Gyroscopic Heading Indicator Subassembly

The Gyroscopic Heading Indicator Subassembly is a component of the Flight Instruments supply class, which falls under the Instruments And Laboratory Equipment supply group.

The Gyroscopic Heading Indicator is an instrument used in aircraft to display the aircraft's heading or direction of travel. It is based on the principle of gyroscopic precession, where a spinning gyroscope maintains its orientation in space. The Gyroscopic Heading Indicator Subassembly consists of various components, including the gyro rotor, gimbal system, and a display mechanism.

The gyro rotor is the spinning element of the instrument, which is driven by a motor or air flow. It maintains its orientation in space and provides a stable reference for the heading indication. The gimbal system allows the gyro rotor to move freely in response to changes in aircraft attitude, ensuring accurate heading indication.

The display mechanism is responsible for converting the gyroscopic motion into a visual indication of the aircraft's heading. This can be in the form of a dial or digital display, which is calibrated in degrees or cardinal directions.

Overall, the Gyroscopic Heading Indicator Subassembly is a critical component of the Flight Instruments supply class, providing pilots with essential information about the aircraft's heading during flight.
