Use Case
The Bendix INA-12B-2 indicator is a cockpit instrument used in various commercial aircraft, including early Boeing 737 models. Its primary function is to display critical navigation information related to wind effects on the aircraft's flight path:
- Drift Angle: The main dial and the white airplane symbol indicate the real-time drift angle (in degrees, left 'L' or right 'R') caused by crosswinds, showing the difference between the aircraft's heading and its actual ground track.
- Ground Speed: The white digital counter at the bottom of the dial displays the precise ground speed of the aircraft in knots, which is its actual speed relative to the Earth's surface.
This information is typically derived from an Inertial Navigation System (INS) or an Air Data Computer (ADC) and allows the flight crew to make necessary adjustments to maintain the intended course.
