ADC
1. TAT COMBINED WITH MACH TO PRODUCE TAS AND SAT
2. CADC #1 GIVES SIG TO TAS IND ON P2 AND CADC #2 SENDS TO SAT IND ON P3
3. MACH NUMBER IS PROPORTIONAL TO IAS(=P DYN / P STAT)
4. CAS (COMPUTED AIR SPD ) = IAS ±SSEC (STATIC SOURSE ERROR CORRECTION )
5. TAS = CAS COMPENSATED WITH TAT
6. ELEC ALTEMETER GET CADC OUTPUT , IT HAS A ALT ALERT LIT
7. ASI GIVES A/S DEV TO A/THR SYS
8. A/S SCALE IS LINEAR FROM 60 TO 250 AND NONLINEAR FROM 250 TO 470
9. VMO (MAX OPERATION VELOCITY ) DEPENDS ON ALTITUDE
10. MACH NO IS 0.2 TO 0.999 DRIVEN FROM CADC
11. TAS IND SCALE IS 150 TO 650KTS ELEC SIG FROM CADC HAS A FLAG IF FAIL
12. SAT IND -99 TO 59
13. CADC REFERENCE EXCITATION IS 26VAC
14. P/S SENSED BY TRANSDUCERS CONVERTED TO ANALOGE DC
15. DADC ALT SIG HAS 2 PART FINE:EACH REVOLUTION IS 5000FT,
COARSE: EACH REV IS 135000FT
16. WA SIG (WRAP AROUND) APPLIED FOR MONITOR ALL OUTPUTS EXCEPT DIGITIZER
17. DADC CIRCUIT TEST: ALL LIT ON UNTIL REACH THEIR TEST VALUE
TAS
CAS 5KT
ALT 60FT ADDED
M BECOME 0.007
18. ALT ALERT SYS :
DEV EXCEED 300FT FLASHING LIT AND C CORD
APPROACH 900 TO 300FT STEADY LIT ON AND C CORD
RESET WARN ABOVE 900FT
INOP ABOVE 1600FT
19. L/G EXT INHIBITS THE DEV MODE
20. TEST SW ON P10 INHIBITES L/G EXT FOR GND TEST
21. ALT ALERT UNIT AND AURAL MODULE IS INSIDE P4
22. V/S WHEEL MOVES WHEN A/P NOT IN V/S MODE
23. ALT ALERT COMP PWR IS 26VAC AND 28VDC TAKE SIG :
BARO CORREC FROM F/O ALTM
ALT FROM ADC2
24. MACH A/S IN CADC IS 28VDC CONSIST OF:
MACH WARN SW
A/S WARN SW
GEAR DN DISPATCH
MACH A/S TEST ON P5
25. GEAR DN DISPATCH SW ON E2-1 :
NORM
GEAR DOWN : IF A/S MORE THAN 270KT AURAL WARN
26. ABOVE 24600 MACH IS LIMITED TO 0.92
