INDEX
• GDC 74A (1) – The Air Data Computer (ADC) processes data from the pitot/static system and outside air
temperature (OAT) sensor. The ADC provides pressure altitude, airspeed, vertical speed, and OAT information
to the G950 System, and it communicates with the primary IAU, displays, and AHRS using an ARINC 429
digital interface.
• GTX 33 (1) – The solid-state Transponder provides Modes A, C, and S capability and communicates with both
IAUs through an RS-232 digital interface.
• GRS 77 (1) – The Attitude and Heading Reference System (AHRS) provides aircraft attitude and heading
information via ARINC 429 to both PFDs and the primary IAU. The AHRS contains advanced sensors (including
accelerometers and rate sensors) and interfaces with the Magnetometer to obtain magnetic field information,
with the ADC to obtain air data, and with both IAUs to obtain GPS information. AHRS operation is discussed
in Section 1.4, System Operation.
• GMU 44 (1) – The Magnetometer measures local magnetic field and sends data to the AHRS for processing to
determine aircraft magnetic heading. This unit receives power directly from the AHRS and communicates with
it via an RS-485 digital interface.
