For the next few days, my ADS-B out transponder (a Garmin GTX330ES) will be without its source of GPS info. Because I have too much time on my hands, and want to do some flying in the meantime, this generated several questions.
1. Will the transponder automatically cease broadcasting ADS-B out -- or will it be sending out incomplete data that runs the risk of annoying ATC, generating form letters, etc.?
2. If the latter, can it be temporarily configured to operate as an "old school" transponder? Obviously I would need to avoid areas where ADS-B out is required.
3. Under the often-ignored provisions of 14 CFR 91.215(c), all aircraft " equipped with an operable ATC transponder maintained in accordance with § 91.413" are REQUIRED to have that transponder turned ON in ALL "controlled airspace" (not just in airspace requiring transponders). On the East Coast of the US, basically everything is controlled airspace. If my ADS-B out transponder lacks GPS data, is it "inoperable" such that I can just turn the thing off (obviously avoiding transponder-required airspace)? Or is it still "operable" such that I have to come up with a way to leave it on? The reg suggests to me that I can't just declare something inoperable if it actually "works."
