HSI/ADI System AV20
The Avotek AV20 HSI/ADI Training System is designed to allow instruction on typical analog aircraft gyro systems. The system combines a magnetically slaved gyroscopic compass with a VOR/LOC and glide slope display. The combination provides the flight crew with a pictorial display of aircraft position and heading relative to the selected VOR or Localizer course.
The unit can be operated independently or interfaced with the Avionics Training System AV22
