So.... flying the other day, I apparently encountered a MLB TFR. This was in the lower section (<1,000') of the Hudson River VFR corridor. (Yankees won, BTW) Other pilots noted this on the CTAF when I made a position report, (but not when I was reporting APPROCHING it...) and a controller later confirmed when I called up for alternate route flight following. I was not on FF prior, and in 20/20 hindsight I will get on FF prior to the same flight in future and / or call the Approach controller for up-to-the-minute info. I was monitoring the local approach freq for my location and heard nothing. So I will file a NASA form, and have looked up the relevant NOTAM - FDC 4/3621, Oct 2014, a blanket NOTAM. Question one - I have read in other threads discussing the NASA form to NOT to admit to busting or a violation in the title / "Type of event / Situation" - Might I be OK wording it as "possible TFR encounter", or "suspected Airspace penetration" or what would POA suggest? I had a Lockheed-Martin / Leidos (or whatever it is this week) briefing for the flight & area 1 hr prior to wheels up, and specifically asked the briefer about any sports TFR's and got "None" There was a VIP TFR charted to the east which I noted to the briefer - I had checked the FAA's site and that was the only nearby red circle........ Called FSS when I was back on terra firma and was informed that it is Pilots' responsibility, and NOT FSS / FAA to see /know if there are any sports events in stadia with crowd > 30k persons. OK I get that now. I know the local sports teams and can check their schedules, but is there any reliable source for this info? What if I am in another less familiar area? Call the Local TRACON, Tower? Seems like a big possible hole in effective and critical knowledge notification. Whether the sports teams / venues call the FAA to let them know of an event or the FAA already HAS their schedule, that info WOULD be known by the FAA prior, so why not share it? Not making excuses, just seems like a broken link to me.... *I see that ForeFlight does apparently show stadium TFRs. I do not yet have an iPad or FF, but that certainly ads to the many reasons to invest in that.... * Also here..... https://www.aopa.org/go-fly/tfrs/stadiums-and-speedways How much detail would you include? Just the facts, Ma'am, or note times, the squawk codes I got later from the two major airports? I will note the Notam # and that I take this as a lesson in being better informed, aware of these TFRS and in using Flite Following esp. on flight into such tight airspace... SECOND - and not to sound too much like a Luddite - is it safe / confidential / anonymous to file the ASRS form on-line? Pretty sure I sent one in via USPS many years ago, but these new-fangled, hacker-prone computer things make me pause...... I suspect that no one gave this much / any official notice, but do want to be on record / file just in case... Certainly did learn a bunch with this. "Doveryai, no proveryai"
