I texted my conspiracy nut coworker about how I'd be dead today according to what he's proselytized for the better part of 2 years, and he said to "run and get some glutothione liquid form (???)", because it "cleans you [sic] liver and is a good cardiovascular detox." Sadly it was too late. I'd died like all the other vaxxed people exposed to the same frequency that's been used at airports for years.

No, you see, he got the math wrong. He didn't carry the crazy in one particular formula so now it's going to be another six months.

The 5g stuff is problematic because altitude radar systems work with incredibly small signal levels. They transmit a couple watts of power, and receive something like a millionth of that back to the receiver. They have been engineered to reject the out of band signals there were a few decades ago, and do that just fine. All receivers are sensitive to out of band signals despite everyone's best efforts. But the signals there used to be were just too small to punch through the filters of the old altimeters. The now scheduled 5g transmitters have an ERP of about 1500w. Although they're 200MHz below the radar altimater freqeuencies, such a strong transmitter will interfere with the very quiet radar signals. Filters need to be redesigned to reject such strong out of band signals. You can engineer a radar altimeter that can cope with it. But that was never done because it was never necessary, and if you would design it like that no one would buy it because it is much more expensive. Of course, if it's a recently made altimeter, they've probably been made with 5g interference in mind. In Europe, there's a bigger space between the altimeter band and the 5g band, so the practical issues don't exist here.

Interestingly there are restrictions on doing GPS RNP approaches when near an airport with the problematic 5G towers. Any one know why a purely GPS approach would be affected by this?

Any one know why a purely GPS approach would be affected by this? Because you’re still using radar altimeter data as part of the approach, specifically for MDA and DH, depending on exactly what approach you’re talking about.

Any one know why a purely GPS approach would be affected by this? Altitude accuracy is significantly less than longitude and latitude. For a sub meter GPS in lat/long height error will be over 2 meters vs mean sea level. Odds are the terrain you're over varies significantly from mean sea level and you'd be putting your faith in the gps ellipsoid approximation of the earth and the map onboard your aircraft being absolutely perfect. Even then you're off by over 2 meters which is going to be like 5% of a decision height in the best case scenario.

The only approaches we use the radar altimeter for are CAT II/III and some HUD specific ones. Unless the airplane is using the rad alt to derive some very narrow RNP values as part of a multi sensor thing we're not using it as part of our call outs or anything, its purely off of the GPS and Baro altimetery.

I don't see how that indictment could hold up though because the treaty is pretty specific in that you have to be onboard the aircraft? https://treaties.un.org/doc/db/Terrorism/Conv2-english.pdf quote:(b)Outside Special Aircraft Jurisdiction.— I guess maybe they're saying that they're an accomplice? But that'd mean that the pilots themselves were the hijackers and that makes no sense.

Unruly passengers are getting hammered with big fines, 10k to 55k. Not sure what a simple mask refusal will get, but anyone who gets fined also loses precheck.

Zero One posted:https://www.youtube.com/watch?v=mKN0SpWeILo That could be disastrously bad. It calls into serious question the quality of bonding of those panels, which directly affects lightning strike safety. In my experience paint quality and panel bonding quality tend to be correlated on aircraft. Corrosion protection is a direct trade off for panel bonding quality. I'd be checking the bonding tests they did with a microscope. Also the article mentions lighting strikes hit aircraft once per year, but that should be clarified to once per 1000 flight hours. Lightning strikes encountering lower than expected conductivity due to thick paint, poor bonding, or hitting carbon fiber rather than the mesh screen will increase (milliseconds matter here) the amount of time an area receives the strike and can greatly increase the damage to the aircraft. (e.g. structural holes, CF delamination, damage to electronics) Hopefully the A350 also has a second lightning/EMI/HIRF mitigation internal to the aircraft, not just that mesh. IIRC one of the Boeing composite planes has aluminum paneling and/or foil covering areas with cable runs. CarForumPoster fucked around with this message at 03:25 on Jan 22, 2022 |
