The flight path vector and flight path director are displayed when which mode is selected?

• A. NAV mode
• B. TRK-FPA mode
• C. HDG mode
• D. ALT mode

Answer: (B)

Track-Flight Path Angle mode uses guidance based on an actual path through space, not just a heading or altitude target. When this mode is selected, the cockpit shows the Flight Path Vector, which indicates where the aircraft is actually flying relative to the ground, and the Flight Path Director, which provides visual cues to steer toward the desired track and flight path angle. This combination helps the pilot visually manage both horizontal track and vertical path to achieve the specified trajectory. In contrast, other modes focus on different targets: NAV mode guides along a navigation course without relying on an explicit flight-path path, HDG mode centers on maintaining a heading, and ALT mode focuses on capturing or holding a selected altitude. None of these modes inherently emphasize the flight-path cues in the same integrated way as TRK-FPA, so the FPV and FPD are not the primary display elements there.
