When selected, the ND displays conventional HSI symbology, including a
selected course needle, a lateral deviation indicator, and a TO-FROM
indicator. VOR1, VOR2, and ADF navigation are displayed with a magenta
single line FMS1 (
), a cyan single line VOR1 needle (
), and a green
double line VOR2 needle (
), and ADF (
) tuned to an NDB. When the
signal is invalid, the associated pointer is not shown. When the HSI NAV
source fails, a red “X” is displayed in place of the HSI deviations.
