DESCRIPTION
Aircraft lighting power bus input to the FCC to adjust
brightness of pushbutton and panel nomenclature.
Input range is 0 to 34.5 VDC. Resolution of display
value is 34 mV per bit. Validity based on internal
Analog Valid.
Aircraft +28V/+14VDC power bus input to the FCC.
Input range is 0V to +34.5 VDC.
display value is 34mV per bit. Validity based on
internal Analog Valid.
Adjustment potentiometer located in the KEA 130A
altimeter used to supply a baro correction signal to
the FCC. The potentiometer has a resistance of 2500
ohms and is energized by a 4.0V reference supplied
by the FCC. Input range is 0 to 5V. Resolution of
display value is 4.9mV per bit. Validity based on
internal Analog Valid.
Motor voltage supplied from Trim servo and
monitored by FCC.
Resolution of display value is 65 mV per bit. Validity
based on internal Analog Valid.
Reference voltage supplied by FCC to power a baro
correction adjustment pot located in the KEA 130A
altimeter. Reference voltage is 4.0V ± 0.2V.
Resolution of display value is 4.9mV per bit. Validity
based on internal Analog Valid.
Internal reference voltage used to power analog
signal conditioning
Reference voltage is 15V ± 1.5V. Input range is 0 to
17.5V. Resolution of display value is 17.0 mV per bit.
Validity discrete is always '1'.
Internal reference voltage used to power analog
signal conditioning
Reference voltage is --15V ± 1.5V. Input range is
--25.5V to +5V. Resolution of display value is 30 mV
per bit. Validity discrete is always '1'.
Low--level analog validity signal supplied from the
VOR/ILS receiver. Amplitude is based on strength of
radio signal. The NAV deviation signal is considered
valid when this output is above 180mV. Input range
is ± 402 mV. Resolution of display value is 0.78mV
per bit. Validity based on internal Analog Valid.
Resolution of
Input range is ± 33.4V.
