Which instrument provides information on both pitch and roll commands?

The Attitude Director Indicator is specifically designed to provide pilots with essential information regarding both pitch and roll commands, making it a vital instrument for maintaining proper aircraft orientation in three-dimensional space. This instrument visually represents the aircraft's attitude relative to the horizon, indicating whether the aircraft is climbing, descending, or turning, as well as showing the degree of bank (roll) in the turns and nose-up or nose-down position (pitch).

Understanding the dynamics of flight, the ability to interpret pitch and roll accurately enables pilots to make informed decisions about flight maneuvers, especially under various flight conditions. The attitude indicator’s display assists pilots in maintaining the desired flight path and helps them recover from unusual attitudes effectively, which is crucial for safety and operational efficiency during flight.

Other instruments listed do not provide information about both pitch and roll simultaneously or focus on different aspects of flight. Thus, the Attitude Director Indicator stands out as the instrument that meets the requirement of delivering comprehensive pitch and roll information.
