All that sounds fantastic. Shame about the dudes who don't fly with a radio at all, or just switch them off even if they have them installed.

Plus we’re (airlines and the better biz jets) are gonna get more into cpdlc and datalink stuff so there will (hopefully) be less talking on the radio anyway.

I was wondering if that would help dodge this problem entirely. Something like that would be the correct solution. Despite the mil having infrastructure to send texts etc or datalink voice, it looks like it'll be decades before being adopted on a wide-enough scale, since most platforms don't support it beyond sharing position and tactical info.

I love the little creature comforts of CPDLC. When I go to leave my base airport I just hit a few buttons and sit back while the FMS grabs my weather and clearance.

The Federal Aviation Administration: Bringing you yesterday's technology, tomorrow! I'm super excited for enroute CPDLC. Two of our busiest sectors have average on-frequency times under five minutes, which means frequency congestion is pretty much the limiting factor there. Anything that gets an airplane off my frequency is an enormous advantage.

Dominoes posted:Hey bros. Can you think of a reason we don't have clever post-processing for radios so human voices are amplified and noise is reduced? There are different levels of sophistication that could be used. My #1 guess is processing isn't quick enough to be effectively real-time. Could approach with traditional signal-processing techniques, machine-learning, Fourier analysis to reconstruct voices etc. I looked up the datasheet for my headset and the speakers are optimized to only reproduce sounds from 350 to 3000 hz, which is the range that most human speech falls into. That's a pretty drat simple way of making sure that voices are more prominent than noise. You could also do something similar with a simple analog filter that passes the target frequencies, which I imagine all radios already have. For anything more advanced, like your suggestion of using machine learning to pick out the words, I think the human brain is orders of magnitude better than any technology we currently have. Even a toddler can easily follow one specific conversation in a crowded room, but my phone's voice recognition system, which has been trained specifically to my voice, will happily inject words coming out of the TV even if I've got the phone right up to my face.

This is called the “cocktail party effect” if you want more info and it’s actually amazing how good humans (and some animals) are at it. https://en.wikipedia.org/wiki/Cocktail_party_effect?wprov=sfti1 I worked with a professor that mainly researched signal processing for this type of thing and it’s one of those things humans are good at that computers are completely terrible at.

Because the current system uses reliable proven technology, works well enough %99.99 of the time, and most importantly, has already been paid for. Also with CPDLC becoming more and more of a thing it's largely a moot point at least for the airlines.

I just hope enroute cpdlc in the US doesn’t end up like in Canada where it goes like this: CPDLC message: contact center on 123.45 *3-4 button presses to acknowledge message* Voice contact: center XYZ heavy on 123.45 Voice contact: XYZ heavy, roger *10 minutes later* CPDLC message: contact center on 123.5 Rinse repeat x10 more times across the country So you’re making tons of fmc inputs to acknowledge just to change center sectors, not to mention if you want to change your route or altitude, where a single mic press would accomplish the same thing most times.

So I had what was probably the most somber overnight (overmorning, gently caress redeyes) today. We were at BDL and could see the b-17 crash site from out hotel. The lobby of the hotel had a bunch of news crews, people in NTSB wind breakers, and a presentation by the state police where they announced the names of the victims. It felt so strange to be walking through the hotel in uniform amongst all that like "yep, just gonna go fly where a bunch of people died in a plane a few hours ago."

Fuuck  Reminds me of the evening after the Reno crash in 2011, walking around the casino/hotel with all the typical casino lights/sounds, but with all the bleary eyed people who had clearly also been there. And still live coverage on all the TV's.

e.pilot posted:There’s no ground above you There might be planes, though. I work at one of the only airports in the nation with an ILS procedure which may require a descent as the first maneuver when performing a missed approach. Once, a UPS 767 chose to level off at 1900' contrary to ATC instructions when performing a missed approach there. ATC instruction was, as published, to track the localizer and descend to 1500'. The final approach fixes for the ILS approaches into SeaTac are at 1900', directly overhead Boeing Field. They got lucky. a patagonian cavy fucked around with this message at 05:59 on Oct 4, 2019 |

cigaw posted:Looks like it would only apply if executing an early missed, though. An important distinction for sure, but how common is that unless you're full-scale deflection? This is an honest question, I’m unfamiliar with big boy ops, all I do is take it down to minimums in day VFR on a dinky 172. Depends on company ops specs for stabilized approach criteria, among other things.

This is an honest question, I’m unfamiliar with big boy ops, all I do is take it down to minimums in day VFR on a dinky 172. Early missed approaches can also happen if the spacing between aircraft gets too close (usually from a pilot failing to follow a speed restriction closely enough), if the preceding aircraft doesn't clear the runway in time, or if there's vehicles on the runway that don't quite exit when they're supposed to. On the Q400, most of my early missed approaches have been in CAT III weather when the required interaction between the HUD, three different nav radios, and IRS doesn't quite go right, and the airplane stubbornly refuses to go into the proper mode by the time we hit the final approach fix. That said, missed approaches of any type are somewhat rare in the airline world, and I maybe fly 3 of them a year, out of 400 or so legs I'll do.

In 5,000+ hours of airline flying over 8 years I have never gone missed because we arrived at minimums and not seen the runway. All of my missed approaches have been due to insufficient spacing between aircraft or the approach being unstable. It doesn't help that the pavlovian response to someone saying "go around" is to hit the TO/GA buttons and start climbing which us going to get you in trouble if you're already above the missed approach altitude.

The last maneuver was a power off 180/simulated engine failure in the pattern on the DPE acting as a student with no prior notice that's what we were going to be doing. Talking him through that to his satisfaction was uh, trying. E: in hour 8 of the checkride.

I haven’t given an hour of dual in like 15 years but there I am doing the FIRC every other year because I’ll be damned if I ever let that thing lapse. 8 hours with an FAA examiner at a FSDO that had (has) a 90% failure rate. poo poo gave me PTSD.

My CFI lapsed because the Berkshire Hathaway company I worked for at the time refused pay me enough to keep it current (or have health insurance or have decent housing or-) My understanding is that if/when I do get it reinstated I can do the check ride with a regular DPE seeing as it won’t be an initial CFI check. Confirm/deny?

https://twitter.com/WDTN/status/1182398838407094273 I recruited the student. The CFI has become one of my best friends. They got out OK, but I can't get over the initial shock of realizing where geographically the plane was, that it was highly likely it was one of ours, and the uncertainty (until we found out they were fine about 20 minutes later). I'm a mess.  Two current and two former/part-time CFIs and I went to dinner after spending several hours at the airport. I needed that because I really didn't want to go home. e- Jesus Christ, they just showed it at halftime of the Giants/Patriots game on my local FOX affiliate. I mean, I get that was a possibility but it didn't cross my mind.
