Which of the following is a primary function of a flight director?

The primary function of a flight director is to enhance the pilot's situational awareness visually. It does this by providing commands that guide the pilot on how to maneuver the aircraft effectively, which can be displayed on the aircraft's attitude indicator or on other screens. This visual representation assists pilots in understanding the necessary flight path adjustments while allowing them to maintain control over the aircraft, especially during complex maneuvers or approaches.

This understanding is critical for safe operations, as the flight director helps pilots integrate various aspects of flight management, including maintaining altitude, heading, and navigation, without taking direct control from the pilot. While the flight director aids in navigation by providing visual cues, it does not perform navigation tasks automatically or provide audio commands directly; it requires pilot interpretation and action. Additionally, tracking fuel consumption is not within the typical scope of a flight director's functions, which are more focused on guiding the pilot during flight maneuvers.
