14 Troubleshooting

The following steps are to aid in identifying installation or unit performance
related issues:

Table 8 - Troubleshooting

Issue

Possible Reason

Power

Unit does not power-on

Check associated breakers

Ensure aircraft battery is greater than 10 VDC

Check wiring and pinouts

Unit will not shut off, even if power is
removed

Ensure no pitot or static blockage or line kinks are present
(locking pressure and airspeed indication over 40 knots)

Stabilization

Unit will not stabilize and aligning
annunciator remains on

Return to factory for service if unit does not align within 3
minutes of power-on

DG drifts more than 30 degrees per
hour

Make sure you are running the newest software

Complete Gyro Cal

Battery

Battery indication shows FAIL

Contact uAvionix support

Trim

Roll, Pitch or Slip show small but
constant error

Ensure unit is level in panel (using a bubble level or similar)

Set trim adjustment in Installation menu. See Installation
Manual for instructions

Airspeed or Altitude shows small but
constant error

Set trim adjustment in Installation menu. See Installation
Manual for instructions

Interface

GPS information is expected but does
not show up in data overlays

Check GPS input is configured to match the connected GPS
serial data type and speed

Set direction indication to GPS TRK

“NO DATA” is shown

Check interface cables and pinouts

“NO GPS” is shown

Check GPS input is configured to match the connected GPS
serial data type and speed

Alerts

Audio alerts not heard over the audio
system

Check wiring and ensure alerts are enabled in the Setup
menu

Ensure unswitched input is available on the audio panel

Verify volume setting is sufficiently high in the Setup menu

Nuisance alerts are generated

Ensure alerting limits are configured as desired in the Setup
menu

Disable any undesired alerting features in the Setup Menus.
