SALS - Shuttle Approach & Landing Simulator

DEMONSTRATION PROGRAM USER NOTES

The SALS Demo is a much-simplified version of SALS, a high-fidelity
simulation of Space Shuttle approach & landing.  SALS Demo is intended to  
let you experience the general "look and feel" of flying a Space Shuttle
approach.  The demo provides:
  
  - Detailed visual scene of the Kennedy Space Center area
  - Complex, working instrument panel, re-creating the critical flight
    instruments used by Shuttle astronauts during landing
  - Working Guidance, Navigation, and Flight Control systems, modelling
    the GN&C functions provided by the Shuttle onboard computers
  - Both Autopilot and Man-in-the-loop capabilities.

If you enjoy the SALS demo, you'll like the full-up version even better!
It provides the following additional capabilities:
   
   1) A graphical user interface
   2) Night visual scenes
   3) Selectable/Creatable initial conditions (Orbiter location, winds, etc.)
   4) Exterior "chase plane" visual capability
   5) Post-flight "instant replay" capability
   6) SoundBlaster(R) support with realistic cockpit and air-to-ground
      voice traffic
   7) A 64-page User's Guide providing details on how to fly SALS; how to
      create a variety of simulation starting points; how to correctly fly
      both nominal and off-nominal shuttle trajectories; methods for cor-
      rectly interpreting and using the cockpit instruments; and other stuff.

END DO

For simplicity, a number of user-friendly set-up features of the full-up 
SALS program are missing from this demo.  For instance:
  
  1) The SALS demo expects to be located in a directory called \SALSDEMO\ 
     just under the root directory on your hard disk.  You must create 
     this directory yourself and copy the SALS files to it, if you have
     not done so already.

  2) After running SALS386.EXE or SALS387.EXE, your first action should be 
     to calibrate your joystick (if you have one).  To do this, run 
     JOYCAL.EXE.

  3) Two different versions of the SALS demo are available.  SALS_86.EXE 
     will run on any 386/486 system, but is somewhat slower than SALS_87.EXE.
     SALS_87.EXE will run ONLY on systems equipped with a math coprocessor
     (i.e. 387 or any 486DX system).  SALS_87.EXE will run at a higher frame
     rate than SALS_86.EXE.  If your system is not coprocessor equipped,
     do NOT run SALS_87.EXE.
  
  4) The demo user interface is minimal.  The full-up version features an
     easy-to-operate installation program and graphical user interface in
     order to access all the SALS capabilities.

The remainder of this file consists of a hyper-condensed form of the User's
Guide, just enough to get you through the basics of flying SALS.

STARTING SALS:
       
       NOTE:  These instructions assume you installed to the           
              C:\SALSDEMO directory

1.      Change to the Shuttle Landing Simulator directory:
        CD\SALSDEMO[ENTER]

2.      Start the simulator:
        SALS_86[ENTER] (or SALS_87[ENTER])


STOPPING SALS:
1.      Press [PF1] to return to DOS.


FUNCTION KEY CONTROLS:

F1:     Ends simulation and returns to SLCC.
F2:     Toggles Speedbrake control between Auto and Manual.
F3:     Arms & deploys landing gear.  The simulator automatically deploys 
        the gear at the correct point; however, this key allows earlier 
        deploy, if desired.  1st input arms the gear if not yet armed 
        automatically (occurs at 2000 ft); an input after the gear have 
        been armed deploys the gear
F4:     Toggles crew CRT display (the "green screen") between the 
        VERT SIT and HORIZ SIT display formats.
F5:     Apply brakes during rollout (*0.25 ft/sec2 per keystroke).
F6:     Release brakes during rollout (*0.25 ft/sec2 per keystroke).
F7:     Builds a Reset Point (a selectable trajectory initial condition) 
        based on current shuttle position and velocity.
F8:     Toggles Heads-Up Display (HUD) on and off.
F9:     Open speedbrake, when in Manual (5% per keystroke).(see F2)
F10:    Close speedbrake, when in Manual (5% per keystroke).(see F2)
F11:    Arms Drag Chute for Deploy.
F12:    After F11 Arm, first press deploys the Drag Chute; the second 
        press jettisons the Drag Chute.


FLYING THE SIMULATOR

The simulator has two flight control modes:

AUTO    All flying is handled by the autopilot in response to 
        guidance system commands.

CSS     (Control Stick Steering)  The flight is controlled in one or more 
        axes by the pilot.  CSS control may be applied to the pitch axis 
        (nose up/down) only, a combined roll/yaw axis (roll left/right) 
        only, or both simultaneously.  Any axis not under CSS control is 
        driven by the AUTO system.  CSS control is indicated by two 
        indicator lights at the top of the control panel, labeled "CSS P" 
        for pitch and "CSS R/Y" for roll/yaw.

SELECTING CSS:
   If joystick control: 
      *** NOTE - be sure to run JOYCAL.EXE once before using joystick ***
      Trigger 1 toggles between CSS and AUTO Pitch,
      Trigger 2 toggles between CSS and AUTO Roll/Yaw.

   If keyboard control or no joystick triggers: 
      Use the keyboard arrow keys (standard or numeric keypad):

      The first time [UP ARROW] or [DOWN ARROW] key   
          is pressed engages CSS Pitch;   
      The first time a [LEFT ARROW] or [RIGHT ARROW]  
          key is pressed engages CSS Roll/Yaw.    

RETURN TO AUTO:
   If joystick control:

       Trigger 1 toggles between CSS and AUTO Pitch
       Trigger 2 toggles between CSS and AUTO Roll/Yaw.

   If keyboard control, or no joystick triggers:   
       [SPACE BAR] returns both axes to AUTO.                 
        
PILOTING:
   If joystick control:

      Stick forward/backward commands pitch rates down/up, respectively; 
      Stick left/right commands roll rates left/right, respectively;
      Center stick commands zero rate in corresponding axis.

   If keyboard control: use the keyboard arrow keys.       
       NOTE:  Keys correspond to direction of joystick motion:                 *
       [UP/DOWN ARROWS] command nose-down/up pitch rate;       
       [LEFT/RIGHT ARROWS] command left/right roll rate;               
       Each input commands a 1.0 deg/sec rate increment                 
       Numeric pad key [5] commands zero rate in both axes.            
       [CTRL]+arrow key commands zero rate in selected axis
