Chalk River Graphics Simulation
CrgSim is a networked set of 777 style glass instruments that interface to Flight Simulator X. The instrument set consists of a pilot's primary flight display (PFD) and navigation (NAV) display, a First Officer's PFD and NAV Display, an engine-indicating and crew-alerting system (EICAS), a moving chart display, and an annunciator panel. The instruments may be run on the flight simulator computer or may be run across multiple computers on the local network to improve performance. When running on other (non-FSX) computers there is little impact on the flight simulator frame rate.

The instruments require DirectX 10 and should run on Vista, Win 7, Win 8, Win 8.1, and Win 10. Click on any image in the top row for more information. CrgSim is free to download and free to use.

The Nav display has seven modes of operation. The Nav image above shows the expanded map mode. The other 6 modes are shown below.

The "centered" nav displays represent the area around the aircraft at the selected range. The flight simulator aircraft is at the center of the 360 degree display. The "expanded" displays show a smaller area ahead of the aircraft, about 120 degrees. The CrgSim nav plan mode is always centered on a waypoint in the flight plan. The pilot can use the CDU and the nav plan mode to review the flight plan. If a flight plan has not been loaded the plan mode display will display "NO FLIGHT PLAN". While underway this display will show an aircraft icon as it travels to the next waypoint.

Centered Map Expanded VOR Centered VOR
The Nav VOR displays are useful when one of the Nav Radios is tuned to a NAV VOR ground station and a radial of interest has been entered on the aircraft Mode Control Panel (MCP). The Nav VOR display shows the relationship of the aircraft to the selected radial. The magenta bar in the center of the display shows the radial error (desired radial versus actual radial). The name of the tuned VOR is displayed in the upper right of the display and includes the distance to the VOR ground station.

The usual ground speed (GS) and true air speed (TAS) are displayed in the upper left of the VOR display. The name of the VOR that the left radio is tuned to (if any) is displayed in the lower left of the screen and the name of the VOR that the right radio is tuned to (if any) is displayed in the lower right of the screen.

Expanded Approach Centered Approach Plan Mode
The Nav Approach displays are used when landing at an airfield that has an Instrument Landing System (ILS). The ground station transmits both a signal for the glide path and for the horizontal path. The objective is to line up the magenta bar inside the display with the pointer to the ground station and to have the magenta diamond in the center of the scale (the glide path) that is to the right of the display. When both these indicators are centered the aircraft is in the proper location at that point in the landing.

The name of the ground station and the distance to the ground station is shown in the upper right of the display. If there is no ILS tuned on either Nav radio this display is inactive. The usual ground speed (GS) and true air speed (TAS) are displayed in the upper left of the VOR display.

All of the above images were taken from Crgsim instruments while connected to Flight Simulator X via FSUIPC. CrgSim should work with FSX Steam, FSX, and Prepar3d.
