|Why is the wind information not displayed or incorrect?|
sure all the components that make up the wind calculation are correct.
This includes: OAT, TAS, Ground speed, Heading, and Track.
|Why doesn't my ADC communicate with my GPS?|
that the input and output on both the ADC and the GPS are set
Correctly. Refer to the Shadin Avionics ADC-200 or ADC-2000
Installation Manual Loop Back procedure and the GPS Operating Manual
for details. For your Shadin Avionics Digidata, refer to the
Configuration section of the Operating Guide.
|Why is the fuel flow read-out inaccurate?|
that the K-factor setting programmed into the unit matches the K-Factor
imprinted on the side of the transducer. Refer to the Digidata
Operating Manual, Configuration Section 6 for detailed procedures.
|How do I verify the K-factor currently programmed in my unit?|
Digidata displays the K-factor by moving the toggle switch to
TEST/ENTER position and holding it there for ten (10) seconds. For the
ADC-200 and ADC-2000, refer to the Installation Manual Configuration
|How do I set the K-factor?|
to Section 10 of the install manual for the table indicating the proper
settings for the four (4) switches on the back of the ADC-200 and
ADC-2000. For Digidata, refer to the Operating Manual and Section 10 of
the Installation Manual for Drawing No. 4028-716. With the special
'loop back' harness, it's a simple 4-step procedure.
|How do I configure my ADC?|
are two (2) methods. Refer to the "loop-back" procedure in Section 9 of
the Installation Manual. The second method is the "adsetup" program
which can be accomplished through your PC.
|What is the difference between the ADC-200 and ADC-2000?|
ADC-2000 offers additional features of ARINC 429 output and automatic
baro correction with approved altimeters. Refer to the Sales Brochure
|What is the minimum level software version that communicates with the Garmin GPS? |
minimum software version required without a Shadin Avionics fuel flow
meter is 93.XX.61. If a Shadin Avionics fuel flow meter is part of the
installation, the minimum software level version is 93.XX.77.
|What is the difference between the ADC-200 and the Digidata?|
ADC-200 is remote-mounted, and displays airdata, fuel flow and winds
aloft information on a Loran/GPS. The Digidata is a panel-mounted
indicator that displays on the Loran/GPS as well, so you can always see
fuel flow data without changing pages on your GPS.
|Why does the winds display shows dashes after I've been in a turn or accelerated or decelerated?|
the aircraft has been in a turn, or has accelerated or decelerated, the
winds information dashes out after holding the last valid wind
information for three (3) seconds. The winds information will again be
displayed continuously when the aircraft has maintained a steady course
and airspeed for at least forty (40) seconds. If heading and magnetic
track differ by more than 40 degrees, no wind information will be
|How is the head-or tailwind calculated?|
- This component is derived from the difference between ground speed and air speed.
|How is True Air Speed (TAS) calculated?|
- Indicated Air Speed (IAS) and Outside Air Temperature (OAT).
|My aircraft is 28 VDC and the transducer is 12 VDC. Is this OK?|
- Yes. The Shadin Avionics Airdata Computer steps down the voltage and provides it to the transducer.
