On RNAV approach, VGP is considered active when it is which color?

• A. Green
• B. Red
• C. Amber
• D. Off

Answer: (A)

The color of the vertical guidance indicator shows whether VNAV is actively guiding the descent. When the VGP is green, vertical guidance is active and the flight director/autopilot is following the published vertical profile down the approach. That’s the state you rely on for a stabilized descent with vertical guidance.

Red would mean vertical guidance is not available or there’s a fault, amber typically indicates it’s not actively guiding yet or is in a supervisory/armed state, and off means no vertical guidance is selected.
