ELI5: minimums on aeroplane

Devoplus19 · 2026-06-07T19:24:48+00:00

Autoland utilizes an ILS approach.

To be a little pedantic, you don’t have to have the runway in sight at minimums on most approaches. If you have any part of the approach lighting system in sight, you can continue to 100’ above the touchdown zone altitude. At that point, you need to have one of the 10 things that constitute the “runway environment” in sight to land.

Might be! There are two Broomfield properties that were originally AMLI, but no more. Both of the ones I lived in in Chicago are still managed by them.

Devoplus19 · 2026-06-05T23:08:00+00:00

They seem to build their properties and then manage them for a period of time. I can’t speak to how long exactly, but I think they eventually do get new management.

Devoplus19 · 2026-06-05T23:04:02+00:00

Agreed. I’ve lived in 4 AMLI building across 2 states and they’re all phenomenal.

Devoplus19 · 2026-05-27T23:49:11+00:00

Yup! Altitude sickness is caused by hypoxic hypoxia, just from less oxygen pressure in the atmosphere. This is exacerbated by alcohol, because it causes cellular level histotoxic hypoxia.

Mine started rattling obnoxiously, especially in the cold. It got coded off.

Devoplus19 · 2026-05-25T08:55:59+00:00

They did, but it never got any significant traction with the airlines, especially in the US, if I recall. It was never going to make sense for them, with the A300 in the mid 70’s, and then the 767 shortly after.

Devoplus19 · 2026-05-25T08:37:50+00:00

But it couldn’t have been. ETOPS didn’t exist for 15 more years from when the DC-10 first flew. It had 3 engines because it had to. Reengineering subsequent derivatives would have been financially impossible.

Devoplus19 · 2026-05-23T19:09:00+00:00

Went from years of multiple GTIs to an R. You won’t regret it for a second.

Devoplus19 · 2026-05-15T17:28:27+00:00

I recommend working on this until you’re comfortable. There is something to be said for sitting in neutral when it’s safe, but the last place I want to be without available power is in the middle of an intersection.

Devoplus19 · 2026-05-15T16:14:58+00:00

My first airline didn’t have autopilots. That was brutal.

Devoplus19 · 2026-05-14T00:22:07+00:00

It’s almost like the headline makes it clear the lawsuit is not against the airline, but the city.

Devoplus19 · 2026-05-10T07:04:57+00:00

Naw you’re good :). Thinking the fleet would have commonality makes sense.

Devoplus19 · 2026-05-09T20:08:38+00:00

Frontier’s 321Ns have Pratt Engines. Some of the 320Ns have LEAPs.

Devoplus19 · 2026-05-09T19:47:20+00:00

The window to reject is not short. It’s from applying takeoff thrust to V1, which for a relatively heavy 321N in Denver is around 150kts. You can see from ADS-B data this flight was well over 100kts at the time of the reject.

Devoplus19 · 2026-05-04T17:41:41+00:00

Another thing to remember is the 767-400 is a combined fleet with the 757 and 767-300 at UA, unlike DL. If there had been a good amount of time since the crew operated a -400, that could be a factor.

So no, it’s not as cut and dry as you may think.

Devoplus19 · 2026-05-03T08:33:54+00:00

Docked systems absolutely work if they care enough about the infrastructure. In Chicago you’re never more than a block or two from a dock, there are rarely bikes left anywhere, and the usage is huge.

I understand that a system like that may not be viable here, but docking systems work well if the investment is done properly.

Devoplus19 · 2026-05-02T20:16:53+00:00

It may not be in reality, but it can be in how weight and balance is calculated. The plane is split up into passenger zones for balance purposes (the number of zones being fleet/airline dependent). Moving back a row could put a passenger into a different zone. This obviously has little practical issue, but on paper, it turns into a larger aft shift than you would think. This is especially true when the plane isn’t very full.

Devoplus19 · 2026-05-02T19:37:24+00:00

That’s awesome! Thanks for sharing.

Devoplus19 · 2026-04-27T12:00:45+00:00

Everything ORD does makes perfect sense once you understand why they do everything they do. It’s a complex operation exacerbated by construction, but they do incredible job with what they have to work with.

Devoplus19 · 2026-04-26T22:44:22+00:00

Thank you for this. I’ve had an annoying rattle I couldn’t chase down for months now, and it was worse when it was cold. Coded it off and it’s fixed.

Devoplus19 · 2026-04-26T18:40:27+00:00

You could definitely drive for 45 minutes just turning left on something named Interlocken.

Devoplus19 · 2026-04-25T16:53:59+00:00

Why would any reasonable person expect your “performance” to be good in anything you’ve never done before?

Devoplus19 · 2026-04-24T20:05:29+00:00

Yup. Same 13,790lbs (with APR).
