And that's exactly why you don't just want to rely on TSO-compliant GPS receivers. They only receive GPS on one frequency, and have sub-par jamming resistance.

@@MarianKeller What are some good ones you recommend?

I know this is probably a joke, but in case it's not, there are GPS outage NOTAM's almost constantly. If you figure out a way to understand when they're actually going to affect you then please let me know.

@@sleepyhorses6100 It wasn't a joke. There isn't any way to decode if the NOTAMs will actually effect your flight; all you can do is assume that it will and plan accordingly.

@@joebloggs8785 ok well I guess you should assume your GPS is going to fail every single flight. I fly near 1000nm legs every week and there are always GPS NOTAMs listed along my route. Maybe 2% of the time I actually have an issue, yet ATC seems to know exactly when they’ll happen. It is NOT obvious via the NOTAM and attempting to decipher each and every one of them, of which there are probably a dozen, is a waste of time given how sporadic they are. Here is just one of many along one of the routes I fly. Keep in mind that this is about 75% of the way down on a list of several thousand words worth of NOTAMs, most of which are irrelevant to my flight: KZFW GPS 01/021 ZFW NAV GPS (FTPKLA GPS 22-01) (INCLUDING WAAS, GBAS, AND ADS-B) MAY NOT BE AVBL WI A 264NM RADIUS CENTERED AT 311155N0930619W (AEX 261031) FL400-UNL, 216NM RADIUS AT FL250, 151NM RADIUS AT 10000FT, 106NM RADIUS AT 4000FT AGL, 56NM RADIUS AT 50FT AGL.

yes

yep!

I SWEAR this was unplanned... but also, I have since learned what caused it!

@@austinmeyer you seemed so calm/undisturbed after the 100% loss of GPS in flight that's why i thought this was a planned test. I believe some of these devices support multiple constellations (the non TSO ones) I'm curious what caused the total outage..

@@asho1735 Eh. Easy to be calm in day VFR where I fly all the time. OK. Outage caused by: THE LAV MICROPHONE. Crazy, but true. Every time I set up for recording, the GPS went out. True story. Took me a while to figure it out.

I dont. Some do. De-ice slows you down a bit my disrupting wing airflow. Soooooo... no good for me.

​@@austinmeyer Thanks for answering, I have been looking into personal aircraft and found LancAir because of one of your videos but could not find the answer on De-ice so, i thought i would ask you since you own one. By the way i Love your pure Geeky passion you have for this stuff it is refreshing seeing someone on KZfaq that isn't fake.
