SV-ADAHRS-20X Installation and Configuration
5-10 SkyView System Installation Guide - Revision K
When a pitot or static test is performed the ADAHRS is being exposed to dynamics that are
impossible to achieve in a real aircraft flight environment, namely, large airspeed changes
without the accompanying accelerations and rotations. This false condition will cause a well-
calibrated unit to incorrectly adjust its calibration. Furthermore, when a unit is in a test
situation a change in applied pitot or static pressure will cause the attitude to pitch up or down.
This is expected.
Performing the following Dynon-prescribed pitot and static test procedure to a Dynon ADAHRS
will prevent problems with the unit’s performance in flight.
Pitot/Static Test Instructions
Basic Principles
Ensure SkyView is warmed up during each test reading.
Unit should be powered off when changing pressures.
Keep aircraft still (do not move) when pressure is applied.
Procedure
1. Turn SkyView on and let it warm up for 5 minutes.
2. Turn ALL SkyView displays off.
3. Apply pressure to pitot and/or static port (keep aircraft still while SkyView is powered
on).
4. Turn on SkyView (external or internal battery power is acceptable. Only one display
need be turned on.)
5. Verify airspeed and/or altitude reading.
6. Turn ALL SkyView displays off (using button 1 is a good option for this operation.)
7. Repeat steps 3-5 for each pressure point.
