Which option correctly defines NAV mode during approach?

• A. NAV = join the approach
• B. NAV = Cleared for the approach
• C. NAV = after touchdown
• D. NAV = during go-around

Answer: (A)

NAV mode means the aircraft is being guided by a navigation source (GPS, VOR, etc.) to follow a specific route. On approach, using NAV mode focuses the flight path to join the published approach by steering toward the initial approach fix and then along the approach course. It sets you up to intercept the approach track and begin the transition into the instrument approach sequence. This is why the interpretation that NAV means joining the approach is the best fit. Being cleared for the approach is ATC authorization, not a flight guidance mode. After touchdown and during a go-around involve different phases and modes, not the NAV mode used to join the approach.
