provides a break-down of EASA AMC 20-24 requirements and corresponding compliance statements.
For installations that utilize a Garmin GNS 400W/500W series, GTN 6XX/7XX series, or GNS 480 device
(collectively referred to as 'Garmin GNS equipment'), no additional data is required for the compliance
matrix. Compliance statements are pre-populated for all aspects involving GNSS position source
requirements.
If a non-Garmin GPS position source is used, the installer must:

2) Obtain and input the appropriate data into the compliance matrix:
a. Item 14, Horizontal Position and Horizontal Position Quality Indicator(s)
b. Item 17, Horizontal Position Source Accuracy
c. Item 18, Horizontal Position Source Integrity
d. Item 19, Horizontal Position Source Integrity - Source Failure Probability
e. Item 20, Horizontal Position Source Integrity - Alert Failure Probability
f. Item 21, Horizontal Position Source Integrity - Time to Alert
g. Item 26, GPS Engine and GPS processing design assurance levels
h. Item 28, Horizontal position data latency requirements
i. Item 53, Position source minimum requirements
j. Item 55, Alternative means of establishing integrity containment radius(if not
provided by the horizontal position data source)
k. Item 58, GNSS position source TSO compliance
l. Item 59, Identify whether the system incorporates Fault Detection and Exclusion
