To riff on a common quote: if a million refugees want to get into your country and you don’t admit them, the refugees have a problem. If a billion refugees want in, you have a problem. Nothing “simply” about it.

Pitot and static tubes are irrelevant here. Would it trouble everyone to get a basic grasp of what we’re talking about before replying? I’m getting a little tired of constantly correcting basic stuff in the replies.

I didn't turn on the purchasing option. Seems pointless anyway, I always want to comparison shop things.

And yet when we considered the variables you mentioned, the conclusion didn’t change. What is the point of mentioning that decreasing household size could make the number misleading, when household size didn’t decrease by a significant amou

Presumably the AoA sensors are not required for that system to function.

by mikeash 7y ago
You don’t need to determine which is correct. MCAS is not a safety critical system and can just shut down if the sensors disagree.
907.
by mikeash 7y ago
My point is that it’s not mission critical. You can lose MCAS and be just fine. That’s why two sensors would suffice.
908.
by mikeash 7y ago
MCAS only exists to paper over a small handling deficiency. Apparently nobody (at least nobody with the power to force a change) thought that it could pose a safety problem. It’s not safety critical, so who cares if it fails? Except that it

First: I said it’s very unlikely, not impossible. Second: the failure of AF447’s pitot tubes was detected immediately and the system switched to an alternate law as a result; this contributed to the crash because the pilots were less famili

Can you elaborate on AF447? I’ve never heard of the AoA sensors being connected with that crash, and a quick search indicates that they were working fine.

by mikeash 7y ago
Airspeed is required for safe flight. The failure on that flight was detected immediately, it just couldn’t be handled. AoA on a 737 MAX is not required for safe flight and the system just needs to refrain from taking any action if it fails

If they’re damaged on the ground, surely it’ll be noticed that the sensors are claiming an extreme AoA while just sitting there, and they’ll be fixed. AF447 is an example of a fly by wire system that has to keep working no matter what happe

by mikeash 7y ago
If you get a reading of 20 on one and 34 on the other, you disregard both and disable the system. There’s a big difference between a system which must work and a system which must not go wrong. For example, the fly by wire system in an Airb

It’s not unlikely... because of some vague memory you have?

by mikeash 7y ago
The problem isn’t failure, but detecting failure. If the sensor had just stopped responding, there wouldn’t have been any problem. The planes would keep flying, the sensors would get replaced, and everyone would be fine. What happened was t

Except it wasn’t “whatever you did, don’t do that.” It was, “this looks weird, can you explain?” Followed by “OK, sounds good, carry on.” Then they got shut down.

If SpaceX’s Starship/Super Heavy (née BFR) actually pans out, it should be able to easily perform this mission.

I said it has "barely budged". A few percent in two decades fits that description. I don't understand why you bring up women entering the workforce again. As I mentioned, that's wrong twice: the proportion of women in th

No way is it possibly a new car every four years. There are over 200 million licensed drivers in the US and less than 20 million new cars sold per year.

Making up a story where your claim is true isn't very convincing. I can do that too: "I'll sell you this prime Florida real estate for a bargain price." "Can I see it?" "No. But it's definitely real!&

A 4% drop in average household size produces a 4% drop in median household income? That’s not a relatively big change, that’s a small change and exactly what I’d expect. Real per capita GDP rose by around 25% over this period. What accounts

It was originally intended to be a place of indoctrination into the state religion of the local theocracy. We have, fortunately, moved on.

Average household size went from 2.6 in 1999 to 2.5 today. How is that going to put a big dent in the median?
924.
by mikeash 7y ago
Average household size hasn’t changed much in the past 20 years. It’s down by about 4% in that time, so that doesn’t explain it. The percentage of the workforce that consists of women is also pretty much flat over that period, and in any ca

Agreed if we're looking at the whole world, but I thought we were looking at the US specifically.

by mikeash 7y ago
How about 1999 or 1989?

by mikeash 7y ago
Unfortunately, median household income has barely budged in the last twenty years.

The late 1920s. Fortunately, nothing bad happened after that.

Seems like you want to have it both ways. You want to argue for your choice of religion, tell us that we'd reach the same conclusion, and even go so far as to imply that anyone who claims to have gone through the process and reached a

I’ve heard of policies that cashiers are not to chase, let alone fight, but never that they’re not even supposed to ask someone to pay. Is that really true?
