FEATURES
• GIA 63W (2) – The Integrated Avionics Units (IAU) function as the main communication hub, linking all
LRUs with the PFD. Each GIA 63W contains a GPS Satellite-Based Augmentation System (SBAS) receiver,
VHF COM/NAV/GS receivers, a flight director (FD; if the Garmin AFCS is installed) and system integration
microprocessors. Each GIA 63W is paired with the on-side display via an HSDB connection. The GIA 63Ws
are not paired and do not communicate with each other directly.
