"NO ALT" Message
My panel is the -12iS dual G3X package with a GPS175 navigator added. Recently, the last 5 or 6 flights, a "NO ALT" message appears occasionally over the transponder code. "NO ALT" is never on for more than 10 seconds at a time and "XPDR" is displayed the rest of the time.
I did pull a PAPR and in the Exceptions the NIC box was red.
Missing Elements has BAlt red with 3.51% fail, Max dT 0:00:11 and MCF 11
Integrity & Accuracy has the NIC box red with 16.92% fail, Max dT 0:00:23, MCF 26, AVG 7.4, Min 0 and Max 9
Are these acceptable error levels?
