There are two best glide airspeeds for this scenario: lowest descent rate (typically not published) and greatest range. Simplistically, the published airspeed number will get you pretty close to the best lift/drag ratio for make/model. This should be a memory number.

As for the landing, perhaps the best advise I read was from Bob Hoover (aerobatics in a twin Aero Commander): If you’re faced with a forced landing, fly the thing as far into the crash as possible.

The key word: fly. You are not flying if you are stalling. And you only have positive control if you're flying. Or also: don't stop too abruptly.

It’s 2% or actual cost for credit cards.

Under subparagraph f)A seller or lessor shall not impose a surcharge if a customer elects to pay for goods or services by Check, cash, debit card, processing as a debit payment, or gift card.

eCheck is considered a check.

Outlaw rewards credit cards? Or make it compulsory that the true cost of a specific credit card is revealed to the merchant who has the right to absorb or pass on, in a line item, that cost to that specific consumer?

If I know I'm paying for my own rewards, I'd choose a card that keeps more money in my pocket. I'd go as low as the PITA factor of cash.

It's not clear to me what the net benefit is of a credit card over a debit card.

But for sure the confusion ensuing from allowing debit cards to be charged as credit cards should be illegal. The merchant account providers are probably the ones reaping the free money on the racket.

Credit is the POS default, for whatever reason. Not all POS are the same. e.g. US Post Office consistently knows if I am using a debit card, and it prompts for a PIN when I do. Every restaurant, bar, service does not ask for PIN, and the handful of merchants I've inquired with say their debit card fees changed by the merchant account providers are the same as credit. Scammy.

At least in Colorado it's legal for businesses regardless of the TOS contract with a merchant account supplier to pass on the transaction and processing fees of credit cards. It's not legal to pass on cost/fees for debit cards, ACH, or cash.

Ok after rereading the preliminary report, ATC gave them a vector north and clearance to a named fix. They were not off course. While on a vector clearance, terrain and obstacle clearance is ATC's responsibility.

Once the accident flight requested and received a visual approach clearance ~30 miles out, terrain and obstacle avoidance becomes pilot responsibility. It seems likely to me that whether GPS was working or not, whether RNAV 24 or ILS 24, they'd have requested a visual approach. And the pilots did not adequately account for the terrain between the flight and the airport when they initiated the descent, and descended below minimum safe IFR altitude.

Further due to this flight operating under 14 CFR 135, there's a regulatory bridge to bind the flight to the (Part 135) Certificate Holder's operation specifications (OpSpecs). Pilots cannot operate outside of OpSpecs.

It's possible the medivac company's OpSpecs require mandatory direct visual contact with terrain and obstacles - something that could not be achieved with 0% illumination due to no moon. Some OpSpecs will prohibit visual approaches at night to non-towered airports. SRR airport has no tower. I'm not familiar with this operator's OpSpecs.

The accident flight descended into hostile terrain at night and had a CFIT.

That has less to do with GPS jamming than it does accepting a visual approach from 14 miles out with an enormous mountain they couldn't see between them and the airport.

The error as I see it is abandoning the safeguards of flying a standard instrument approach procure. RNAV or ILS, the terrain clearance is backed into the procedure. They descended below minimum safe altitude.

MON adds four new SSVs: VL and VH for VORs; DL and DH for DME. There's range changes in VOR, DME, and VORTAC.

See AIM 1-1-8. NAVAID Service Volumes https://www.faa.gov/air_traffic/publications/atpubs/aim_html...

"documented network of airports" is a poorly worded reference to MON airports as distinguished from MON navaids.

Yes, but…

They are enhancing the navaids that remain. Greater range, and a documented network of airports serviced by ground based instrument approach procedures.

The shrinkage of total number of navaids concerns me from a rural support perspective but less so as a pilot. What does concern me as a pilot is even the MON navaids are having maintenance issues resulting in outages.

In general I agree with this. (Without respect to this particular crash.)

If GPS signal is sufficiently degraded or lost, TAWS is probably unavailable (highly dependent on what navigation system is on board). TAWS might have saved them. But needing TAWS implies loss of situational awareness.

This flight crashed in the mountains ~6 miles north of the ILS 24 approach course. At ~12 miles out on the approach course, the ILS course width is ~1 mile. A full needle deflection translates to 1/2 mile off the course. A flight is not established on the approach course with a full needle deflection. Course intercept with localizer or VOR is basic instrument work - GPS not required.

The flight requested ILS 24, later they indicated airport in sight, requested and received a clearance for a visual approach. That means pilots have full responsibility for terrain and obstruction clearance. The visual approach requirement is to maintain contact with with airport.

It seems to me they went off course, by a lot, for reasons I'm not clear on, and then descended prematurely into hostile terrain at night, which is likely why they lost visual contact with the airport. The terrain blocked their view and by the time they realized they were descending into hostile terrain they crashed.

If that's what happened, GPS signal loss is perhaps an instigating source of distraction and confusion but I do not see how it's a primary factor. If the signal becomes degraded, navigation should indicate it (auditory and visual) and that source is ignored entirely. Falling back to ground based navigation should be familiar, it doesn't need to be as precise as GPS, the instrument approach procedure has terrain clearance baked into it.

Best practice is to follow the instrument approach procedure to the final approach fix, then do the visual approach - especially at night which many have argued constitutes instrument flight conditions - mountains will be invisible. Pitch black on black.

Kernel oomkiller is useless for the desktop. It only cares about kernel survival. There's user space oom options, like oomd, earlyoom ... but I'm not sure any heuristic really knows what user space program to clobber.

