Primary air data information is presented through which three electronic instrument displays?

The primary air data information in the T-6A is accurately represented by the choices that include the ASI (Airspeed Indicator), Altimeter, and VSI (Vertical Speed Indicator).

The ASI measures the current airspeed of the aircraft, which is critical for understanding performance during flight maneuvers. The Altimeter provides essential altitude information, indicating how high the aircraft is flying in relation to sea level. The VSI complements these instruments by showing the rate of climb or descent, giving pilots insight into vertical velocity changes.

This combination of instruments is fundamental for pilots to monitor and maintain safe flight profiles, especially during transitions such as takeoff, landing, or changes in flight configuration. Other options, while they may include important instrumentation, do not consist of the main trio that delivers primary air data information effectively for operational decision-making in the T-6A.
