Another fun dewpoint related bit of trivia: In 2006, the FAA accidentally put out a legal opinion that would ground small airplanes any time it was humid and cold.

Someone had asked an FAA office for a definition of "known icing" conditions (which is generally described as below-freezing temperatures and visible moisture), and the FAA somehow decided that "known icing conditions exist when visible moisture or high relative humidity combines with temperatures near or below freezing" was the correct definition.

The problem with that was the fact that "high relative humidity" is very vague, and there aren't actually any aviation weather reports or forecasts that give relative humidity, so that definition was not only virtually impossible to follow, but it meant that technically, aircraft without approved deicing equipment couldn't fly any time it was humid.

Predictably, the aviation community reacted with a collective "WTF?", but since the FAA moves as fast as a tranqulized turtle, it took the agency two years to officially put out an "oops, our bad" legal opinion that went back to the old definition.

I was flying into SFO in Dec 2019 and a whole ton of flights were just scrubbed completely because of the wind, it hosed up the travel plans bigtime. And with all those cancelled flights it had a hellacious ripple effect.

Abnormally windy for the area. Felt a bit like a Nor'easter rolling in just without the precipitation. SFO was averaging ~45 MPH (gusting to 53) from the NNE most of the day. Only getting ~25 MPH (gusting to ~30) where I'm at, but I'm 30 miles South and inland from the Bay.

Do they ever close the bridges across the south bay for wind, especially for large trucks?

That explanation seems odd to me, since the airports I'm familiar with deactivate badges that are reported as lost/stolen, but it's very possible that the airport somehow didn't do that, or the guy just piggybacked through doors or there were doors that didn't need a badge scan to get through.

Somebody posted on reddit where the employee vending machines are located at MSP. The machines are a fraction of the price of the public machines. The only thing securing them is a sign on the door.


>a lot of people get upset at the lack of food if you're stuck here past 9pm. Along with the lack of a comforting and quiet place to sleep or relax. Most people live off of vending machine snacks or overpriced candy bars for the night unfortunately.
>
>Food- There is a sandwich vending machine behind the prince store that people don't know about and never gets used. Its priced for employees, so prices are 50% of what the normal ones charge. To find it, go to the prince store right across from stone arch restaurant. Go behind the prince store where you see the cutaway and where the REAL ID station is at. Make a right and go through the doors that say "Authorized personnel only". You can go through these doors, you just can't use or access the elevator in this room. The doors are propped open 75% of the time anyways. All of the vending machines are employee machines so the prices are slashed in half, along with the sandwiches.

>Comfort- Go to the mezzanine level (floor 2) once youre inside security. All of the vending machines up here are also employee prices that the public are allowed to access. Up here you will see "Quiet rooms" that have sleeper cushions for anyone to use, and its a quiet comforting space with doors that not everyone knows about. The rest of the upstairs is all office space. Don't go into any of the other rooms up here unless they're specified for the public.

That's fascinating because I've never, ever seen an approach like that in Canada, where you have to be visual but still follow waypoints.

I'm not certain if they ever close them (I very rarely cross them so I don't keep tabs.). A quick peek does show that they advise to slow down when wind speeds reach 30 MPH but no mention of a past closing.

I checked with a lifelong local guy who drives a delivery truck around the Bay area. He's never heard or experienced any of the bridges being closed. They've either never had a truck pushed over or it's too rare to enact a no crossing warning.

High wind warnings/closings were a thing when I lived next to the Chesapeake Bay Bridge. Having a box truck blown into the water wasn't uncommon, even with warnings being given.

Not sketchy at all. It doesn't mean you can't go around, it just means there's no prescribed procedure for what to do after, like an instrument approach has. So you fly a regular pattern, or (far likelier) vectors from ATC. This is the case for every visual approach, thousands of which are flown every day in airline ops.

Charted visual approaches are relatively common in the US, but I’m not sure how many have specific GPS waypoints versus “fly this altitude to the river, then turn final over those power lines”.

A few years ago, SEA used to use a pair of charted visual approaches (the Husky and Bay visuals) all the time when the weather permitted, but once the airport got slammed with traffic from the Alaska/Delta dick-waving contest, they basically abandoned them innvzcor of just vectoring everyone.

I never forget a face, but in your case I'll be glad to make an exception.
Been watching KC-135s orbiting DC the past couple of days. Yesterday saw one pass at 24,000 ft linked up with an F-16 that peeled away a minute later after topping off. Just caught another pass this evening and saw another departing fighter with afterburners lit. Not sure if this always happens or if this some air patrol operation surrounding the inauguration.

That was actually another question I had. Yesterday I tracked two E-6b Mercury flights in the area and the KC-135s over DC all morning then this afternoon the 135s went dark despite them passing overhead every 10-15 minutes. Are the planes choosing to broadcast intermittently or is this on the part of FR24?

Haven't lived in DC for a while, but right after 9/11 the same thing was going on, with refueling happening low enough that you could watch it. Then it went away after a few months, so I would guess its cover for the inauguration to avoid a Tom Clancy scenario.

as I understand it they are always broadcasting - flight controllers still need to know where they are - and it's up to the website to choose whether or not to block it for casual viewing based on whether or not they care about ADS-B privacy

It's uncommon but not unheard of for KC-135s to do a racetrack around/over DC.

The only time they're not is when they're out off the coastline away from an ADS-B receivers. The E-4s are trackable as well - just look for military B742s with callsigns like GORDO and NIGHT. The VC-25s usually show up as "82-8000" or something, but never AF1. AF2 *will* show up as that callsign, though.

My brother flys P-8s and I want to say they they will turn theirs off if not in congested airspace, but I could be wrong there. I’ll need to double check. Granted If they’re off on a sub patrol they don’t have much interest/need of broadcasting their location.

Presidential or other important TFRs sometimes have fighter coverage, but not always. I've managed them from AWACS or ATC facilities, and never had to do more than make a few calls on guard to give a moron a vector, to a location where he will be met by men with badges in dark suits.

Another possibility might be if they don't have to broadcast in military airspace. I don't know if that's a thing or not, though.

That gave me a vague memory of a story where something was going on and a fighter pilot just did a high speed low pass over the crowd and settled it down. Granted it may shatter windows for miles, I wonder how effective something like that might be towards big mobs.

I was woken up by a very low flying heli today again that circled my neighborhood twice. I didn't see it, but Apaches and Blackhawks have done so off and on this past year. It's super awesome, but also pretty intimidating seeing a military aircraft low and seemingly interested in you (I live in a rural area not far from Lewis/McChord, so it gets frequent traffic).

Pretty sure show of force passes were pretty common in Afghanistan. Nothing says “we’re not loving around” like a pair of A-10s or Apaches going over your head.
