6.
TOI FROM INDICATOR FLAG - Indicates direction of VOR
station relative to selected course.
7.
DUAL GLIDESLOPE POINTERS - Indicate on glideslope scale
(8) aircraft displacement from glideslope beam center. Glideslope
. pointers in view indicate a usable glideslope signal is being received.
8.
GLIDESLOPE SCALES - Indicate displacement from glideslope
beam center. A glideslope deviation bar displacement of 2 dots,
represents full scale (0.7°) deviation above or below glideslope
beam centerline.
