The Bendix Horizontal Situation Indicator (HSI), model number 40000172-8572, is a precision avionics instrument designed to provide pilots with essential flight information in a clear and concise manner. This HSI is a slaved unit, meaning it derives its heading information from a primary flight display or autopilot system, ensuring accurate and synchronized heading and course deviation indications.
The HSI consists of a large, easy-to-read circular dial with a red pointer, which shows the aircraft's magnetic heading. An outer ring, marked with degrees 0 through 360, indicates true heading. The horizontal situation indicator also displays the aircraft's course deviation from a selected navigation source, such as a VOR or NDB, on a horizontal scale. The course deviation indicator is marked with a yellow pointer and is calibrated in degrees left or right of the selected course.
The HSI features a backlit display, ensuring easy readability in low-light conditions. It also has a selectable baro setting, allowing pilots to set the barometric pressure according to their flight altitude and location. This information is crucial for calculating accurate airspeed and altitude readings.
The HSI is designed for installation in both glass cockpit and traditional analog instrument panels. It is compatible with various avionics systems and can be interfaced with a wide range of autopilots and flight directors. The dimensions of the unit are approximately 3.1 inches in height, 4.3 inches in width, and 6.3 inches in depth, making it a compact yet powerful addition to any cockpit instrument panel.
The Bendix 40000172-8572 HSI is built to meet or exceed FAA TSO-C129b and TSO-C88b standards, ensuring the highest level of reliability and safety. It is also backed by Bendix/King's industry-leading warranty and support, giving pilots peace of mind during their flights.
In summary, the Bendix Horizontal Situation Indicator, model 40000172-8572, is a versatile and essential avionics instrument that provides pilots with accurate and synchronized heading and course deviation information. Its large, easy-to-read display, compatibility with various systems, and robust construction make it an indispensable tool for any aviator.
