Some hope for the old Avidyne Cirruses

by philg

After nearly 15 years of ignoring 4000 Cirrus customers with the Avidyne Entegra glass panel (primary flight display (PFD)/multi-function display (MFD)), Avidyne announced a retrofit at Oshkosh this year. For consumers with 8K TVs from Costco (7,680 x 4,320 pixels), what does two decades of progress and $25,000 (plus installation) buy? The screens go from 10-inch 800×600 (best tech of 2003ish?) to 12-inch 1024×768 (compare to Garmin G500 TXi, a 10-inch 1280×768). This is, unfortunately, not enough resolution for clearly displaying an approach plate. The new screens have a touch panel so the number of hardware soft keys around the bezel has been reduced, as has the size of the bezel.

The menu structure of the Avidynes is not nearly as deep as what Garmin inflicts on pilots and therefore the system should be more efficient to use in flight.

Unfortunately, the $25,000 price is closer to $60,000 if you have a stock -G2 Cirrus. The Garmin 430s must be replaced with Avidyne plug-compatible IFD nav/coms. The rate-based STEC autopilot must be replaced with an Avidyne autopilot (a much better unit and, with these new retrofit screens, it will have redundant AHRS feeding it, unlike when hooked up to the legacy Avidyne Entegra). Add installation and this could easily be a $75,000 project on airframes that, pre-Biden, were worth $100-150,000. An owner who can afford to throw $75,000 at a beloved older airframe can perhaps scratch up $90,000 to implement a full Garmin solution, including the Garmin GFC 500 autopilot, which offers envelope protection even when nominally turned off (the autopilot servos will fight against a pilot who is trying to stall the airplane, overspeed it, or overbank it). Garmin is clunkier, but the investment in learning the Garmin interface can be transferred to the vast number of Garmin-equipped general aviation aircraft flying.

Here’s how the new Avidyne system looked in Hangar C:

The hoped-for certification and on-sale date is “first half 2022”.

Is there any possibility of a cheaper solution? The Dynon displays, originally developed for the experimental market, are the same resolution, work with the legacy Garmin 430W nav/coms, and cost less than $5,000 each. They’re not currently certified for composite aircraft, however. Here’s one at Oshkosh:

Note that it has been configured to display a round airspeed dial, which gives the pilot a lot more information/context than the speed tape uncritically lifted from airliners.

Finally, remember that the military has abandoned the idea that the task of piloting is fundamentally a head-down stare-at-tv-screens activity. A poster inside a Luftwaffe Airbus military cargo plane:

Note that the “Primary Flight Displays” are the heads-up displays and everything else is deprecated as a “head-down display.” (See also The latest glass cockpits are obsolete? regarding what’s in a T-6 Texan II trainer.)

Best vehicle at Oshkosh: DC-3 turned motorhome

by philg

Last day of Oshkosh (EAA AirVenture)…

Even more amazing than all of the U.S. military technology, a two-year father-son project to take a DC-3 fuselage from a field in Missouri into a highway-legal motorhome (not a trailer, but a Class A motorhome with a engine!). From Round Engine Aero:

The TWA Hotel did a great job turning a Lockheed Constellation into a bar, but it isn’t legal to drive down the road.

Two aerial vehicles that are slower than a homemade motorhome…

I asked the owner of this vehicle to kneel with me for the National Anthem, but he/she/ze/they (don’t want to assume gender ID) refused.

Define irony: Private school hosts diversity, equity, and inclusion event at a country club

by philg

Garland Greene:

Define irony – a bunch of idiots dancing around on a plane to a song made famous by a band that died in a plane crash.

I would like to propose an update to this philosopher’s work. #DefineIrony: We were invited to an exclusive (and expensive) private school’s diversity, equity, and inclusion event… at a country club.

Related, from Saturday Night Live, April 9 1977…

Julian Bond: Well, this is the major problem with these studies. The measurements of I.Q. which form the basis of comparison come from tests composed by whites for whites. The tests are culturally biased; it’s not surprising that whites would score better than blacks.

Garrett Morris: Could you give us an example of what you’re talking about?

Julian Bond: Certainly. Here are some questions that have appeared on recent I.Q. tests. Number one: “You have been invited over for cocktails by the officer of your trust fund. Cocktails begin at 4:30, but you must make an appearance at a 6:00 formal dinner at the Yacht Club. What do you do about dress?
A. Wear your blue-striped seersucker suit to cocktails and change into your tuxedo in the bathroom, apologizing to your host for the inconvenience.
B. Wear your tuxedo to cocktails, apologizing to your host for wearing a dinner jacket before 6:00 PM.
C. Walk to the subway at Columbus Circle and take the “A” Train uptown.”

