What I learned about aircraft paint at Oshkosh

We attended an interesting talk by Craig Barnett of Scheme Designers at Oshkosh and learned more than we thought possible about aircraft paint. (See EAA Webinar version for the images.)

Other than working to develop new designs for manufacturers, why does his job exist? Why wouldn’t people just paint an old plane in the latest factory scheme? Barnett says that if there have been any changes in the airframe design people will look at it and perceive that someone is trying to tart up the old plane with lipstick.

Why paint any design at all? Why not paint the plane white and wrap it with plastic, the way that modern commercial vehicles are done? He said that AircraftWraps will do this for you but that the wraps don’t work as well on planes as they do on cars. Panels come off every year for inspection. Exhaust gets into the vinyl (the “tailpipe” of a plane is not at the tail). Sun exposure is bad, though solid vinyl stripes last longer than printed (Our 2005 Cirrus SR20 is all-white with some vinyl stripes from the factory and it still looks pretty good after a mostly-hangared 13 years.) Barnett’s choice for elaborate designs is to bring in an airbrush artist and put the design into paint. He does caution that any kind of paint scheme that involves a fade will be difficult to touch up if damaged.

Barnett recommended a dark color on the bottom of the plane (a “split base”) for a clean appearance (belly oil won’t show) and also for “more ramp presence” and 60-70 percent of his clients choose this. He is not a fan of the polished spinner: “painted spinners add length to the plane.” What if the whole aircraft is polished? Barnett was a fan of LoPresti Knot Wax as a sealant (I can’t find any source for this).

One of Barnett’s ideas was to consider adding a paint design to the top of the wing “so that you can enjoy it while flying.”

Wherever there is an aircraft owner wealthy enough to purchase a repaint there is a potential family court plaintiff and lawyer standing by. Barnett said “use the wife’s initials in the tail number” to reduce the risk of being sued for divorce. (The talk was in Wisconsin and therefore there was no limit on the profits that could have been earned via a casual sexual encounter during AirVenture. A litigator might want to set up shop at the adjacent BeerVenture, run by a landowner who has thus far rebuffed EAA’s attempts to buy him out; BeerVenture has a big sign promising “Bikini Bartenders”)

When it is smart to have a wild ugly paint scheme? He show ZS-OHK, a flight school’s plane in South Africa. They paint their Cessnas in crazy patterns and park them next to a road where customers are drawn in.

Barnett showed a lot of ugly and “not smart” designs. One bad idea is interrupting stripes to stick in a tail number. The tail number needs to be part of the design. Stripes should follow airflow. The tail has to balance the rest of the plane.

What about coming up with a design for a Cirrus? Barnett explained that the reason newer Cirruses are no longer simply white is that the factory worked with Sherwin-Williams (the “Jet Glo” folks) to develop paints of color (not “colored paints”!) that reflect sufficient light/heat to be used on a composite aircraft. But why are these schemes mostly so ugly? Barnett says that the challenge of designing a scheme for the Cirrus is that the plane is “pregnant” (let’s look to our own waistlines rather than blaming Duluth for this!). So a paint scheme has to distract the viewer’s eye from the fundamental shape of the airplane, unlike with, say, a TBM where the shape is inherently attractive.

Cirrus had brought some “Carbon Exterior” schemes to the show and we liked them better than any of the previous factory schemes. How to adapt this scheme to an older plane? Replace the “CARBON” on the tail with “NOT CARBON”?

Where to get all of this done? We heard good things about KD Aviation in Newburgh, New York, Flying Colors in Benton Harbor, Michigan (not to be confused with Flying Colours Corp., painters of Gulfstreams), and Corrigan in Hondo, Texas (they do Gulfstreams but somehow are also able to paint small planes at a reasonable cost).

Nobody could answer the question of why this labor-intensive craft of sanding down and refinishing airplanes has not migrated to Mexico. In fact, Mexican owners are flying their planes up to Texas for paint! Econ 101 would never have predicted that. Mexicans don’t come up to Colorado to find wood craftsmen to build stuff in their houses. Why can’t this skill be developed and practiced down in Mexico where labor is comparatively inexpensive?

[Based on my visits to U.S. paint shops, every person holding a sander up to a Gulfstream in a 100-degree hangar has identified as a man. So I had to refrain from asking when there would be a social justice movement to get Americans who identify as women into this career.]

My current dream: Strip off all of the factory stripes on the SR20. Buff the white paint. Apply wraps and decals that make the entire plane look like a golden retriever. By the time it reaches the 5-year point that Barnett says is the life of a vinyl-based job, the novelty will have worn off.

