Flying the Flight Path Vector (FPV) at 3 degrees below the horizon line will result in what?

When the Flight Path Vector (FPV) is flown at 3 degrees below the horizon line, it indicates that the aircraft is descending along a glidepath that is effectively set at that angle. The FPV represents the actual trajectory of the aircraft, and when it is positioned below the horizon, it signifies the intention or action of descending.

Flying at a 3-degree glidepath is a common practice in flight operations, particularly during approaches to landing. A descent angle of 3 degrees is often used in standard procedures, such as ILS approaches, providing a manageable rate of descent that allows for smooth transitions during landing. This is why the correct understanding is that maintaining the FPV at this angle will establish a consistent glidepath, leading the aircraft down towards the runway at a rate that is safe and efficient for landing.

Other choices might describe different scenarios, such as level flight or a specific descent rate, but they do not accurately reflect what occurs when the FPV is set specifically at a negative angle below the horizon for a glidepath. In summary, a 3-degree descent will ensure the aircraft is effectively on a glide slope towards the intended destination when monitored correctly with the FPV.
