Deviation Bar and Scale

The VOR deviation bar shows in magenta. The DEUs use VOR bearing from the VOR/MB receivers and course inputs from the DFCS mode control panel to calculate VOR deviation. The scale is the standard four dot scale. One dot equals five degrees of deviation.

The DEUs remove the deviation bar for NCD deviation inputs from the VOR/MB receivers.

Selected Course Pointer

The course select control on the DFCS mode control panel sets the position of the selected course pointer.

TO/FROM Pointer and Indicator

The TO/FROM pointer is a small white triangle that shows as part of the selected course pointer. The TO/FROM pointer shows on the centered VOR display only.

The TO/FROM indicator shows at the bottom right corner of both the centered and expanded VOR displays. The DEUs use VOR bearing from the VOR/MB receivers and course inputs from the DFCS MCP to calculate TO/FROM pointer and indicator displays.

The TO indication shows when you enter a course on the DFCS MCP that takes you to the VOR station. The FROM indication shows when you enter a course that takes you away from the VOR station.

The DEUs remove the TO/FROM pointer and indicators for NCD and invalid displays.

NAV Data Source

The DEUs show the source of the data for the ND display in the upper right corner. The normal source for the captain NAV display is the VOR/MB receiver 1 and the normal source for the first officer is the VOR/MB receiver 2.

VOR Frequency

The VOR frequency shows in the upper right next to the NAV data source. The frequency from the NAV control panel goes through the VOR/MB receivers, then to the DEUs for display. The frequency shows in green. IF the VOR receiver gets a valid station identifier from the VOR station, the station identifier replaces the VOR frequency.

The DEUs change the VOR frequency to dashes for NCD inputs from the VOR/MB receivers.

 

 

VOR SYSTEM - EFIS INVALID DISPLAYS

Invalid Display

The DEUs remove these displays for invalid VOR/MB receiver inputs:

· Deviation bar and scale

· TO/FROM pointer and indicator

· VOR frequency

· NAV data source

· Bearing pointers.

 

The DEUs show the amber VOR flags on both the centered and expanded VOR displays for VOR/MB receiver failures.
