Which piece of equipment indicates the direction of flight in IFR equipped aircraft?

The directional gyro is a crucial piece of equipment in IFR (Instrument Flight Rules) equipped aircraft, as it provides the pilot with a reliable indication of the aircraft's heading. It works by maintaining a constant reference to the Earth's magnetic field, allowing the pilot to navigate in instrument conditions where visual cues are limited. The directional gyro is essential for ensuring that pilots can maintain their desired course, especially during long flights or when flying in challenging weather conditions.

Unlike other instruments, such as the airspeed indicator, which primarily measures speed, or the attitude indicator, which shows whether the aircraft is level, climbing, or descending, the directional gyro specifically provides information on the aircraft's orientation relative to magnetic north. This function is vital for navigation and maintaining situational awareness in IFR operations. While the clock may serve other purposes, such as timing, it does not play a role in indicating flight direction.
