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. DO Legal Stuff: *************************************************************************** SALS Demo is copyrighted, and is distributed as FREEWARE - you may copy and distribute it freely, provided no charge is made for the copy and that all the original files are included in the distribution; individual files may NOT be distributed. All rights are reserved by Binary Star Ltd. *************************************************************************** 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. ORDERING INFO The full-up version of SALS costs only $19.99, plus $5.01 for shipping and handling. To order the full-up version of SALS (which includes 2 3-1/2 inch diskettes and a 64-page illustrated manual), send your check or money order for $25 per copy (U.S. funds only) to: SALS Order Dept. Binary Star Ltd. P.O. Box 580568 Houston, TX 77058 Please allow 3-4 weeks for delivery. 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 TECHNICAL SUPPORT: 713-992-0945 - Please leave a description of your problem, your name, and a phone number. We will contact you within 24 hours.
