I got a nasty-gram from Flight Safety with a nice 45 day notice and a PARP report that I can't really make sense of.
First, I know my ADS-B equipment is "not quite ready for new years." I'm using the G3X (non-WAAS) as the GPS source for an ADS-B out GTX 337R.
Here's the weird part... All 1521 reports of these values:
NIC - "Navigation Integrity Category"
NACv - "Navigation Accuracy Category for velocity"
SIL - "Source Integrity Level"
SDA - "System Design Assurance"
... all 1521 reports where "0" which is variously "unknown" or way out of limits.
NICp - "Navigation Accuracy Category for position"
... all 1521 reports came back as "10" or "<10m accuracy (WAAS)"
So, I plan to install a GPS 20A WAAS unit and see if this "fixes" it, but I can't really tell. Can anyone shed light on this, or done similar?
Thanks,