Resource control via cgroupsv2 sounds better for both desktop and server use cases, differing by what processes receive minimum resources. But IO isolation remains elusive. Some suggest a database of hardware capabilities, I wonder if a cheap estimator of throughput and latencies could do this dynamically.

Anyway, I'm not convinced user space should care about or rely on the kernel oomkiller. Well before it even considers the situation human interactivity with the system was lost.

I wonder if Gaudi gets a cut!

I expect pilots called company, and risk assessment made the decision. Pilots can and do make flight safety decisions, but operational control is an airline decision.

I prefer the term "hugged to death" which I only ever have seen used on HN.

Republicans in Congress were elected expressly to allow Trump to do as he wishes.

>A populace with a functioning representative democracy deserves its leaders.

Yes. Despite Trump himself being a fascist, the government continues to operate as a representative democracy. Most Congresscritters have their thumbs up their asses waiting for things to get much worse, which mirrors the vast majority of voters.

Is it national apathy? Decadence? Addiction to the drama, anger and depravity of Trump TV?

Feudalism says: buy new hardware, peasant.

I don't know what "equally annoying" would be for a company and its customers, i.e. a fair compromise. But we need a law requiring companies open source their hardware within X days of end of life support.

And somehow make sure these are meaningful updates. Not feature parity with new hardware, but security parity when it can be provided by a software only update.

Otherwise a company in effect takes back the property, without compensation.

Surcharges are permitted in some states.

Colorado law recently changed permitting merchants to pass on the actual cost of processing, except for cash, check and debit payments.

https://colorado.public.law/statutes/crs_5-2-212

This law overrides any prior contractual agreements with banks/processing companies that prohibit surcharges. This is previously how MasterCard and VISA coerced merchants into absorbing the processing fee, by contractually requiring credit same as cash pricing.

They are likely getting more frequent brake pad replacements.

Not a significant cost. But they sure as shit aren't getting what they think they're getting. Meaningfully farther ahead.

I now see it all as a risk assessment rather than as ritualistic combat.

Winning local elections means having the political power and thus economic power to Deflock your town.

Telling illiberal authoritarians to go fuck themselves is reasonable. But power is still more important than insults.

The medical and financial predators targeting elderly makes me wonder how to constrain it. The law doesn’t really help, short of having a court determine there’s some level of incapacity.

In theory the law doesn’t require victim cooperation. In practice, I’ve found local prosecutors won’t touch a case with an uncooperative victim. And most victims don’t cooperate whether out of humiliation or rejection pf the very idea they can be scammed. Because to them all scams are obvious, and only morons are scammed. They consistently lack imagination for the sophistication and manipulation component of scams, thinking it’s all about obviousness.

I’m sure it’s not only a case of “save the children”. Saving grandma’s retirement accounts is also important. The internet is a cesspool.

Federal court orders (judicial branch) are enforced by federal law enforcement such as marshals, FBI, ATF, and so on (executive branch).

If the executive branch is lawless, then there’s selective enforcement. We are seeing the emergence of the dual state. Authoritarianism that follows the law sometimes so it sorta looks legitimate but sometimes isn’t at all legitimate.

Therefore the customers of these companies are contributing some of their hard earned money to help these companies grovel to a would-be dictator, and build his precious ballroom.

I'm not a big fan of the general strike idea whereby people forego income to send a message. Why not stop spending money with these companies for some period of time? I think telling these companies to go fuck themselves will put more money in everyday people's pockets than not showing up for work.

Apple consumers would be on more ethical grounds paying a tariff than what Tim Cook has committed them to. He showed up at the White House on Saturday well after the reporting that the government had murdered a law abiding citizen, while that government protected the assailants, and smeared the victims.

It's disgusting. I find him disgusting. I find all of these companies disgusting.

>Historically, the FAA had zero interest/jurisdiction in most hobbyist aircraft below 500 feet, they would not even bother entertaining such as it was not relevant to their opperations.

This is not correct. See 14 CFR 101, 103, and 105. There's a long history of the FAA concerning itself with hobbyists flying model aircraft, moored, and unmanned balloon, rockets, kites, parachutes, and ultralights. I mentioned this, you glossed over it. Their histories predate 2012.

https://www.ecfr.gov/current/title-14

>Helicopters, planes, and quadcopters could be flown freely under general guidance, with no actual enforcing regulations.

Helicopters and airplanes have been regulated under 14 CFR 91 for a very long time, and were regulated by the CAA (the Civil Aeronautical Authority, precursor to FAA), and their operations are certainly regulated below 500'. And it is definitely enforced.

If you're referring to the years long regulatory lag for drones/sUAS before the The FAA Modernization and Reform Act of 2012 which also gave us 49 USC 44809 "Exception for limited recreational operations of unmanned aircraft" - ummm, well all I can say is welcome to aviation. It's been significantly regulated the whole time, and just because some folks were not aware of this fact, doesn't mean it wasn't.

Maybe check out The Great Waldo Pepper with Robert Redford though. That begins in a genuinely unregulated era.

Yeah, the higher departure stress due to greater fuel weight at takeoff was mentioned in this video.

I'm now curious about the engineering of the displaced threshold. This is a portion of the runway that aircraft can taxi onto and use for takeoff but not for landing. I thought (assumed) that the landing was harder on the runway surface than takeoffs, hence the displaced threshold wasn't designed for that force.

The displaced threshold could also be used to ensure obstacle and terrain clearance on landing - simply disallow that portion from being used in order to create an offset from the obstacle. But I don't know whether this is a very common reason for displaced threshold usage.

-- Video also mentions https://skybrary.aero/ which I'd not heard of previously. Looks neat. I'll have to check it out.
