NOTE
GND mode is no longer supported by the transponder system. Always operate
the transponder in ALT mode while in controlled airspace, in accordance with
14 CFR 91.215(d). For guidance on transponder operation, refer to the FAA
Aeronautical Information Manual (AIM), 4-1-20(a)(3).
NOTE
Do not disable ADS-B transmission unless requested by ATC. Select STBY mode
to disable the transponder replies and ADS-B Out. Select ADS-B TX soft key to
maintain basic transponder functionality.
When on the ground or in the air, always operate the transponder in ALT mode, unless
otherwise requested by ATC. The transponder automatically determines whether the
aircraft is in the air or on the ground and sends that information to other aircraft and
ATC.
Refer to table 1-1 for mode selection key modifications.
Refer to figure 1-1 for 3X5/G1000 transponder soft key sections.
