1.2.3.13 VVI
The VVI (Vertical Velocity Indicator) located on the instrument panel displays vertical
velocity in thousandths of feet per minute.
The instrument features a vertically moving tape indicating an operating range from -
6000 to +6000 feet/min.
The instrument is flagged OFF when there is no power available.
1.2.3.14 INSTRUMENT MODE panel
This panel has been replaced by a blank panel in later blocks where the HSI has
been replaced with the EHSI. On the EHSI modes are changed with the M button.
The bottom knob is not implemented in BMS. In reality it is used to correct INS
heading deviation, which never happens currently in our sim. The top knob is a four-
position knob setting the instrument mode: ILS/TCN
– TCN – NAV – NAV/ILS.
•
ILS/TCN -
one of the two modes used to display the ILS needles. It activates
the ILS symbology in the HUD, the ADI and the HSI. The course deviation indicator
on the HSI gives the localiser deviation. The TO/FROM indicator is not displayed and
the bearing pointer points at the active TACAN station. The range value in the DME
window of the HSI is from the active TACAN station and not the ILS.
•
TCN -
the HSI displays course deviation and distance from the active TACAN station. ILS
symbology is not displayed. All HSI indicators point to the TACAN station. The TO/FROM
indicator is displayed.
•
NAV -
the HSI displays course deviation and distance from the steerpoint of interest (active
UFC Steerpoint) and not the TACAN. The TO/FROM indicator is displayed.
•
ILS/NAV -
ILS symbology is displayed as in the other ILS mode in the HUD, ADI and HSI.
The course deviation indicator on the HSI gives the localiser deviation, the TO/FROM
indicator is not displayed, the range in the DME window is given to the steerpoint of interest
(and not the ILS) and the bearing pointer on the HSI points to the steerpoint of interest as
well.

1.2.3.15 EHSI
Block 50 and Block 52(+) have been updated with the electronic version of the
Horizontal Situation Indicator. The EHSI is the primary flight instrument for
navigation. It features a top down view with your aircraft in the centre and a
compass rose all around it. Its use is fully explained in the BMS Comms and
Nav book that explains basic and advanced radio-navigation.
The instrument features two knobs and one M button on the bottom, the left
knob labelled HDG for Heading is used to set a heading caret on the compass
rose to a heading of your choice (as a visual cue).
The right knob labelled CRS for Course is used to enter a course value
manually which will be reflected on the course deviation indicator. That value is displayed on the top
