What are the basic modes of the Flight Director?

The Flight Director is a critical component of an aircraft's avionics, providing guidance to the pilots for controlling the aircraft along a desired flight path. The basic modes of the Flight Director primarily involve controlling the aircraft's attitude to maintain or achieve specific flight parameters.

The correct choice refers to Roll and Path, which are fundamental aspects of how a Flight Director operates. The Roll mode guides the pilot in adjusting the aircraft's bank angle to follow a designated lateral flight path, while the Path mode aids in managing vertical navigation by directing the aircraft to achieve the intended altitude along the flight path.

Understanding these modes is essential for pilots, as they provide the necessary cues required for safe and efficient flying. The other options, while they encompass important aspects of flight management, do not precisely describe the core functional modes of the Flight Director. Roll and Path specifically highlight how pilots interact with these instruments to maintain control and navigation.
