error in the attitude estimation during these high dynamic conditions, but this error is
automatically reduced and eliminated even on dynamic conditions (provided limits are
not continuously exceeded). If this failure occurs in non-high dynamic conditions, unit
requires service.
Altimeter failure
When the altimeter in the unit is either out of range or not operating correctly the
altimeter tape becomes RED.
What to do?
If the altitude is within the limits of the unit (as quoted in the specifications), check for a
static port blockage. If the static port is not obstructed, the unit requires service.
Unit failure
When the PFD and HSI display modes show a RED cross the system is not operative.
This failure indicates that the sensor system on the unit is no longer speaking to the
symbol generator CPU.
What to do?
This problem can occur because the unit is configured wrong, because the software
on the device inside it has been erased, or because of an internal failure. The first
two causes can be solved by updating the software with the latest available software
version. If a software update doesn’t resolve the failure the Ultra requires service at
AvMap facility.