Grumman Goose converted to turboprop

by philg

My favorite airplane at Oshkosh so far… a Grumman Goose converted to PT6 power. The owner was gracious and let our 7-year-old get into the cockpit and cabin, but I didn’t dare ask him how much it had cost to re-engineer the beast.

In one small area of the event we saw four different sizes of Grumman seaplanes: Widgeon, Mallard, Goose, and Albatross!

And if you thought landing a seaplane was challenging…

Should the Nord Stream pipeline be considered an engineering wonder?

by philg

The seafloor pipeline from Russia to Germany has been in the news lately (see “U.S. urges Ukraine to stay quiet on Russian pipeline” (Politico): “The Biden administration is asking an unhappy Ukraine not to make waves, as it nears Russia-Germany pipeline agreement.”; I guess Joe Biden finally found a pipeline that he could love! (compare to “Keystone pipeline canceled after Biden had permit blocked” (USA Today)).

I wouldn’t have thought that a 760-mile seafloor pipeline could be done as a practical engineering matter. From Gazprom:

The outside surface of pipes has a special anti-corrosion concrete coating. The concrete coating is made of high-density iron ore, which is crushed, mixed with cement, and put on pipes. As a result, pipes are wrapped in spiral reinforcement, which is filled with concrete, and then treated with steam in special tunnels for 24 hours. The concrete coating helps meet several challenges at once. Firstly, it keeps the pipeline on the seabed, preventing it from drifting off with undercurrents. Secondly, it serves as insulation, protecting the trunkline from outside mechanical damage.

The genius of Russian engineering? Wikipedia says that it was actually the Italians who figured out how to do this:

On 19 March 2007, Nord Stream AG hired Italian company Snamprogetti, a subsidiary of Saipem, for detailed design engineering of the pipeline. A letter of intent for construction works was signed with Saipem on 17 September 2007 and the contract was concluded on 24 June 2008

Readers: Should we be awed that this is working at all? Is the best analogy the Portuguese and other early European trips around the Horn of Africa to India and China? It is tough to believe that the sea voyage was actually more efficient than the overland one, but a lot of middlemen were cut out.

(My Ukrainian friends are not fans of this Biden Administration decision, but it won’t cost Uncle Joe any votes because these non-virtuous immigrants to the U.S. already disliked Biden/Harris for their Bigger Government policies.)

Related:

  • “The Security Implications of Nord Stream 2 for Ukraine, Poland, and Germany” (Wilson Center): … repairing the current Ukrainian-Polish pipeline would cost around €6 billion. The construction of Nord Stream 2, however, would cost €10 billion. Experts believe that Nord Stream 2 is diverting gas from the preexisting Ukrainian-Polish pipeline, meaning Europeans will receive the same amount of gas, if from a different source. … completion of the pipeline would see the European continent increase its dependence on Russian gas. If tensions were to rise between Europe and Russia, Russia could turn off the pipeline, leaving millions of Europeans without gas. Second, Europe’s reliance on Russian gas would present Russia with the leverage to further meddle in the affairs of its neighbors without consequence. Third, the new pipeline would divert the flow of gas from Ukraine and Poland, leaving these two countries to face a substantial revenue loss. They would also be forced to pay higher gas prices.

Garmin autopilot protects Bell 505 helicopter pilots and passengers

by philg

Readers of this blog will have noticed that I’ve always got my panties in a twist regarding how dumb human-scale helicopters are compared to $500 DJI drones. A bit of untwisting from Garmin:

Garmin today announced that the GFC™ 600H flight control system has received Supplemental Type Certificate (STC) approval for installation on the Bell 505 helicopter, … The GFC 600H provides a number of helicopter-tailored safety features, including attitude hold with speed stability, the innovative hover assist mode, Garmin Helicopter Electronic Stability and Protection (H-ESP™), dedicated return-to-level (LVL) mode, as well as overspeed and low-speed protection, and more.

… automatic altitude leveling airspeed and low G protection.

Thanks to the innovative hover assist mode, the system can also automatically detect a hover condition and allows for flight control inputs to help maintain position over the ground. In addition, when equipped with the optional yaw axis control, the GFC 600H can hold heading in hover.

In other words, with this system installed an airplane pilot can hover a helicopter without any training!

