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.
February 23, 2008 – A B-2 bomber took off from Andersen Air Force Base in Guam and subsequently crashed after stalling. It was caused by moisture on the air-speed sensors. [11] 1 June 2009 – The French air safety authority BEA said that pitot tube icing was a contributing factor in the crash of Air France Flight 447. [12]
An air data computer (ADC) or central air data computer (CADC) computes altitude, vertical speed, air speed, and Mach number from pressure and temperature inputs. [1] It is an essential avionics component found in modern aircraft.
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 ...
An ISIS is designed to combine the functions of separate equivalent mechanical instruments that had previously been included as backup in such cockpits, including altimeter, airspeed indicator, and attitude indicator. Various aspects of ISIS are defined by its function of being a backup to conventional instrumentation.
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)

[1] [2] It is a primary instrument for flight in instrument meteorological conditions. [3] [4] Attitude is always presented to users in the unit degrees (°). However, inner workings such as sensors, data and calculations may use a mix of degrees and radians, as scientists and engineers may prefer to work with radians.
