FOR SIMULATION PURPOSES ONLY
Full scale deflection represents approximately ½ degree deviation from the
ideal glide path.
Compass Warning Flag
A red flag labelled HDG is visible in the upper right quadrant of the display
whenever the power supplied is inadequate or the gyro is not up to speed.
If this flag is in view then the heading information is unreliable but the
VOR/localizer and glide path deviation bars, the To/From indicator and the
NAV flag will continue to give correct information.
NAV Warning Flag
This red flag appears in the upper left quadrant whenever an unusable
VOR/localizer signal is being received or the NAV receiver unit is not turned
on.
NAV/GPS Selector
The NAV/GPS button directs either NAV 1 or GPS information to the HSI
selected course deviation bar, however a safety system ensures that GPS
information is not connected when an ILS frequency is selected on NAV 1.
The NAV/GPS button light will default to NAV when an ILS frequency is put on
NAV 1 (if GPS was selected).
