    General Question Plane changes give me a bad attitude

    I did it Better Update of Rotational Properties (BURP) tries to fix the rolling. It subtracts the prograde rotation from the current rotation, finds the shortest path (rather than just using whatever the difference is even if it takes the long way around), finds the longest of the x, y, z...

    News Wild orbit math finds a place to park a satellite

    I got stuck at L1 just last week. (But what orbinaut didn't already know this?) ;-) https://www.bloomberg.com/news/features/2018-07-25/one-woman-s-math-could-help-nasa-put-people-on-mars

    General Question Transx: Earth to...Earth?

    It looks like you're trying to automate launching into orbit. There are better ways. You can watch this: There is an autopilot MFD that you can use for takeoff, align planes, sync orbit and dock. I think it's here: Autopilot 1.72 with AIRAC and worldwide Airports Google autopilot MFD. Or...

    Problem White Screen on Startup?

    :idea: I had the same problem It came down to using an unsupported screen resolution size. In the Video page there is the choice of Full Screen and Window. The Full Screen has a dropdown of supported resolutions and the Window version doesn't. the Window setup should take anything with a...

    Orbitr mobile phone app

    I know the feeling No, I think the OP was saying s/he's like to play Orbiter from his/her mobile device. I would. The best you can do (how could you fit everything on one little screen) is to watch Youtube videos. KFC (?) to ISS is good. Or, I just found Atlantis to orbit. It would be cool...

    General Question Plane changes give me a bad attitude

    In the Orbiter.pdf (v. 2016) on page 62 there is that lovely diagram showing the attitude of the ship at prograde, retrograde, orbit normal and orbit anti-normal. It seems that rolling from one to the other would be more fuel efficient if the ship rolled only on one axis.(*) The roll code...

    Problem Link to online Orbiter.pdf is to V 2010

    FYI, (I just found Orbiter 2016 - I'm a little behind) and used my link to the online Orbiter.pdf and found that it goes to Orbiter.pdf (2010). (That's why I didn't know that Orbiter had been updated.) I assume that the file has been updated. Yes, I found the new file in the Doc directory...

    General Question How do you read the Velocity/Direction indicators?

    I was close to ISS and then accidentally hit the main thruster. So now, I’ve been chasing ISS all over the place and keep over correcting. I’m trying to find a point of reference. I faced Prograde, so that I have some sense of direction, and can tell if ISS is at a different altitude, above...

    General Question Can't fly with joystick or keyboard

    Success! SUCCESS! I made it into orbit on fly-by-wire mode (without auto-pilot). I used the Level Horizon AP to control the rolling. Ok, I guess I did use some AP. I put the hover engines on full, yawed right to 42 degrees, put main engines on full, after a few seconds, turned off the hover...

    General Question Can't fly with joystick or keyboard

    Well that explains his non-committal attitude when I asked him about trim. He didn't elaborate. You can see why he's my least favorite brother. He only flew for himself and he doesn't even do that anymore. I was thinking of the flaps when a plane come in for a landing. They move a lever...

    General Question Can't fly with joystick or keyboard

    First of all, thanks for your replies. Hielor, I checked with my brother who is a pilot to confirm what I thought – the trim tabs are really to balance the plane (front to back/left to right) do to the weight differentiation of the load (passengers/cargo) so that the plane flies straight and...

    General Question Can't fly with joystick or keyboard

    The first time I used a flight simulator, I pitched up to the angle I wanted, let go of the joystick to do some keyboard operation (like raise the landing gear), and nosedived into the ground. It seems like you don't have to map the joystick input directly to the ships angle. The same with...

    General Question Universal Autopilot UAP scripts

    Is anyone posting UAP scripts? Are people typing them in by hand to a .scn file? I'd love to get a script for the DG-IV that takes me to ISS, the moon, doing a slingshot to Saturn or somewhere. Is there any other documentation other then the uap_doc.pdf (and the UAP folder with the .scn...

    General Question DG IV autopilot Align Plane and/or Sync Orbts

    Is there an Align Plane and/or Sync Orbits autopilot operation for the DG-IV? I want to set up/automate a round-trip run to some low orbit location. Take-off, dock, drop payload, un-dock, de-orbit, land. I'm looking for a Repeat/Re-execute command, too. What I want to do is setup up a...

    General Question Translation mode RCS

    Sorry, I was wrong. I can't delete this Sorry, i was away... The editor says this thread is over a month old but,... Can't you go from translation to rotation by pressing CTRL key? RCSPitchUp = NUMPAD2 RCSPitchDown = NUMPAD8 RCSYawLeft = NUMPAD6 RCSYawRight = NUMPAD4 RCSBankLeft = NUMPAD3...

    General Question Where is the SH-02 users manual?

    Thanks for the reply but... I can't find that doc still. Can you please provide a link to it? I looked here (http://orbit.medphys.ucl.ac.uk/docs.html) but, still can't find it.

    General Question Where is the SH-02 users manual?

    Where is the SH-02/Shuttle-A Technical Manual? I'm looking for the keys to operate the Aux Pod (left side-more/less, right side-more/less and both-more/less, rotate forward, rotate backward). Also, does anyone else notice a lack of retro-grade indicators in surface mode? I was going to do a 180...

    Flight Question Autopilot won't let me head East in DG, Launch MFD?

    OK. If anyone else finds this later... there is an autopilot running that points you Westish, not East. Click Pro Grade and it will turn you in the right direction. :-) I guess the game depends heavily on autopilot. I'm writing a flight-sim and do everything manually. Now, I can get to...