GE: Proud to be years late

by philg

EAA AirVenture (“Oshkosh”) starts today. Given how slowly everything in aviation moves, Oshkosh is more of a social gathering than a trade show, but manufacturers do like to announce their progress here.

Earlier this month, I checked in on the General Electric “Catalyst” Advanced Turboprop engine. This competitor to Pratt’s PT6 (first flight: 1961) had been scheduled to fly in 2018 (November 2017 press release). It still hadn’t flown. I went to GE’s aviation blog to see if they offered any explanation for being years behind schedule. The top of the blog was “A Conversation With Carmen Campbell, GE’s Transgender Advocate for Europe”:

They say it’s easy to stand with the crowd but it takes courage to stand alone. This Pride Month, the GE Aviation blog celebrates Carmen Campbell, the first person to ever transition at GE’s Grand Rapids, Michigan, site and now GE’s Transgender Advocate for Europe.

Campbell, originally from the US, is an advanced lead systems engineer based in the Cheltenham, UK Power Distribution & Controls business. She is passionate about using her experiences to help cultivate a safe and supportive workplace for her transgender colleagues.

This role sits within the transgender advocacy group, which is part of GE’s Pride Alliance. We run education sessions, work with GE to develop policies around transitioning, and provide support for transgender people within the business. The role is relatively fluid and it’s important to note that we are a resource for everyone at GE, transgender or not.

One of the areas I’m most proud of is the work we have done on the GE transition toolkit, which summarizes GE policies, provides helpful suggestions (like how to develop a communications plan), goes in to site specifics like bathroom usage, and lists who to contact for further support.

There has been some progress in the last 20 years, most notably the step change in legal representation. Gender reassignment became a protected characteristic under the UK’s Equality Act 2005, for example, and it was stipulated that people should be treated in accordance with their acquired gender.

However, I do think we’ve casually been sliding backwards since then. Certain groups, individuals and media outlets have been chipping away at the trans community, trying to roll back the trans rights that we’ve fought so hard for. Indifference can also be an issue.

“Casually sliding backwards”? Maybe the LGBTQIA+ engineers at GE can slide backwards far enough to catch up to where Pratt was in 1961. Then they could put their turboprop on an airplane and fly!

#Science says masks are the best thing that ever happened to children

by philg

Parking a warm saliva-soaked mask in front of a child’s mouth all day isn’t the most obvious way to protect children from exposure to bacteria and viruses. And “Experimental Assessment of Carbon Dioxide Content in Inhaled Air With or Without Face Masks in Healthy Children” (JAMA Pediatrics, June) heretically suggested that children might be better off with an unobstructed airway.

All is right with the world once more, however. The paper has been retracted by the editors. The only question is why humanity didn’t discover the healing power of full-time mask-wearing centuries ago.

Is the best way to #StopAsianHate to stop Asians from succeeding?

by philg

“Boston Overhauls Admissions to Exclusive Exam Schools” (New York Times, July 15):

After five and a half hours of emotional discussion on Wednesday night, the Boston School Committee voted unanimously to overhaul admissions to the city’s three selective exam schools, opening the way for far greater representation of Black and Latino students.

The new admissions system will still weigh test results and grades, but, following a model pioneered in Chicago, it will also introduce ways to select applicants who come from poor and disadvantaged neighborhoods.

Under the new system, the applicant pool will be divided into eight groups based on the socioeconomic conditions of their neighborhoods. The admissions team will consider applicants within each group, admitting the top students in each tier in roughly equal numbers.

The Groupthink aspect is interesting. The high quality schools had been operating for 100+ years in a particular way. Not a single committee member thought that continuing with the proven system made sense!

What kind of high-scoring young learner is this new policy designed to exclude?

Asian American students were 29.3 percent of Boston Latin School’s enrollment in 2020, despite making up 9 percent of students in the school’s district.

On the one hand, this might seem odd. Leaders who bravely place #StopAsianHate signs on their lawns and/or bravely tweet using the #StopAsianHate tag are trying to exclude Asians from elite schools. But perhaps there is no inconsistency. Suppose that the sign-gooder believes that the reason Asians are hated is because Asians are more successful than comparatively stupid and lazy white people. In that case, it would make sense for him/her/zir/them to place obstacles in Asians’ paths so that they can’t succeed as much. If Asians can’t get into the elite schools they won’t provoke as much envy and therefore the mission of #StopAsianHate will have been accomplished.
