License: GNU GPL v3. The KSPUpgradeScriptFix.dll and its source can be found on this post (link for convenience) (alternative: https://github.com/net-lisias-ksph/KSPUpgradeScriptFix). Dependencies and compatibility: You'll need ModuleManager. FAR is supported. No wind mods are supported, as well as any mods, wich are changing control surface, rcs and engine gimbaling behaviour. I recommend using Kerbal Joint Reinforcement by ferram4. If you're using "Stock Bug Fix Modules", turn off ModuleControlSurfacePlus and ModuleGimbalPlus modules in it's manager. FAQ: >FAR? - yes >My control surface settings are not respected - Make sure you reconfigure your crafts (set pitch, roll, yaw again) after mod installation, if you're using stock aero. You will not have to do that again, unless you delete the mod. >Wobbling on my plane. - yes. In 99% of cases I'll know what's the problem, it's just that to fix it would be impossible under my time budget. Warm it up by pitching\rolling, tweak some stuff, it may help. Ask me, if desperate. >How to make the plane follows surface-level pitch, instead of orbital, while using fly-by-wire? -Put navball in surface mode. >AFBW mod is not cooperating with the standard fly-by-wire. -Activate "AA compatibility" in AFBW's GUI. Documentation: I tried my best at providing documentation of the code itself and writing a readme you can find in the archive, or in Git repo - https://github.com/Boris-Barboris/AtmosphereAutopilot/blob/master/README.md. Please, make sure you've examined it before asking any questions. I'm not very good at support, but i will try. FPS impact: Computational complexity of plugin (when active) - O(n), where n - number of parts. You will feel it on 100+ part crafts, and you will feel a heavy GUI, wich is full of numbers (Unity is slow with rendering strings, or maybe I'm just a bad coder), needed for debugging. Fortunately, most of the time, you don't need any GUI at all. Hotkeys: Default ones: "P" - "Master switch" you can use to toggle AA. "Shift"+"P" - toggle Autopilot Module manager GUI. "O" - default hotkey for moderation switch, when Fly-By-Wire is active. Can be changed in Global_settings.cfg in Fly-By-Wire section. KOS integration: Acknowledgments: Sarbian - for support of ModuleManager and consultation on numerical precision issues, and other cheesy KSP stuff. Kobymaru - he kindly helped with initial criticizm and debugging of plugin in August-September. Ferram4 - for providing a license application example to copy from, I'm new to this stuff. Morse - neo-GUI design and implementation. Hotel26 - multiple UI-related additions.
