2.5 Pressure Altitude Broadcast Inhibit (PABI)
Pressure Altitude Broadcast Inhibit shall only be enabled when requested by Air
Traffic Control while operating within airspace requiring an ADS-B Out compliant
transmitter. PABI is enabled by selecting the GTX to ON mode.
2.6 Datalinked Weather Display (GTX 345 Only)
Do not use datalink weather information for maneuvering in, near, or around areas
of hazardous weather. Information provided by datalink weather products may not
accurately depict current weather conditions.
Do not use the indicated datalink weather product age to determine the age of the
weather information shown by the datalink weather product. Due to time delays
inherent in gathering and processing weather data for datalink transmission, the
weather information shown by the datalink weather product may be significantly
older than the indicated weather product age.
Do not rely solely upon datalink services to provide Temporary Flight Restriction
(TFR) or Notice to Airmen (NOTAM) information.
2.7 Portable Electronic Devices
This STC does not relieve the operator from complying with the requirements of
91.21 or any other operational regulation regarding portable electronic devices.
