Altitude Inputs

The GTX 35R/45R uses pressure altitude inputs from several different sources:
• G3X ADAHRS (RS-232)
• The optional GAE module (Garmin P/N 011-03080-00)
Refer to section 3.9 for altitude source priorities. The Mode S transponder transmits altitude reporting in
25-foot resolution to ground stations and other aircraft.
