Auto Credit Based on klm747klm747's 757-212GS
Only the left side of the aircraft is accurate. DOES NOT FLY.
VTOL Down+ AG1 = Flaps and Slats
VTOL Down+ AG3 = Spoilers (they also work with aileron)
If you retract the gear, you may notice the automatic timings on the gear doors, with only ONE ROTATOR.

@klm747klm747 Can't wait to see it!
@EpicPigster1 @Omel
RIP AA757 1989-2020
@EpicPigster1 thank you!
@klm747klm747 jesus christ that's actually nuts, that's a lot of code. Bravo man, i'm gobsmacked, amazing!
The autoland and autotakeoff code, simplified, is
clamp((clamp01(Activate7)(clamp(((clamp((((PitchAngle)+(-12))/10), -1, 1))clamp(((TAS)+(-64))/(12.5), 0, 1)+clamp(((Trim)/(2)), -0.5, 0.5)), -1, 1))+clamp01(Activate5)(clamp(((PitchAngle+ -5)/5), -1, 1))-(clamp01(Activate5)clamp((((AltitudeAgl / 10)(-1))+2), 0, 1.2)clamp01(((AltitudeAgl)*(-1))+(20)))), -1, 1.5)
@Omel Definitely
@EpicPigster1 OK so I'll explain
_
_
First Rotator: clamp01(Activate7)(clamp(((clamp((((PitchAngle)+(-11))/10), -1, 1))clamp(((GS)+(-68))/(12.5), 0, 1)-clamp((RollAngle)/(15), -1, 1)+clamp(((Trim)/(2)), -0.5, 0.5)), -1, 1))+clamp01(Activate5)(clamp(((PitchAngle+ -3)/5), -1, 1)clamp01((AltitudeAgl)+(-28)))+((clamp01(Activate4))clamp((((Altitude)+(-1524))/50), -0.5, 0.1))+clamp01(PitchAngle+ -15)/5
_
The only important part is: clamp01(Activate5)(clamp(((PitchAngle+ -3)/5), -1, 1)*clamp01((AltitudeAgl)+(-28)))
_
clamp01(Activate5)
Only allows the system on when AG5 is on.
_
(clamp(((PitchAngle+ -3)/5), -1, 1)
Wants the aircraft to maintain a 3 degrees nose up angle in the descent.
_
clamp01((AltitudeAgl)+(-28)))
Turns the system off at 28m AGL. The system turns on the flare before it turns off the descent for smoothness.
_
Flare Rotator: clamp01(Activate5)((clamp((((PitchAngle)+(-7))/10), -1, 1)clamp01(((AltitudeAgl)(-1))+(29.8)))+(clamp01(((AltitudeAgl)(-1))+(4))/2)
_
clamp01(Activate5)
Turns on the system when AG5 is enabled.
_
((clamp((((PitchAngle)+(-7))/10), -1, 1)
Pitches the aircraft to 7 degrees nose up in the flare.
_
clamp01(((AltitudeAgl)(-1))+(29.8)))
the system will only turn on when the airplane is below 29.8m AGL.
_
(clamp01(((AltitudeAgl)(-1))+(4))/2)
Turn off the system when the cockpit height is 4 meters AGL (which is my case the airplane is fully on the ground)
@klm747klm747 WOW! I don't know what magic you used to do that, but hot damn that's really cool.
@EpicPigster1 Thank you! It took about 5 hours to just get it working on that airplane. Now I have a stable platform and only changing one number can suit it for any aircraft!
@Omel Okay! All I have left to do it add details (windows, livery, N number, apu inlet, A/C pack inlet under the fuselage, Funky trees Ram Air Turbine, and a little bit of wing detail too). I might try and add every visible rivet on the wings if I feel like it.
@klm747klm747 WOAH! That autolamd system is seriously cool! It flared itself, DANG color me super impressed. Great work!
@EpicPigster1 By the way I've already finished an autolanding autopilot that can land your plane from any altitude. I finished it in the first 1.9 when rate(x) wasn't a thing yet, so I'm rewriting it to give me an exact descent rate on approach and an exact descent rate after the flare. This will give the landings consistency.
@Omel Thank you very much! I really wish SP had realistic weather because I would love to give it working wipers, but there's really no point.
So far, the features the aircraft has, link to activation groups, are
1- Flaps
2-Nothing
3-Spoilers
4-Lights
5-autoland
6-approach speed hold
7-autorotate for takeoff (I don't think the real 757 has this so I'll probably take it out)
8-engines
What two features should I put in place of AG2 and 7? I'm okay at funky trees so I'm really accepting any suggestions.
@klm747klm747 WOW! that plane looks amazing, doesn't have nearly as much upvotes as it deserves haha, it should have at least 75. This 757 looks great! Keep it up!
@Omel I just gave up and tried to make the middle block seem less obvious.
@EpicPigster1 Thank you for coming back to SP. You might remember me. I've come a long way in 2.6 years. My best project so far is here. It's 3800+ parts.
