Section 1 - General

The airplane is equipped with a Garmin GNC 250XL GPS Navigator
with VHF COM, herein referred to as the "Navigator." The GNC 250XL
utilizes the Global Positioning System (GPS) satellite network to derive
the airplane's position (latitude, longitude, and altitude) and the
altitude digitizer to enhance the altitude calculation. The VHF COM
transceiver facilitates communication with Air Traffic Control.
Provided the GPS Navigator is receiving adequate usable signals, it
has been demonstrated capable of and has been shown to meet the
accuracy specifications of AC 20-138 for VFR flight. Navigation is
accomplished using the WGS-84 (NAD-83) coordinate reference
datum. Navigation data is based upon use of only the Global
Positioning System (GPS) operated by the United States of America.
