VERTICAL DEVIATION SCALE AND POINTER
When instrument landing system (ILS) glide slope,
GS, is selected or GPS glide path, GP, descent is
active when GPS in selected. The vertical
deviation display consists of a white rectangular
center point with two white hollow dots above and
below and a pointer indicating current glide slope/
glide path deviation.
When vertical deviation is outside the limits of the
scale, the deviation pointer parks at the
appropriate end of the scale with half the pointer
out of view.
Vertical Deviation Invalid
If vertical deviation data is invalid, the pointer is
removed and a red X is placed over the deviation
scale. If vertical information is provided in ARINC
429 format, the vertical deviation scale is removed
when invalid. Refer to installer for your aircraft’s
specific configuration.
