MIL-W-46374 is a specification first published on October 30, 1964, [1] for US military watches. [2] The 46374 was specified as an accurate, disposable watch. In its span, it encompassed metal and plastic cased watches with both mechanical and quartz movements. [2] The 46374 replaced the MIL-W-3818, reducing cost and inheriting the dial from ...
This is a list of United States Army fire control, and sighting material by supply catalog designation, or Standard Nomenclature List (SNL) group "F".The United States Army Ordnance Corps Supply Catalog used an alpha-numeric nomenclature system from about the mid-1920s to about 1958.
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 ...
Pressure altimeters must be calibrated prior to flight to register the pressure as an altitude above sea level. The instrument case of the altimeter is airtight and has a vent to the static port. Inside the instrument, there is a sealed aneroid barometer. As pressure in the case decreases, the internal barometer expands, which is mechanically ...
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 ...
Revue Thommen developed and supplied altimeters, airspeed indicators, vertical speed indicators, clocks, and the landing gear for the Swiss multifunction biplane EKW C-35. From 1939 - 1944, commissioned by the German government, the company produced watches for the Wehrmacht , Luftwaffe , and Kriegsmarine under the brand Revue-Sport.
The system monitors an aircraft's height above ground as determined by a radar altimeter. A computer then keeps track of these readings, calculates trends, and will warn the flight crew with visual and audio messages if the aircraft is in certain defined flying configurations ("modes"). The modes are:
An M14 mine, showing a cutaway view. The absence of a U-shaped safety clip and the location of the arrow on the pressure plate clearly shows that this mine has been armed. The top of an M14 has a simple arming indicator (an arrow embossed on the pressure plate) which can point to either A(rmed) or S(afe), giving a clear indication of its status.
