I can’t say for certain on your system, but generally on the G1000 system to load a Tango airway you would load the entry and exit points. After loading the points, highlight the entry waypoint and press “Menu” > “Load Airway” > scroll to TXXX”
John, can you pass along what you learned? I haven’t had a Tango route yet, but it sounds like a good thing to know how to enter.
Thanks,
Robert
PS: is your G1000 WAAS upgraded or the original? I know that the WAAS upgrade also included a software update and was wondering if that added T-route support.
