# crrcsim(1)

a model-airplane flight simulation program

## NAME

crrcsim - a model-airplane flight simulation program

## SYNOPSIS

**crrcsim \[-fvhV\] \[-l *landscape-file*\] \[-c *cdepth*\]** **\[-x *xres*\] \[-y *yres*\]**\
 **\[-d *winddir*\] \[-w *windvel*\] \[-g *config-file*\] \[-s *on\|off*\]** **\[-u *on\|off*\]**\
 **\[-m *AILERON\|RUDDER*\]** **\[-b *nr:buttonfunc*\]** **\[-i *method*\]** *airplane-file*

## DESCRIPTION

**crrcsim** is a model-airplane flight simulation program for Linux with ports to other platforms. Using crrcsim you can learn how to fly model aircraft, test new aircraft designs, and improve your skills by practicing in the relative safety of your PC.

## OPTIONS

- \-b nr:buttonfunc

  Bind a joystick button to a function. *nr* is the number of the joystick button. For example, -b 2:INCTHROTTLE will increase the current throttle setting by 10% each time button #2 is pressed. See section BUTTON FUNCTIONS for a listing of all possible functions.

- \-c cdepth

  Color-depth in bits-per-pixel

- \-d winddir

  Wind direction in degrees.

- \-f

  Start in fullscreen mode.

- \-g config-file

  Specify a config file.

- \-h

  Display help and exit.

- \-i type

  Select input method.

- \-l landscape-file

  Load the landscape defined by  *landscape-file*

- \-m AILERON\|RUDDER

  Specify which function is controlled by horizontal mouse movement (if the input method is set to MOUSE).

- \-s on\|off

  Enable/disable sound (default: on).

- \-u on\|off

  Enable/disable graphical user interface (default: on).

- \-v

  Enable on-screen display of some values. This option may be specified up to three times.

- \-V

  Only print version information and exit.

- \-w windvel

  Wind velocity in ft/s.

- \-x xres

  Horizontal resolution in pixels.

- \-y yres

  Vertical resolution in pixels.

## BUTTON FUNCTIONS

- PAUSE

  Pause the simulation.

- RESUME

  Resume the simulation from pause mode.

- RESET

  Restart the simulation with the current configuration.

- ZOOMIN

  Increase the zoom factor of the current view.

- ZOOMOUT

  Decrease the zoom factor of the current view.

- INCTHROTTLE

  Increase the throttle by 10%.

- DECTHROTTLE

  Decrease the throttle by 10%.

## INPUT METHODS

- KEYBOARD

  The airplane is controlled by the keyboard.

- MOUSE

  Elevator and either aileron or rudder (depending on the **-m** option) are controlled by the mouse. Throttle can be adjusted by using the keyboard.

- JOYSTICK

  The airplane is controlled by the joystick. Control functions can be mapped to the joystick axes with the **-b** option.

- RCTRAN

  Reads the PPM signal from an r/c transmitter using the parallel port and the rctran kernel module.

- SERPIC

  For PPM interfaces connected to a serial port (aka 'FMS interface').

- SERIAL2

  A different serial port interface.

- PARALLEL

  Reads the PPM signal from an r/c transmitter using the parallel port.

- AUDIO

  Reads the PPM signal from an r/c transmitter using a sound card.

- MNAV

  Interface to the MNAV autopilot system.

- ZHENHUA

  For Walkera transmitters connected directly to the serial port.

## FILES

*~/.crrcsim/crrcsim.xml*

Default configuration file. Overridden by the **-g** option.