Boston prices 1975 to present

Boston Magazine has a sidebar on page 61 of its August 2018 issue.

A nurse in metro Boston earned $11,596 in 1975, about $54,500 in today’s dollars, adjusted via the official CPI. Today the nurse’s median earnings will be $97,136. So the nurse is way better off, right? That’s $42,635 extra.

Median annual rent in boston has supposedly gone from $675 ($3,173 in 2018 money) to $36,012. The 1975 number sounds too low, but there were a lot of slum areas of Boston back then. If we do believe the numbers, nearly all of the nurse’s advance in pay has been captured by a landlord. Professional sports can perhaps capture the rest? A grandstand seat at Fenway Park has gone from $3.75 ($17.63) to $83.

Perhaps explaining why our highways are so jammed, tolls on an example section of the Mass Pike have gone from 70 cents in 1972 ($4.53 today) to $1.20. The cost of a subway ride has gone up only slightly faster than official inflation, from 50 cents in 1975 ($2.35 today) to $2.75.

Transitioning to electric flight (lectures at Oshkosh)

I attended the EAA Innovation Forum at Oshkosh. Note the Piper Seminole, certified in 1978 with engines dating to 1955, parked in front of the adjacent “Innovation Showcase”:

Pat Anderson, a professor at Embry-Riddle, pointed out that the early jets were re-engined prop airframes. It took a few years before the wings and fuselage caught up to the new powerplant. Similarly, he thinks that electric propulsion will result in aircraft that bear little resemblance to today’s single-engine piston airplanes.

Mike Sennett, an executive at Boeing, proceeded to talk about how 800,000 new pilots will be needed to staff the 42,700 new airliners predicted for delivery over the next 20 years (the fleet will double from 2017-2037 with huge growth in Asia). Mr. Sennett noted that aviation went from being perceived as high risk in the 1920s and 1930s to being super safe now (40,000 car-related deaths per year in the U.S. versus 0 in a typical year from airliners). [One wag, noting all of the “WomenVenture” T-shirts that had been handed out to pilots identifying as female, said “Now that airline flying is risk-free they want to get women into these jobs.”] Sennett sees a lot of growth opportunity in air freight. Currently only 1 percent of freight goes by air (35 percent by value). Boeing’s big drives are autonomy, AI, and electric propulsion. Maybe those 800,000 new pilots will turn into 1 new computer program?

After the two gray-haired guys got off the stage, a bearded California hipster began speaking. Adam Warmoth, of Uber Elevate, looked to be about 25. He explained that, within 25 years (i.e., by the time he reaches “GA age”), 6 billion people will be living in cities. The result will be that transportation grinds to a halt. People will spend hours in traffic if they want to go somewhere that is not within walking distance. Uber is going to fix all of this, at least for customers that can spend about $100 per trip, with electric aircraft that can make 25-mile trips within monster cities such as Los Angeles. The goal is a 150 mph aircraft that can hold 4 paying customers. Uber is designing common reference models that manufacturers can grab and use. Their goal is to be up and running in LA by 2023(!).

Celebrating female authorship

A friend’s Facebook post:

We passed by Womrath, Bronxville’s bookshop, which still manages to stay in business despite Amazon. … I said to [the owners] that I appreciated that their window display featured mostly female authors. I had decided not to say anything, but then I figured that window dressing also deserved reinforcement. “That wasn’t intentional,” the woman proprietor responded. “We had no idea,” the man proprietor echoed.

Some things are getting better.

Is it obvious that things today are better? (Let’s assume that “more female” = “better”) I pointed out Hawthorne’s 1855 complaint:

America is now wholly given over to a damned mob of scribbling women, and I should have no chance of success while the public taste is occupied with their trash-and should be ashamed of myself if I did succeed. What is the mystery of these innumerable editions of the ‘Lamplighter,’ and other books neither better nor worse?-worse they could not be, and better they need not be, when they sell by the 100,000.

If female authors were not featured by booksellers in 1855, why would Hawthorne have complained? And if bookstores are featuring certain authors, shouldn’t we assume that they are motivated by profits to feature books most likely to sell? Therefore it is really the customers who shape what goes into the window. Who are the customers? “The Most Likely Person to Read a Book? A College-Educated Black Woman” (Atlantic) says “Women read more books than men.” I said

This reminds me of a guy who complained to my friend about the gay-themed ads that he was seeing on Web pages. My friend had to gently inform him that ads were based on his browsing history…

Should we be patting ourselves on the back for being more enlightened than Americans of the dusty past? The Wikipedia page regarding The House of Mirth (1905):

Charles Scribner wrote [Edith] Wharton in November 1905 that the novel was showing “the most rapid sale of any book ever published by Scribner.”

