What provides the status of an aircraft, including attitude, airspeed, altitude, and heading?

The correct choice is telemetry because it encompasses the comprehensive communication and transmission of aircraft data, including attitude, airspeed, altitude, and heading, typically gathered from various sensors onboard the aircraft. Telemetry systems enable real-time monitoring and data analysis, which are critical for flight operations, especially in unmanned aerial vehicles (UAVs).

A flight data recorder captures flight parameters but is primarily used for recording data for later analysis rather than providing real-time status. An airspeed indicator specifically measures airspeed, while an altimeter exclusively gauges altitude. Both the airspeed indicator and altimeter are essential instruments within the cockpit but do not convey the full spectrum of data regarding the aircraft's overall status like telemetry does.
