I don't know what the fuss is. Those secondary minimums look OK.

Looks like Queenstown, NZ yeah. It is a tourist town in the mountains for doing skydiving, mountain biking etc. I guess that's like half of NZ's economy so not very insightful. https://goo.gl/maps/DKrefhAtfCejFVHc7

I mean, I flew into Pittsburgh last night and I couldn't see anything but the white glow and flashing of the navigation lights until we were like 20 seconds from touching down. I was in the aisle row though, so the ground may have been more visible if you looked directly down. I know when we took off the pilot says the visibility at our destination was half mile.

The whole point of instrument flying is that you can fly without visual reference to the outside. It doesn't matter if it's a sunny day or an overcast one or a blinding whiteout blizzard -- the techniques are the same and you can get where you're going safely.

On approach, when you hit minimums -- the point at which you either continue the approach visually or execute a missed approach -- you must be able to see the "runway environment" which includes Hi-Intensity Approach Lights. In the absence of HIALs, you typically need ceilings no lower than 250' AGL and visibility of 1 mile, but with them, you can usually manage 200'/0.5sm. Given a typical rate of descent on approach, that's not even 20 seconds. It's quite normal and no cause for concern. Given suitable equipment between the aircraft and airport, you can even manage well beyond that. It's eerie the first time you go visual near minimums.

Yeah, I knew the automatic systems would be fine, but it was eerie and definitely the least visible approach I've been on. It also took forever which made it feel all the more strange. At one point they said we would be down in 10 minutes and 15 minutes later we were still going. It wasn't like we did a go around either, for the longest time everything was just steady state with barely any perceptible change in direction, altitude, or speed. It was like we were in a twilight zone episode and entered some time traveling fog.

It's not even automatic, you have to demonstrate your ability to hand fly down to 200' AGL and then land, while dealing with a failed engine, on a checkride if the examiner wishes. When we do proficiency checks in the sim, we will set the clouds at minimums (if I'm feeling nice, I'll give you an extra 30 feet) and give you an engine failure on approach, usually at the least convenient time. If I'm feeling spicy, I'll pop the autopilot circuit breaker. That is the licensing standard. A standard approach to near minimums still feels like a drat miracle, but we train for the worst case.

We look at the clock and we look at the ETA time the computer gives us and I tell you that. Sometimes we get vectored around a little bit more. I regularly say the wrong city we’re descending in to so I occasionally spitball these times wrong.

I used to fly an airplane where the autopilot was too basic to do super low visibility approaches, so we hand-flew them using a HUD, and I think we were the only airline in the world to do that. Our minimums were 600ft horizontal visibility and a 50' ceiling, so an approach to minimums meant that the runway was visible for only a couple of seconds before touchdown, so you just had to trust that the HUD guidance was working properly. In the event you didn't see the runway and went missed at minimums, depending on how heavy the airplane was and how fast you added power, it wasn't unheard of for the main gear to skip off the runway. azflyboy fucked around with this message at 07:39 on Jan 24, 2023 |

My understanding is that the 737 can be hand flown to CAT III minimums if there's autopilot issues, but the usual procedure is to let the autopilot/autoland system do the work on those approaches.

That’s not an ILS, it’s an RNP approach. I’m like 99% it’s the RNP F approach at NZQN. RNP procedures are really cool; It’s a shame that for the most part, the FAA seems to be crossing its arms, humming, and pretending that it doesn’t exist.

RNP procedures also allow curved route segments, which can be used to maintain terrain clearance in places you otherwise couldn’t, or be used to shove an absolute gently caress-ton of airplanes through a remarkably small chunk of airspace. As someone with a remarkably small chunk of airspace, I’m super impatient for RNP to become available for SID/STAR procedure design in the US. It’s a really powerful tool.

The Queenstown approach is amazing. Fly from Auckland to ZQN and you get a 2 hr minitour of the whole country including Mt Taranaki, Farewell spit and much of the southern alps. Get a window seat on the left side of the aircraft.

We have a proprietary RNP approach where the missed approach procedure takes you down a fairly narrow valley, and in a worst case situation (single-engine missed approach in a heavy airplane on a hot day), you'll actually be looking up at the sides of the valley for a decent chunk of the procedure, but there's enough clearance for the FAA to sign off on it.

Get a window seat on the left side of the aircraft. It's no coincidence that Queenstown is one of the more fully modelled airports in MSFS. It's an iconic approach, quite possibly entirely unique in terms of procedures in the whole world. And, if you're a LotR fan like me, it's also interesting to note that there was a lot of filming in that area and just to the north. I really want to fly it in real life some day, even just VFR.

the "this buyout is good, actually" statement is as canned as it gets, I hope this purchase goes over incredibly poorly. there is literally nothing in there other than an implied 'fygm bye' from the owner.quote:"Joining forces with JETNET is the perfect match as we look to meet the business needs of our users while maintaining our enthusiast roots and unfiltered data. With a long history of providing highly valuable data to the aviation industry, JETNET offers the resources we need to accelerate our growth." lie to me better, buddy, this ain't it e: do i expect any potential protest to really affect the buyout, no - a lot of people feed commercial adsb already and I expect a lot will say gently caress it, what's one more. Especially when the inevitable strikes and adsbx starts offering member perks for feeding just like flightaware, etc, already do. Do I still think this is kind of bullshit all told, yes.