A 1936 nytimes review of Gone with the Wind did not think the female gender ID of the author was worth highlighting. The book sold 30 million copies and won the Pulitzer Prize.

All of the Facebook authors’ commenting friends, most of whom are American humanities professors, agreed with the proposition that the featuring by a book merchant of female authors was an exciting new development. None expressed skepticism or asked for data.

Readers: What’s your theory about why these folks would be so interested in (a) devaluing the commercial achievements of female authors in the old days, (b) believing that commercial interest in the works of female authors is currently on the increase?

New York restrictions on Uber will increase inequality?

“New York City Caps Uber and Lyft Vehicles in a Crackdown” (nytimes):

New York became the first major American city on Wednesday to halt new vehicle licenses for ride-hail services, dealing a significant setback to Uber in its largest market in the United States.

The legislation passed overwhelmingly by the City Council will cap the number of for-hire vehicles for a year while the city studies the booming industry. The bills also allow New York to set a minimum pay rate for drivers.

This is being sold as a way to reduce inequality:

“More than 100,000 workers and their families will see an immediate benefit from this legislation,” Mr. de Blasio said, referring to the city’s army of for-hire drivers.

I wonder if the effect will actually be to increase inequality. There might be a small increase in income for Uber drivers. Presumably Uber itself will capture most of any increase, in the same way that taxi medallion owners capture all of the value of any taxi fare increase, with the drivers continuing to earn a (low) market-clearing wage. But if prices to consumers go up, the result will be kicking middle-class New Yorkers back to walking, waiting for the bus, being jammed into subway cars.

If, as promised, street congestion is reduced that will increase the mobility of a New Yorker wealthy enough to purchase a Bentley and hire a chauffeur. But the mobility of the non-rich, especially those who aren’t physically fit enough to walk long distances, stand for hours each day waiting for public transit, etc. will be reduced by higher prices:

Ride-hail apps have become a crucial backup option for New Yorkers swept up in the constant delays on the city’s sputtering subway, as happened on Wednesday when signal problems again snarled train lines across a large swath of the city. Ride-hail services have also grown in neighborhoods outside Manhattan where the subway does not reach.

Readers: What do you think? Is this “help the struggling Uber driver” regulation mostly going to help Uber shareholders and help the rich in New York distinguish themselves from the proletariat?

[An interesting data point from the article:

The taxi industry has also been decimated by Uber’s rise. The price of a taxi medallion, which is required to operate a taxi in New York, has plunged from more than $1 million to less than $200,000.

Best software for driving an Epson scanner?

Folks: I have an 11×17 flatbed Epson scanner (latest version). It came with Epson Scan 3.49a software, which does not seem to have been updated for nearly a decade. This sometimes gets into confused states on Windows 10 and won’t start, won’t show a preview window, and/or crashes. Plainly Epson does not want to be in the desktop software business.

I’m an Adobe Creative Cloud subscriber. Epson does seem to keep the drivers for this scanner reasonably up to date. What’s the most sensible approach to scanning photos, artwork, etc.?

Young Girls Creeped Out By Older Scientists Constantly Trying To Lure Them Into STEM

I hate to be like a Facebook user and post a link without comment, but here’s one from the Onion: “Young Girls Creeped Out By Older Scientists Constantly Trying To Lure Them Into STEM”

the nation’s young women are being utterly creeped out by scientists twice their age constantly attempting to lure them into the study of science, technology, engineering, and math. … The poll also revealed that some scientists also seem to have a thing for young black and latino boys.

Coleman Dark Room Tent Review

Park of the magic of EAA AirVenture (“Oshkosh”) is camping out next to the light aircraft in which one flew in. We figured that we’d get some good sleep between 8 pm when the airport officially closes via NOTAM (for the event; ordinarily this is a 24-hour airport) and 7 am when it opens again. It turns out that the warbirds go on “dawn patrol” at around 6:00 am, however, and earplugs are no match for the sound of 50 T-6 and P-51 Mustangs departing from a runway that is 500′ away.

