I’m filing this as a corollary of “only break one law at a time”. Yeah the book said that he could make this flight, but it was so marginal. He should have loaded less fuel, period.

The only reason boeing is selling anything right now is because airbus’ factory production is bought out for the next decade. People are *settling* for boeing, and that makes my heart hurt.

People in the comments “he would have made it if he leaned before takeoff” I mean, maybe just barely but not really what I think the takeaway should be (not operating at the limit with 5 pax).

Can you configure MSFS to replicate the behavior and does it simulate it accurately enough? idk if this is still the case but older versions of MSFS tended to just use the book numbers while xplane attempted to simulate degredation of performance with age. iirc austin (xplane dev) went on a mini rant on his blog about how flight school cessnas are old and tired and it isn't appropriate to sim a 172 as if it just rolled off the line because of this

Saukkis posted:This probably an issue one would need to experience to really understand. Can you configure MSFS to replicate the behavior and does it simulate it accurately enough? You can configure the simulator with the key factors (taking off with a tailwind, maximum weight, hot and high) and you'll find that it's harder to take off and climb than in a better situation, sure. It's not accurate enough to simulate exactly what would happen to a real plane in those conditions though. The simulator is notably bad about engine performance factors and aircraft handling in ground effect, both of which were factors in this incident. This is the right take imo: Platystemon posted:I’m filing this as a corollary of “only break one law at a time”. As soon as I saw that he had six people on his six-seat plane I had alarm bells going off. Small planes cannot fly with every seat filled, a load of baggage, and full fuel tanks. The aircraft will be drastically overweight. Filling the rearmost seats also pushes your center of gravity backwards, which is potentially lethal. So even if he was technically within the POH limits, he's already chewed significantly into his safety margin. Combine that with marginal takeoff performance due to weather at the departure airfield, and a couple of pilot errors (departing with a tailwind, lifting off too soon), and the swiss cheese lines up. e: At the end they say "the pilot could not seem to replicate performance numbers found in the POH." One lesson they hammer into your head in flight school, or should, is that those numbers are the absolute best-case scenario. They are determined using a brand new airplane straight out of the factory, with a professional test pilot at the controls, and they're the best figures achieved after hundreds of tests. An amateur pilot flying a tired old plane in the real world absolutely cannot expect to hit those same numbers every time, or maybe ever. Adding a 50% margin or more -- so if your calculations say you need 3000 feet to take off, plan for 4500 feet -- is totally reasonable.

Is this a case where he might have been okay if he'd just kept it rolling on the run way for longer you build speed before taking off? Or would that just have delayed the failure?

The book said that he needed basically every inch of that 5862 ft runway. The airport conditions being literally off the chart should have been a warning flag.  If the wind speed at takeoff was close to the post‐accident winds snapshot (we know the direction is close because the windsock is visible in the takeoff video) taking off to the north would have made a net difference of approximately one thousand feet in runway saved.

Might have been OK if he'd kept rolling then just accepted the crappy climb performance instead of porpoising. Also (possibly) trying to gently lean the engine for (slightly) more power. If that had succeeded, calling NASA and saying "i was below 1000ft over a populated area for a LONG TIME due to engine issues; won't do that again."

Is there a good tool for comparing flights for almost 1 year out? Google flights (my go to) seems to max out at 11 months for what I'm checking on.

hobbesmaster posted:All that capital is stuff that can be mortgaged or sold off for more stock buybacks. They’re proposing that Boeing just licenses their name to Spirit for the entire assembly of aircraft instead of just most of it. Mortgaging the assets for stock buybacks just alters your capital structure away from equity and toward debt; it doesn't have much meaning in the real world. They might do it, but if they do it would be for tax reasons, and probably already have done so. Licensing the name to Spirit if Spirit is operating the same facilities with the same employees is sort of a distinction without a difference as well. GE's trajectory is taking a weird inefficient conglomerate and splitting it up into more sensible focused entities. All the same stuff gets made in the same buildings by the same people it's just a less clunky ownership structure. Cactus Ghost posted:the idea that antitrust regulators exist in the us is wildly unrealistic That is not correct. Antitrust regulators in the US differ from those Europe in that ours care a lot less about vertical integration. And since Boeing operates in Europe, and Airbus is based in Europe, even if US antitrust regulators were toothless (which they very much are not) that wouldn't matter.

Watch it be a net gain for aviation safety because it causes a bunch of idiots to immolate in dynamic rollover before they can take up a passenger or hit another aircraft or house.

Bad Munki posted:PROTIP: if you own a helicopter over a year without crashing at least once, you aren't flying it enough. Crashes are a natural part of flying helicopters, just like tweaking your back is part of weightlifting and negligent discharges are part of handling weapons. I crash several times a year because I actually FLY and know how to USE my helicopter. It makes me a better helicopter pilot and navigator, and it's a small part of the price you pay in the sheepdog lifestyle. Simple fact is, the "safety mentality" will build mental blocks in your head that will get you killed. You need to be comfortable putting your hand on the collective and pointing the helicopter wherever you want no matter the time, place, or status of the aircraft. Taking time to check whether the helicopter is air worthy whenever you fly one will serve to make you hesitate in an autorotation scenario. You loving safety idiots are going to get people killed all because of this loving "crash" shaming. Helicopters are inherently dangerous, you need to accept it.

If you don’t hit a pedestrian or two every year are you really a good driver? I’d say no because you aren’t really driving your car at it’s best.
