SAS: Hold Horizon

I support this.

I use MechJeb's Smart A.S.S. mode or Atmosphere Autopilot to hold a horizon lock. It'sa verra naaaice.

PART TWO!!!

This needs to exist.

Instead of just this one special case, I would support a generic 'Hold Current Navball Pitch and Roll Angles' setting.

This would provide what you request for the one special case of the horizon (zero pitch angle), plus any other pitch up or down angles one would wish for a controlled ascent/descent/reentry situation.

 

Do keep in mind that (especially for aircraft), pitch and roll does not have to equal flight path angle (the angle between your horizontal and vertical speed, or the surface prograde vector)

That is only the case where zero pitch will cause your aircraft to remain straight and level. If you want to make it more generic, a 'flight path angle hold' feature on SAS would be great. That means that pitch adjusts according to airspeed (pitching down when the craft speeds up, and pitching up when the craft slows down) to maintain the correct vertical speed.

I am very much in favor of a feature that can maintain FPA since it is very useful for any mode of surface flight.

I support this as well as auto-grav turn and hold vert as well. Auto land would be a Kerbal saver as well as.

Yeah I really didn't think that through :P

Maybe you are on to something...what if it locks to the navball, but does not get affected by the yaw action as you pass over the poles?
As in, it actually locks to a vector relative to the stars, but this vector gets continually updated by the "pitch curve" of the planet(so that airplanes do not end up pointing upwards)

The navball heading will definitely rotate as you change latitude, but we aren't concerned with that. Come to think about it, it sounds like using the surface velocity vector, rotating the vector reference to the "up" vector(away from gravity), and then replacing the pitch scalar with the locked value

Hold vertical = :radial: ...... :wink: 

Also...

@KerBlitz Kerman Change navball to "Surface mode", set SAS to hold radial-out...it wont actually aim at radial, but will aim at "Up"/"vertical". This is really useful for powered landing as well:
-Having almost zero vertical speed, makes the retrograde marker jump around the horizon, and a ship following that marker becomes a disaster.
-Switching to surface mode, and to hold radial-out will keep the ship upright. You can then just slightly tilt away from the direction of your horizontal speed

Thx @Blaarkies, and @JadeOfMaar, that will help for my VTOL adventures!

This also means that you can make a craft hold straight and level by putting a probe core (or docking port) on its roof and tracking "SAS Radial Out". The craft will then keep flying wings level, nose forward.

Something that has a little more precision or repeatability would actually be nice. I use MechJeb's Smart ASS because I can just enter attitude values numerically and change attitude one axis at a time, so I can keep control of my pitch vector while the heading stays locked, so the craft will get in orbit on the proper inclination. I hardly use any other feature from MechJeb, but the Smart ASS is great because you can follow the same launch profile for every mission, instead of having to guesstimate your attitude from the navball and correct with WASD.

I'd like to see it be a toggle on the navball. When it's set to atmospheric flight, it'll have horizontal prograde/retrograde markers, up/down markers, and horizontal sideways markers. These would replace the orbital markers that you see on the orbital navball. When you use the atmospheric flight navball, your Kerbal or probe core pilots would follow the new markers.