Here’s a review of the Coleman Dark Room 6-man tent that we used…

Plus: There was a thunderstorm one night with 40 mph winds and heavy rain. The high profile of the tent makes it vulnerable to the wind, but we stayed inside and braced ourselves against the corners so the tent did not collapse. Only a bit of rain came through the door seams. Exceeded expectations for a $99 Costco purchase ($155 at Amazon).

Minus: there are plastic rings at the four corners of the tent that are critical to pitching. One of these broke in half during the first pitch. They are about 1/5th as strong as they should be (my last tent was LL Bean and lasted for 15+ years). We managed to get things working (sort of) with an extra stake.

Additional minus: Coleman was not easy to reach by phone for support. After 15 minutes of hold time and a 5-minute conversation, they sent an email demanding various photos, including one of the receipt (but who keeps paper receipts from Costco when the Costco computer stores them?). I responded to this asking “Do you really need a receipt?” and they didn’t reply. So I contacted them again via chat. They actually do demand the receipt before sending out any components. So now it is time to take the entire mess and dump it at Costco because it is basically useless without the 25-cent ring that broke and that Coleman won’t replace.

Angelina Jolie, non-black single mom and child support plaintiff

In the comments to “Who will pay to see a movie about black guys being attacked in the family court system?” I responded to a reader who suggested that single parenthood was a particularly black or uniquely black phenomenon. I pointed out

Whites seem to be at least as eager as non-whites to profit from having children, regardless of their income level. Angelina Jolie had a net worth of $275 million when she became a child support plaintiff (see “Cash value of Angelina Jolie’s children: roughly $50 million tax-free“)

As it happens, Ms. Jolie is in the news today: “Angelina Jolie accuses Brad Pitt of shirking child support in new court filing” (NBC). The single-mom-by-choice previously won primary parent status (see Bravo) and now apparently is passionate about turning a profit on her time with the kids (or her time having the nannies watch the kids play on their iPads?). I have not seen anything to indicate that Ms. Jolie identifies as black.

[How would this be adjudicated in neighboring Nevada? Absent an agreement to the contrary, Jolie and Pitt would share parenting on a 50/50 basis. Legal fees regarding custody would be $1,000 instead of $10 million. Max child support profits would be $13,380 per child per year. It is tough to understand why more Hollywood starts don’t live in Vegas and take a Pilatus into Santa Monica as necessary for their work. Maybe not for the first marriage, but after being sued once in California courts they don’t learn?]

Readers: Let’s look in the mirror before we throw rocks at various subgroups of our fellow Americans!

[My full comment:

That joke is mostly on white people. They laughed when their black neighbors availed themselves of the “marry the government” option in the 1960s. Then whites blew up their own nuclear families starting in the 1970s with the no-fault divorce revolution and plenty of whites also found the “marry the government” strategy. It is still true that the percentage is higher in the black community, but the majority of Americans who were raised outside of a two-parent household are whites (highest percentage among wealthy nations; see http://www.realworlddivorce.com/InOurEconomy )

Whites seem to be at least as eager as non-whites to profit from having children, regardless of their income level. Angelina Jolie had a net worth of $275 million when she became a child support and alimony plaintiff (see http://philip.greenspun.com/blog/2016/09/21/cash-value-of-angelina-jolies-children-roughly-50-million-tax-free/ ).

The abortion sales that we learned about (see http://www.realworlddivorce.com/ChildSupportLitigationWithoutMarriage for how this works in the states that don’t have caps on child support) were by white Americans represented by white American attorneys.

So… it may be fun for white Americans to feel superior to black Americans, but if you choose single parenthood as a yardstick with “more single” as the “worse” end, white Americans are inferior to nearly every other group of humans on Planet Earth.

Why I never get invited to anything

I was recently invited to “a unique evening contributing towards uplifting women and children” and the keynote speaker works “for greater diversity in tech”. Tickets were $300 per person. Due to our resolution to stay home every evening until our youngest child turns 18, I wouldn’t have been able to go. However, I couldn’t resist a question:

If the mission is “uplifting women and children,” why invite men? If women and children need to be “uplifted” then presumably it is men who have kept them down? Why have members of an oppressive class at a meeting devoted to ending oppression?

The organizer’s response:

Because sadly those oppressors still make 20 cents more on the dollar than the women…..

(This reminded me of the guy in the documentary who said “women may be seen as ‘sex objects,’ but men are often seen as ‘success objects'”. Would it be okay if someone ran an event devoted to “uplifting men” after noting how many are destined to come up short in our polygamous society? Also okay if the organizers decided to invite selected women on the grounds that “sadly these (female) oppressors are a lot more attractive and fun to look at than most guys”?)
