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
No Comments
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.
Inside a Remote Tower Operation
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…)

Aviation Mastery or Minimum Standards . . . What’s Your M.O.?
by
No Comments
Publisher Note: I’ve known Jim Lara for some time since we work together on the NBAA Single Pilot Working Group trying to tackle the challenge of reducing the accident rate for people who fly business airplanes alone. Like me, Jim believes that our training system, used to qualify pilots to minimum standards set forth by the FAA, is flawed. I too am frustrated working with people in all aspects of our industry who believe “good enough,” is just fine. Here’s how Jim explained it.

Aviation Mastery or Minimum Standards
By Jim Lara, Gray Stone Advisors
When was the last time someone in the aviation profession asked you (or you asked yourself) “Is this good enough?” What does “good enough” really mean, anyway? In my opinion, the very question constitutes an attitude of mediocrity.
The real question for aviation professionals should be: “Is good enough ever really good enough in any business or private aviation pursuit?
So many times, we use the descriptive phrases “world-class,” “best-in-class” and “excellence.” But do we really mean it or is it simply “ear candy” because it sounds good?
In the realm of professional aviation, each of us carries a mantle of tremendous responsibility for the other souls with whom we share the airspace, our families and colleagues, our companies and employers and, of course, ourselves.
The consequences of a serious misstep in our profession can have a finality that renders the statement, “I will do better next time” meaningless.
Given those stakes, to what level of performance should we aspire? Perfection? No, by definition perfection is simply unreachable.
Defining Aviation Mastery
An industry colleague of ours, President of Mastery Flight Training Tom Turner, has described a standard that is arduous and demanding, yet achievable.
He refers to it, simply, as mastery.
One of the highlights of this concept is that it can be applied to each and every one of our roles in aviation—as maintenance technicians, flight crew members, schedulers and dispatchers, business office specialists and leaders.
Tom’s graphic (right) likens mastery to “earning your stripes.” The concept, of course, is that you move up the chain of command as you master each step. In practice, we have seen that’s not always the case.
Mastery vs. Minimums
The unfortunate reality is that aviation operational standards have been put forth as minimum standards.
As you already know, this terminology is in standard usage for everything—from FBO leases with the local Airport Authority to pilot type ratings for today’s most sophisticated business jets.
The acceptance of the “minimum standards” concept has helped perpetuate a culture of minimum performance that seeps into virtually every aspect of aviation. And when you consider the deadly consequences of a misstep, don’t you find it ironic that “minimum” and “standards” are used together in the context of
“performance” and “safety”?Let me interject a true story here: Just a few weeks ago, I was present in one of our industry’s leading Part 142 training facilities. There were about a dozen full-motion simulators booked around the clock.
The classrooms were fully outfitted with the latest interactive learning tools. And there was a top-notch resource library staffed by a pair of professional librarians, eager to help with any conceivable research request.
Over lunch, the conversation between one of my classmates and the instructor went something like this:
“I’m supposed to be here for five days, but do you think I can skip the LOFT and be out of here in four days? And, if we could double up a day, can we check all of the boxes (61.58 check) in three days? What’s the minimum that I really have to do?”
For those who’ve completed a few years of recurrent training, I’m sure that conversation sounds pretty familiar.
But when the instructor really started probing to gauge the student’s true level of understanding (systems, performance, etc.), the student got resistant and asked, “What’s the minimum that I need to know?”
Mastering Mastery
If we truly think of ourselves as aviation professionals, what level of performance comes along with earning that title? I argue that it is mastery and mastery alone.
That means having a profound understanding of all of the relevant subjects in your area of focus.
And it means understanding all of the whys—not just the hows.
And, finally, it means being able to mentor, teach and communicate your invaluable understanding and experiences to those individuals who are in the developmental years of their careers.
I believe that each of us in an aviation organization should be a leader. And it is up to each of us to set the standards of aviation mastery; first for ourselves, and then to influence the adoption of those standards throughout each of the functional areas in our respective organizations.
It’s not easy. Without a doubt, the performance bar to reach the mastery level is ever higher.
As we learn more, and perform at higher levels, the horizon of possibility and performance will always stretch out in front of us—always just a little out of reach.
But as we learn more, we understand more. And as we understand more, we become more valuable to our organizations. When that happens on a consistent basis, our business aviation organizations can create more quantifiable value for their host organizations.
When we attain that level of performance, sustainability of the business aviation function is within reach. But the quest for mastery must continue all the same.
Now, back to that opening question: “Is just “good enough’ ever really “good enough’?”
Well, one thing is for certain: “good enough” certainly isn’t mastery! And, if it isn’t mastery that we’re aiming for, can we rightfully refer to ourselves as “aviation professionals”?
After all, mastery is the cornerstone of aviation professionalism.

