G500 Components
The G500 is comprised of six main components:
• Primary Flight Display (PFD, left) and
Multi-Function Display (MFD, right)
• Attitude Heading Reference System (AHRS)
• Air Data Computer (ADC)
• Magnetometer
• Temperature Probe
• Dual Garmin GNS 430 GPS
The PFD (left) shows primary ight information in place of traditional pitot-
static and gyroscopic instruments, and also provides an HSI for navigation. ATP
procedures call for conguring the MFD (right) to display trac information.
The Attitude Heading Reference System (AHRS) contains tilt sensors,
accelerometers, and rate sensors to provide attitude and heading information
on the PFD.
The Air Data Computer (ADC) compiles information from the pitot-static system
and an outside air temperature sensor to provide pressure altitude, airspeed,
vertical speed, and outside air temperature on the PFD.
The magnetometer senses the earth's magnetic eld and sends data to the
AHRS for processing to determine magnetic heading.
The temperature probe provides outside air temperature (OAT) data to the ADC.
The dual Garmin GNS 430 GPSs provide input to the AHRS and PFD/MFD.
CAUTION: The GNS 430 and G500 units each have their own
databases. Navigation, terrain and map information on the G500
Multi-Function Display (MFD) may not be current and is not to be
used for navigation. Use the G500 MFD for trac information.
