What does DGU mean in UNCLASSIFIED

A Directional Gyro Unit (DGU) is an instrument used by pilots to assist with navigation of their aircraft. It provides the user with information such as heading, groundspeed, true airspeed and altitude.

The DGU works by monitoring changes in aircraft pitch, roll and yaw via sensors called gimbals. This data is then sent to the directional gyro unit's internal computer which processes it into usable information for the pilot.

The primary benefit of using a DGU is increased safety when flying since it allows pilots to accurately maintain their course while reducing workload. Additionally, it eliminates any potential errors that could be caused by manual calculations or incorrect readings from analog instruments. Lastly, DFUs help reduce fatigue since they allow pilots to make fewer corrections throughout a flight.

All instruments should be checked regularly for accuracy before each flight - however for DGUs, it is recommended that they are checked at least once every 30 days to ensure you have accurate data available during your flight.

An Integrated Flight Unit System (IFUS) is an integrated avionics package which includes multiple components such as autopilots, directional gyros and FMS systems which allow pilots to monitor their aircraft performance in real time during flights.
