Aero 9B nose turret from the Neptune at the National Naval Aviation Museum, Florida, 2007.Mostly the one foot longer Aero 9C turret was installed. Before the P-3 Orion arrived in the mid-1960s, the Neptune was the primary U.S. land-based anti-submarine patrol aircraft, intended to be operated as the hunter of a '"Hunter-Killer" group, with destroyers employed as killers.
The transponder gets its altitude information from an encoding altimeter mounted behind the instrument panel that communicates via the Gillham code. Gillham code is a zero-padded 12-bit binary code using a parallel nine- [ 1 ] to eleven-wire interface , [ 2 ] the Gillham interface , that is used to transmit uncorrected barometric altitude ...

Reversal errors are caused by a false static pressure reading. This false reading may be caused by abnormally large changes in an aircraft's pitch. A large change in pitch will cause a momentary showing of movement in the opposite direction. Reversal errors primarily affect altimeters and vertical speed indicators. [7]
The Bendix Central Air Data Computer contains complex electromechanical mechanisms. Electrical-mechanical air data computers were developed in the early 1950s to provide a central source of airspeed, altitude, and other signals to avionic systems that needed this data.
It is designed to read zero at sea level in the vicinity of the aerodrome, unlike QNH which will not read precisely zero at sea-level. [2] Related to the altimeter settings are: TA [3] - Transition Altitude - altitude at which the pilot changes the aircraft's altimeter setting (usually from QNH) to standard pressure (1013.25 hPa)
John Francis Rider (1900–1985) was an American radio engineer best known as publisher and author of over 125 books for radio and television servicing. He founded John F. Rider Publisher Inc. and was responsible for annual volumes of the Perpetual Troubleshooter's Manual from 1931 to 1954.
The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...
