Collins Indicator IND-351A aircraft part – photo 1

Description

The Collins IND-351A is a dual-pointer GPS/VOR/LOC/Glideslope indicator from the respected Collins Microline series, widely used in general aviation. It features rectilinear meter movements for easier ILS approaches and a mechanical metal case upgrade over the older, crack-prone IND-351.

Key Specifications & Features:

  • Design: Mechanically improved with a metal chassis to prevent the cracking plastic issues seen in the standard IND-351.
  • Meter Movements: Uses rectilinear movements rather than pendulum, keeping needles perpendicular and making tracking approaches (like ILS) highly intuitive.
  • Converters: Does not contain an internal VOR/LOC converter or glideslope receiver. It relies on the external NAV radio (e.g., Collins VIR-351) or a remote glideslope receiver (e.g., Collins GLS-350) for this data.
  • Compatibility: Works with standard NAV equipment including the Garmin GNS 430/530, GTN 650/750, and KX-165. Paired with an Annunciator Control Unit (ACU), it can meet FAA requirements for IFR GPS installations.
  • Part Number: 622-4478-001.
