1.2 Equipment Description The Garmin GWX 70 Airborne Weather Radar is a microprocessor-based Line Replaceable Unit (LRU) that outputs weather radar data to an external MFD. The GWX 70 communicates with other LRUs via ARINC 429/453 and/or Ethernet high speed data bus (HSDB). CAUTION The operation of ground-based cellular telephones or other ground-based cellular devices aboard aircraft while airborne is prohibited by FCC rules. Due to the potential for interference with onboard systems, the operation of ground-based cellular communication devices while onboard an aircraft that is on the ground is subject to FAA regulations 14 CFR 91.21. FCC regulation 47 CFR 22.925 prohibits airborne operation of ground-based cellular telephones installed in or carried aboard aircraft. Ground-based cellular telephones must not be operated aboard any aircraft while the aircraft is off the ground. When any aircraft leaves the ground, all ground-based cellular telephones on board that aircraft must be turned off. Ground-based cellular telephones that are on, even in a monitoring state, can disrupt GPS performance. 1.3 Interface Summary The GWX 70 is designed as an open architecture system that uses ARINC 429, ARINC 453, and Ethernet communications interfaces.

Equipment Description
The Garmin GWX 70 Airborne Weather Radar is a microprocessor-based Line Replaceable Unit (LRU)
that outputs weather radar data to an external MFD. The GWX 70 communicates with other LRUs via
ARINC 429/453 and/or Ethernet high speed data bus (HSDB).
CAUTION
The operation of ground-based cellular telephones or other ground-based cellular devices
aboard aircraft while airborne is prohibited by FCC rules. Due to the potential for
interference with onboard systems, the operation of ground-based cellular communication
devices while onboard an aircraft that is on the ground is subject to FAA regulations 14
CFR 91.21.
FCC regulation 47 CFR 22.925 prohibits airborne operation of ground-based cellular
telephones installed in or carried aboard aircraft. Ground-based cellular telephones must
not be operated aboard any aircraft while the aircraft is off the ground. When any aircraft
leaves the ground, all ground-based cellular telephones on board that aircraft must be
turned off.
Ground-based cellular telephones that are on, even in a monitoring state, can disrupt GPS
performance.
