Techincal Specification:
| ALTERNATING CURRENT VOLTAGE RATING IN VOLTS | 115.0 | | CONNECTOR MANUFACTURER CODE | 81349 | | CONNECTOR MANUFACTURER PART NUMBER | MS27497E20B35SD AND MS27497E20B35SC AND MS27497E20B35SB AND MS27497E20B35S AND MS27497E14B35PA | | FREQUENCY IN HERTZ | 400.0 | | FUNCTIONAL DESCRIPTION | THIS IS A DEVICE CONTAINING PRESSURE TRANSDUCERS, INTERFACE ELECTRONICS CIRCUITRY, AND A DIGITAL COMPUTER. IT RECIEVES IPUTS OF PITO ATATIC PRESSURE, ANGLE OF ATTACK, TOTAL TEMPERATURE, AND BAROMETRIC SETTING. THE DEVICE CONVERTS THESE INPUTS INTO DIGITAL DATA FOR PROCESSING. THE DIGITAL COMPUTER IN THE DEVICE CORRECTS FOR ERRORS CAUSED BY LOCAL FLOW AND CONVERTS THE DATA INTO DESIRED PARAMETERS. THIS PROCESSED AIR DATA AF ALTITUDE, AIRSPEED ANGLE OF ATTACK, MACH, TEMPERATURE, PRESSURE PARAMETER RATES AND VALIDITY AND SWITCH DISCRETES ARE PROVIDED TO OTHER AIRCRAFT SUBSYSTEMS VIA DIGITAL AND ANALOG OUTPUTS. | | INPUT INTELLIGENCE TYPE | AIR PRESSURE AND AIR TEMPERATURE AND ANGLE OF ATTACK AND ALTITUDE, GENERAL DATA | | INTELLIGENCE INPUT METHOD | AIR OR ELECTRICAL | | PHASE | SINGLE | | MOUNTING TYPE | RACK | | OUTPUT INTELLIGENCE TYPE | ALTITUDE AND ASTRO TRACKER AND TRUE AIR SPEED AND ANGLE OF ATTACK AND MACH NUMBER AND TEMPERATURE AND AIR DENSITY AND MAPS COORDINATES VOLTAGE | | POWER SOURCE | EXTERNAL | | REFERENCE DATA AND LITERATURE | 5F5-4-28-4 | | TERMINAL LOCATION | FRONT | | TERMINAL QUANTITY | 5 | | TERMINAL TYPE | CONNECTOR, PLUG | | TYPE/MODEL DESIGNATION | CPU-136/A | | UNPACKAGED UNIT HEIGHT | 6.940 INCHES NOMINAL | | UNPACKAGED UNIT LENGTH | 14.910 INCHES NOMINAL | | UNPACKAGED UNIT WIDTH | 6.200 INCHES NOMINAL |
