Which of the following is NOT a warning provided by the ground proximity warning system (GPWS)?

The ground proximity warning system (GPWS) is designed to prevent controlled flight into terrain and provide warnings to pilots about potential hazards. It does this by monitoring the aircraft's altitude, configuration, and flight path.

The warning issued for an impending stall is critical because it alerts pilots when the aircraft's speed is dropping to a level that could lead to a stall, which can occur if the aircraft is not at an appropriate angle of attack or speed. Altitude loss after take-off or during a go-around is also crucial, providing warnings about potentially dangerous situations where the aircraft is losing altitude unexpectedly after it has become airborne, which can lead to terrain collision if not corrected.

Incorrect landing configuration is another important warning that informs the pilot when the aircraft is not in a proper configuration for landing (e.g., flaps or landing gear not correctly set). This warning is essential to ensure a safe landing approach.

In contrast, excessive climb rate is not a recognized warning from the GPWS because the system primarily focuses on alerts that are critical for preventing terrain conflicts rather than monitoring performance in climb scenarios. A climb rate that is deemed excessive does not directly correlate to the potential for ground proximity issues or terrain collision, thus it is not part of the GPWS alert features.
