Falcon 10 Autopilot Drama

Falcon 10 N100CU

 

Pitch bump started, May 2022. Swap vg.  That solved it for months.

Pilots report all good.

Swap airdata controller. (Back to original position)

Hum in headsets

 

Stuck mic.  Seemed to start pitch bump problem.

Mar 2023.   Shutter pitch, humming headphones, could not hear atc. Stuck mic.

after finding burned plug at RH lav:
#1 FD/AP will not capture altitude, but (sortof) will track altitude

#2 FD will not GA.  RH GA will clear HDG select button, will not clear ALT select button.  When RH GA is held down, RH Vbars will go to 0 pitch or lower, then disappear when G is released.

GA mode block diagram Falcon 10

inputs to the mode coupler seem similar left side to right side.

WD notes from Nov 2023.

 

 

 

Collins manual that shows the difference between 590A-3H, and 590A3K

1.5.16 590A-3H Air Data Contro l
The 590A-3H Air Data Control supplies an analog error signal to the flight control system that is propor-
tional to altitude error. True airspeed, indicated airspeed, and altitude programming voltages are also gen-
erated for flight control system use. The altitude error gain may be programmed with true airspeed, indi-
cated airspeed, or altitude, or set at a fixed value. The 590A-3H also provides signals for altitude preselect,
vertical speed hold, indicated airspeed hold, and Mach hold. The 590A-3H is contained in a 318-ATR short,
low case and weighs 2.09 kg (4.6 pounds).
1.5.17 590A-3J/3J1 Air Data Co ntrol
The 590A-3J/3J1 Air Data Control supplies to the flight control system an analog error signal that is propor-
tional to altitude error. True airspeed, indicated airspeed, and altitude programming voltages are also gen-
erated for flight control system use. The altitude error gain may be programmed with true airspeed, indi-
cated airspeed, or altitude, or set at a fixed value. The unit is contained in a 3/8-ATR short, low case. The
590A-3J weighs 2.00 kg (4.4 pounds) maximum. The 590A-3J1 weighs only 1.5 kg (3.3 pounds).
