The instrument panel also provides navigation information. The MFD symbolizes<br />
your position, the waypoint , and the desired flight path to the next selected<br />
waypoint. The ADI yellow predictor bars (“needles”) mark the desired bank and<br />
pitch angles while the HSI shows the required heading and distance to the next<br />
waypoint. In general, if the HUD becomes unserviceable, you can still navigate<br />
using the instrument panel.<br />
The VFHI (ENR) submode provides no combat information. Generally speaking,<br />
select this mode, set your course, and then select a more appropriate combat<br />
mode. Occasionally return to VFHI (ENR) mode to verify your flight path. Press<br />
the ~ key to cycle through waypoints.<br />
Reading the VFHI (ENR) Submode instrumentation<br />
In the figure above, the aircraft on approach to waypoint 2 is misaligned by<br />
about <strong>35</strong>° to the left. This is reflected on the HSI (see the instruments at the<br />
bottom of the figure): the current heading is 20 and the ADF arrow (the narrow<br />
needle) reads 55°. The distance to waypoint 2 is 30 km (upper-left corner of the<br />
HSI). The desired radial, the desired flight path from waypoint 1 to waypoint 2,<br />
is shown by the flight path marker (the wide needle). In other words, the ADF<br />
needle points directly to the next waypoint while the flight path marker points<br />
to the pre-programmed flight path to that same waypoint.<br />
The ADI also shows the misalignment between the aircraft’s heading and the next<br />
waypoint. The required bank needle points to the right, indicating the aircraft
