Making an ATR-72 Spin
I wasn’t in Brazil on Friday afternoon, but I saw the post on Twitter or X (or whatever you call it) showing a Brazil ATR-72, Voepass Airlines flight 2283, rotating in a spin as it plunged to the ground near Sao Paulo from its 17,000-foot cruising altitude. All 61 people aboard perished in the ensuing crash and fire. A timeline from FlightRadar 24 indicates that the fall only lasted about a minute, so the aircraft was clearly out of control. Industry research shows Loss of Control in Flight (LOCI) continues to be responsible for more fatalities worldwide than any other kind of aircraft accident.
The big question is why the crew lost control of this airplane. The ADS-B data from FlightRadar 24 does offer a couple of possible clues. The ATR’s speed declined during the descent rather than increased, which means the aircraft’s wing was probably stalled. The ATR’s airfoil had exceeded its critical angle of attack and lacked sufficient lift to remain airborne. Add to this the rotation observed, and the only answer is a spin.
Can a Large Airplane Spin?
The simple answer is yes. If you induce rotation to almost any aircraft while the wing is stalled, it can spin, even an aircraft as large as the ATR-72. By the way, the largest of the ATR models, the 600, weighs nearly 51,000 pounds.
Of course, investigators will ask why the ATR’s wing was stalled. It could have been related to a failed engine or ice on the wings or tailplane. (more…)

How the FAA Let Remote Tower Technology Slip Right Through Its Fingers
by
[sc name=”post_comments” ][/sc]
In June 2023, the FAA published a 167-page document outlining the agency’s desire to replace dozens of 40-year-old airport control towers with new environmentally friendly brick-and-mortar structures. These towers are, of course, where hundreds of air traffic controllers ply their trade … ensuring the aircraft within their local airspace are safely separated from each other during landing and takeoff.
The FAA’s report was part of President Biden’s Infrastructure Investment and Jobs Act enacted on November 15, 2021. That bill set aside a whopping $25 billion spread across five years to cover the cost of replacing those aging towers. The agency said it considered a number of alternatives about how to spend that $5 billion each year, rather than on brick and mortar buildings.
One alternative addressed only briefly before rejecting it was a relatively new concept called a Remote Tower, originally created by Saab in Europe in partnership with the Virginia-based VSATSLab Inc. The European technology giant has been successfully running Remote Towers in place of the traditional buildings in Europe for almost 10 years. One of Saab’s more well-known Remote Tower sites is at London City Airport. London also plans to create a virtual backup ATC facility at London Heathrow, the busiest airport in Europe.
A remote tower and its associated technology replace the traditional 60-70 foot glass domed control tower building you might see at your local airport, but it doesn’t eliminate any human air traffic controllers or their roles in keeping aircraft separated.

In place of a normal control tower building, the airport erects a small steel tower or even an 8-inch diameter pole perhaps 20-40 feet high, similar to a radio or cell phone tower. Dozens of high-definition cameras are attached to the new Remote Tower’s structure, each aimed at an arrival or departure path, as well as various ramps around the airport.
Using HD cameras, controllers can zoom in on any given point within the camera’s range, say an aircraft on final approach. The only way to accomplish that in a control tower today is if the controller picks up a pair of binoculars. The HD cameras also offer infrared capabilities to allow for better-than-human visuals, especially during bad weather or at night.
The next step in constructing a remote tower is locating the control room where the video feeds will terminate. Instead of the round glass room perched atop a standard control tower, imagine a semi-circular room located at ground level. Inside that room, the walls are lined with 14, 55-inch high-definition video screens hung next to each other with the wider portion of the screen running top to bottom.
After connecting the video feeds, the compression technology manages to consolidate 360 degrees of viewing area into a 220-degree spread across the video screens. That creates essentially the same view of the entire airport that a controller would normally see out the windows of the tower cab without the need to move their head more than 220 degrees. Another Remote Tower benefit is that each aircraft within visual range can be tagged with that aircraft’s tail number, just as it might if the controller were looking at a radar screen. (more…)

