Searchlight Azimuth-Elevation Indicator ID-277/AVQ-2, S2 Tracker, P2V Neptune US Coast Guard for taking bearings on objectsThis is a Searchlight Azimuth Elevation Indicator type ID 277 AVQ 2 as used in the Cold War era antisubmarine aircraft Lockheed P2V Neptune and Grumman S 2 Tracker, and Martin P5M Marlin Floatplane of the US Navy. The crewman or co pilot operated a handgrip to adjust the aim of the externally mounted searchlight, and the azimuth and elevation of the searchlight's beam relative to the position of the aircraft would appear on the indicator.
