alright this might be a complete mistake but gonna try this anyway.

Discuss anything related to infrastructure (roads, bridges, railways, waterways, trails, etc)
Try to stay on on topic, decent rule of thumb is discussion about specific vehicles of transportation are better suited to other generals (or boards) but talking about any building/structure that is relevant in transportation is fair game

In fairness, nobody in Europe had died of a heroin overdose or been shot due to legality of guns and heroin. I think...

Shit got both wrong.

What's the procedure when this happens? Does the pilot inform ATC? Is there a ground crew waiting near the runway in case there is an accident?

I was in a 737 NG (either a -700 or -800, I don’t remember) which only had slats deployed on landing. Pilots were on final, and the plane was slowing down, but it felt wrong. As soon as I thought that, the pilots selected go around thrust. We circled for about ten minutes with no change in flaps. I am sure they tried the alternate flaps on the overhead panel. We lined back up, and landed at Vref + 45 or 50. The thing about no flaps deployed is that the spoilers don’t work as lift dumps reducing braking effectiveness significantly. We touched down firmly, with spoiler deployment and maximum reverse (interesting considering another 737 pilot told me they never use it) and autobrakes set to max. It still took over 8,000 feet of runway to stop. The brakes were cooked to the point where the rotors were warped. This was after a six and a half hour flight so it wasn’t like we were heavy with fuel, but there was a full passenger load.
>>
I was on a 777 where the flaps weren't working properly after takeoff, so we flew around for the better part of an hour dumping fuel before going back to the airport (was a flight to Hong Kong). Annoyingly they wouldn't turn on the entertainment system. Felt like a much faster landing speed.

>>1313732
On the Airbus, there are 3 hydraulic systems, Green, Yellow and Blue. If a hydraulic system fails, the PTU, Power Transfer Unit (the thing which makes a "bark" noise) will keep all 3 hydraulic systems pressurised. All 3 hydraulic systems can extend the flaps and slats.

If, however, 2 hydraulic systems have lost hydraulic fluid and cannot be pressurised, then things get messy. As mentioned, various flaps and slats use one of the 3 hydraulic systems. If Green fails and the hydraulic fluid leaks out, only some flaps and slats stop working. But if both Green and Yellow fail, or Green and Blue or Yellow and Blue fail, then flap failure can occur.

In such a case, the aircraft is limited to Cat 1 landings. The pilots must then reference the QRH for what their approach speed in failure should be and they will also see what their landing distance will be.

Ultimately, the aircraft will need to use more reverse thrust, and depending on the hydraulic failure, will either have to brake more or use spoilers more. Since the Airbus has brake fans, overheating of the brakes is less of an issue.

Also, if there is a dual hydraulic failure, on flare, the aircraft will enter Direct Law. At all other points the aircraft should be able to stay in Normal Law.

Land slightly faster, slightly shallower angle. Jeez, its called a SECONDARY control for a reason. In some wind conditions, you're SUPPOSED to leave flaps up. Its a normal part of training. Some light planes don't even have flaps.

I bought a Supersix Evo frame. Can I use it for gravel/cx if I get a new fork to run a wider tire up front (35mm+) and a thin (28mm) in the rear?

>>1316436
Because I’ll have more traction at the back on flats and climbs anyway with my centre of gravity over the rear, and when I’m descending, I want the front tire to be grippy and have lots of traction since I’m fucked if the front skids out, but I can recover a slipping rear.
>weight over skinny rear on climbs = more traction at rear
>weight over front on descents: more grip needed

>What is it like to ride off-road on 28s?
Depends on terrain. Doable for the most part but focus on line and balance is critical. Nowhere near as fast as an XC hardtail, obviously, but in some aspects it's more fun to off road 28s. If it was impossible to do, there wouldn't be companies that offered light offroad/gravel 28s.
>>
>>1316452
this is mtb logic but it doesn't apply to road bikes where most of your weight is over the rear and the rear has a much higher chance of flatting or damaging the wheel

and traction on climbs is not a non-issue just because you think you can always star seated, it's still a huge deal, drive traction in general

you can even buy several matched sets of road bike tyres which have a larger rear like conti attack + force
>>
>>1315491
Most of the winners in gravel races have 28c tires
>>
Changing the fork to fit a 35c tire seems like a really retarded idea.
You can take an unpaved road from time to time even with a regular road bike on 28c. Or try the gravel kings another anon recommended.
But whether it will suck depends a lot on your weight. If you're big, you have to run rather high pressures to avoid getting pinch flats. And riding unpaved roads on 110 psi really sucks.
So just get a gravel bike and sell your Super Six, I guess.

High density areas are unsustainable in the long term, since high population density + birth control/women's education results in well below replacement fertility levels. High density areas need a constant stream of people from low density areas to exist; if those people can't be found within the country the city is in, the urban leadership will push to bring in large amounts foreigners, which of course will cause all sorts of cultural & political changes in time; many of those changes being detrimental to the native population.

That said, there various economic benefits from higher density levels, due to the greater specialization. Therefore, I think urban planning should aim for density levels that result in just at replacement level birthrates. With our current culture that ends up looking like sprawl. Honestly not the most pleasant thing to look at, but what would be the point of building grand cities, only to pass them on to other people's children?

Maybe, but in this case the science is pretty solid. Couldn't find a pic explaining the street curve radius thing, but the basic gestalt was that all streets used the exact same curve radius.

I'm guessing they used the smallest curve radius you can get around with an ox cart.

My grad school preached about how the era of the urban planner being the expert and respected adviser of the community is over. Now the planner is a facilitator of public opinion. The planner gives advice and provides a recommendation for a project/proposal/idea but then the public has the final say either directly or through elected officials.

Some members of the public have a much higher level of power to use in the political system because they know the system and have the time to pressure people. Wealthy, old, frequently white, homeowners have an undue influence on most communities. There are many attempts to engage other members of the public but some communities are very difficult to engage like renters. Renters are also frequently vilified by homeowners.

Some communities will be much more difficult to work in and as much as you might want to push for bike lanes or less parking the community you represent can say no. The planner can be an advocate for what they believe is right but a homeowner who has lived there for 30 years will likely have more say in the matter.

One hope is to move to a progressive YIMBY area where people think regionally but those are few and far between. Even when Minneapolis banned single family zoning there was great pressure against it and they lessened it from fourplexes to triplexes.

I was definitely bummed to hear the era of the planner being the expert is over because that's what attracted me to planning. I've found transportation planning to be less influenced by parochial interests

As they very well fucking should.

Urban planners are one of the most irritating classes of college liberals who never grew up. They are extremely authoritarian and dogmatic about what is essentially university pseudoscience and when they actually get the reigns of a project it ALWAYS winds up being overengineered garbage that winds up serving their egos more than the communities needs.

bikes arent really meant for fat people. the max weight is usually under 100kg at least on paper and the back tire will be flat under that load so you are basically riding on the rims.
