Final answer:
The vertical deviation pointer is displayed as a glideslope indicator. In ILS/LOC mode, the glide slope and deviation pointer will be centered. In VOR or other modes, the course deviation pointer will indicate the horizontal deviation from the desired course.
Step-by-step explanation:
The vertical deviation pointer is displayed as a glideslope indicator.
When you are in ILS/LOC mode, your glide slope and deviation pointer will be centered.
When in VOR or other modes, the course deviation pointer will indicate the horizontal deviation from the desired course.
