M14-04

Function of M14-04 in onboard recording systems

The main function of M14-04 is conversion and matching of sensor signals for further recording by onboard flight data acquisition equipment. The module may process analog signals from aircraft sensors and convert them into a normalized DC voltage that can be received and encoded by the recorder. This allows flight parameters from different primary sensors to be brought into a standard signal format for registration. Correct operation of the module is important for reliable recording of flight, navigation and aircraft attitude data.

Signal conversion role of M14-04

According to the source context, M14-04 can work with sine-cosine AC signals from SKT / SKVT-type angular position sensors. These signals may relate to heading, roll, pitch or other spatial-position parameters depending on the parent system. The module converts or coordinates these signals into a normalized DC output range used by the analog-to-digital conversion circuits of the flight data recorder. Exact input levels, scaling coefficients, channel assignment and connector pinout should be checked by the applicable equipment documentation.

Application with BUR-4-1 and BUR-SL equipment

M14-04 is referenced as a module used in flight information acquisition / recording equipment such as BUR-4-1, BUR-SL-1 and similar onboard systems. It may be installed as a removable printed-circuit module inside a cassette or base block of the recording system. The module may also be associated with aircraft such as An-72P, M-101T and Mi-family helicopters, depending on the equipment configuration. Applicability must be confirmed through the aircraft equipment list, recorder documentation and module slot assignment.

Related sensors and recorded parameters

The module may be used with sensors that provide flight and aircraft-state information to the recorder. The supplied context mentions speed sensors such as DSPM-2, barometric altitude sensors such as DVoP-13 and DDIA, and linear acceleration sensors such as MP-95. These references should be treated as system-context examples rather than automatic direct compatibility for every installation. In practice, the exact sensor-to-module connection depends on the flight data recorder version, aircraft type and wiring documentation.

Identification and ordering of M14-04

Before ordering M14-04, the customer should confirm the parent recorder, aircraft type, required version, quantity, condition category and documentation requirements. The module may be required for replacement of a defective recorder channel, repair of BUR equipment, bench testing or spare parts stock. Since modules from this group are often supplied from storage, it is important to check factory packaging, product passport, preservation status, serial number, production date and bench-test records if available.
