SV-ADAHRS-200/201 Installation and Configuration

SkyView System Installation Guide - Revision R 5-5

It is important to calibrate magnetic heading in an area that has been verified to

be magnetically neutral. The presence of steel reinforcement (rebar), electrical

power lines under the tarmac, or other natural deposits of ferrous metals can

result in an inaccurate compass calibration. Airport compass roses are usually

verified to be magnetically neutral and thus are often a good location for

performing a compass calibration.

For more information on this issue see FAA Notice Number: NOTC4031:

https://www.faasafety.gov/files/notices/2012/Aug/CAUTION_TLP_031612_Rev10.pdf.

Use the following procedure to calibrate the SV-ADAHRS-200/201 compass:

1. Turn on the SkyView system and allow it to warm up for a minimum of 5 minutes.

2. Move the aircraft into position so that it is convenient to orient it in the four cardinal

directions.

3. Enter the Setup Menu on the SkyView display and go to the Compass Calibration Wizard

(SETUP MENU > HARDWARE CALIBRATION > ADAHRS CALIBRATION > COMPASS

CALIBRATION). Note - GPS data on the Compass Calibration Page must be green. If it is

red, GPS data is not valid.

4. Orient the aircraft to North, South, East, or West.

5. When the aircraft is stable at the chosen orientation, push the button indicating the

direction the aircraft is oriented in. Example – when the aircraft is pointed North, push

the NORTH button.

6. Wait for data collection to reach 100%.

7. Rotate to the next cardinal direction and repeat steps 4, 5, and 6 for any remaining

headings.

8. If there is a SV-ADAHRS-200 and SV-ADAHRS-201 installed, the Compass Calibration is

performed simultaneously. If the Compass Calibration fails on only one of the units, a

message will appear:

CALIBRATION FAILED – S/N xxxx

9. CALIBRATION COMPLETE appears when calibration is complete. Press FINISH to return

to menu navigation mode.

SV-OAT-340 Location and Installation

The SV-OAT-340 is designed specifically to work with the SV-ADAHRS-200/201.

For full redundancy, a second ADAHRS module requires its own OAT probe.

Probe Location

The SV-OAT-340 is an outside air temperature probe. In order for it work properly, it must be

able to measure air temperature accurately. Avoid exposing the probe to sources of heat that

would interfere with outside air temperature readings such as:

 Direct sunlight
