Height Deviation Indicator

The Height Deviation Indicator is a type of radio navigation equipment that is used in airborne applications. It falls under the supply class of Radio Navigation Equipment and is categorized within the supply group of Communication, Detection, and Coherent Radiation Equipment.

The Height Deviation Indicator is designed to provide pilots with accurate information about the aircraft's vertical position relative to a desired flight path or altitude. It typically displays the deviation of the aircraft's altitude from the desired altitude, allowing the pilot to make necessary adjustments to maintain the desired flight level.

This equipment is crucial for safe and efficient navigation, especially during instrument flight conditions or when flying in congested airspace. It helps pilots maintain proper altitude clearance, avoid obstacles, and adhere to air traffic control instructions.

The Height Deviation Indicator is typically integrated into the aircraft's avionics system and may include features such as digital displays, warning alerts, and compatibility with other navigation instruments.

Overall, the Height Deviation Indicator plays a vital role in ensuring accurate altitude control and navigation for airborne operations.