Flying Job Scales Tilt Toward Pilots
by
[sc name=”post_comments” ][/sc]
When I wrote the second edition of Professional Pilot Career Guide a few years back, a great economy was in full swing with many more flying jobs than there were pilots to accept. If it had not been for the economy taking a nosedive in 2008, the pilot shortage would easily have become a fact, not a dream.
But of course the U.S. and much of the world economy took a huge nosedive which put thousands of pilots on the street and brought hiring to a halt. Over the past three years, many people have simply given up the dream and decided an aviation career isn’t worth the effort. For those folks I can only say “I’m sorry,” because the hiring boom is just around the corner.
I sat down with Louis Smith, President of FLTops.com, the pilot career information service during their recent job fair in Chicago.
If you’ve ever had a hankering to fly for a living, I hope you’ll give this podcast (below) a listen because Smith makes it clear that the airlines have finally realized there aren’t enough professional aviators out there to match attrition and retirements.
For those who say they can’t imagine working for the crummy wages of the regionals, I won’t pull the wool over your eyes. The wages are poor, but the incentives to convince pilots to fly are here beginning with American’s recent decision to offer a seniority number to any American Eagle pilot on the job by late next month. It won’t be the last nudge to fly either.
Remember too, it’s not the end of the world to spend a few years seasoning yourself before you try for the big time. Besides beefing up your resume, that experience might just someday save your life. (Applicants meet airline recruiters face-to-face in Chicago. Where were you?) — Rob Mark, Publisher

Celebrate a Century of Aviation Achievement
by
[sc name=”post_comments” ][/sc]
To appreciate what we have—and how far we’ve come, now is the time to celebrate the centennials of aviation’s many achievements. In the process, we might attract some new participants, which is surely aviation’s more pressing concern as it marches into its second century. It sure seems to be working for the US Navy and its nationwide naval aviation extravaganza.
Now is the time to start celebrating, because 1911 is when thing started to happen again in aviation. As the Wisconsin Aviation Hall of Fame reminded me during a program celebrating the centennial of the first flight in Green Bay, most of the time between the Wrights’ first flight and 1911 was spend in court, fighting patent lawsuits. With most of the lawsuits settled, the inaugural aviation events to celebrate will grow rapidly, so dig out your aviation history books and get to work.
About four dozen people of all ages surrounded me at the the WAHF presentation. Held in the spotless Jet Air hangar at Green Bay’s Austin Straubel International airport, I wasn’t the only one who noticed the difference between the rickety airplanes on screen and the sleek Cessna Mustang, Cirrus Turbo, and MU-2 parked in the corner. Before the program began, the aviators in the room showed others around and answered their questions.

Labor Day 2011
by
[sc name=”post_comments” ][/sc]
In our house when I was a kid, Labor Day was always a big celebration. My father retired at age 65 from life as a union plasterer, a profession few people can even define today. My grandfather on my mom’s side, John Kikulski, was one of the first presidents of the Amalgamated Meat Cutters Union in Chicago in the early 1920’s so that side of the family understood union cards, worker rallies and strikes pretty well.
I carried it all down for a portion of my life as a member of the Professional Air Traffic Controllers Organization (PATCO), National Air Traffic Controllers Association (NATCA) and the AirLine Pilots Association (ALPA). Today, having run CommAvia for 16 years, being part of those groups seems as if it happened to me in another life. But much of what I learned in those years of working for someone else still sticks pretty closely with me.
Labor Day began with an 1894 request from then President Grover Cleveland in an attempt to satisfy the demands for such an event from the unions and also — Cleveland hoped — to help end a crushing strike against the Pullman Railway Company in Chicago. He eventually sent 12,000 Army troops to Chicago to help squash the strike, which led to the death of two-dozen workers. Imagine a Democratic president in the U.S. trying something like that today should ALPA walk out at United Airlines.
Looking at the state of the economy here in the U.S. today though, makes me realize that many of the same issues labor fought for a hundred years ago may have fallen to the sidelines for awhile, but are still around if anyone chooses to notice.
In the early 1900’s, work life in the United States was tough, with people struggling to make ends meet, while the controllers of capital had the easy life. Some thought the analogy of famous CEOs stealing the food right out of the mouths of hungry workers and their families captured the sentiments pretty well, hence the robber baron label attached to the George Pullmans, John Rockefellers and the J.P. Morgans of the time.
Today, much is the same here in the states, although we must clearly acknowledge that the life of the average working stiff is not much better in other parts of the world either. Hundreds of American companies have shipped tens of thousands of jobs overseas to take advantage of cheaper labor in the past few decades, something that in a capitalist society they are perfectly free to do of course. Those cost-cutting measures have kept millions of Americans out of the labor pool as companies have stashed billions of dollars in cash in the kitty for a rainy day, unwilling to reinvest that cash here in the U.S. — as in hiring more employees.
