I currently own a 1941 Piper J5A that was manufactured without an electrical system. I do have foreflight with stratus for traffic (ADS-B in). I am currently exempt in selected airspace, which I am aware of. Anyway, on my flight from KOBI - KCGE Cambridge, MD today, I was close to entering the 60 NM vail of the DC SFRA. All of the sudden, I thought........can I enter that special area with an ADS-B exemption? I would’ve been slightly inside of it, but didn’t take the chance. I went to KGED instead. It’s tough to find the specific details for this. Any help would be greatly appreciated.
(i) Outside any Class A, Class B, or Class C airspace area; and
(ii) Below the altitude of the ceiling of a Class B or Class C airspace area designated for an airport or 10,000 feet MSL, whichever is lower
I wonder how they can track your speed without a transponder? Being a small fabric airplane, I don’t have much of a return without one. I would equipped it, if the allowed small battery powered units.