Technology Satisfies Cockpit Curiosity
by
No Comments
Maybe it’s a pilot thing, but I find the insides of airplanes just as interesting, and often more interesting, than their outsides. Cockpits and crew stations is where humans interface with the machine that carries them aloft, and I’m always curious to see how engineers of the era approached this connection.
Previously unexplored—or unattainable—positions, like the tail gunner’s station on the B-52D Stratofortress, amplifies the curiosity to almost intolerable levels. Before radar replaced the gunner that flew in this lonely, pressurized cubicle separate from the rest of the crew (and how did he get in and out anyway?), what did his world look like, and what could he see out those tiny windows?
Courtesy of YouTube I’ve spent way too much time searching for and watching the Cockpit 360 videos created by AeroCapture Images. Courtesy of a news release from the National Museum of the U.S. Air Force, I’ve learned that there’s a free ACI Cockpit360º app that allows museum goers to satisfy their cockpit curiosity on their smart phones, which encourages me to investigate the acquisition of one of these devices.
Until that time, however, the Air Force Museum was kind enough to post their Cockpit 360 videos to its website. And after 40 years of wondering, my B-52 tail gun curiosity is satisfied…almost. I still don’t know how the gunner reached his lonely outpost.
The National Museum of the U.S. Air Force isn’t the only institution that employs ACI Cockpit360 videos. The ACI Cockpit 360 website lists many more, but in visiting a lot of them online, few of them post their cockpit curiosity tours online. You must visit with your smart phone. The Historic Flight Foundation posts its North American B-25, P-51 Mustang, and T-6 Texan and its Grumman F8F Bearcat and F7F Tigercat cockpits online.
The Air Force news release announced the addition of 15 new aircraft to the Cockpit 360 videos in the museum’s library, which now totals 60 different aircraft. Many of them, like the B-52, with more than one video per airframe.
The most interesting video on the site show how Lyle Jansma of ACI, records the high definition images with a Canon 5D Mark II camera body. Now, if you’ll excuse me, I need to check out the P-61 Black Widow and the B-36 Peacemaker. — Scott Spangler, Editor

Congress Proposes Drastic Cut to GI Bill Flight Training
by
No Comments
If you care about the aviation industry and the veterans, whose honorable service earned them GI Bill benefits that lead to the degrees leading to careers in it, you need to be aware of HR 3016. You may wonder what the VA Provider Equity Act, which would pay podiatrists the same at other physicians who work the Veterans Administration, and establish a new VA bureaucracy, has to do with veteran flight training benefits.
A lot.
Buried in HR 3016, introduced by Brad Wenstrup (R-Ohio), is a provision that would cut veteran flight training benefits by $882 million over the next decade. Making this disservice to our vets even worse is the discrimination it represents; veterans using their Post 9/11 GI Bill benefits to earn degrees in other disciplines do not face the cuts proposed for those pursuing aviation degrees.
Specifically, HR 3016 would cap VA flight training benefits at $20,235 a year, a total of $80,940 for a four-year degree program. As anyone already in aviation probably knows, the actual costs are much higher. With their higher operating costs, rotary-wing aircraft lead the way. According to a Helicopter Association International survey, a four-year degree for an employment ready commercial helo pilot with instrument instructor rating is approximately $212,500.
To further increase the student debt of veterans pursuing an aviation career, HR 3016 proposes that the VA no longer pay for training that leads to a private pilot certificate, the first step in a professional pilot degree program. Depending on where the students are going to school, and depending on what they are flying, this prerequisite will cost them $15,000 to $20,000.
According to the Congressional Budget Office, enactment of this legislation would deny 600 veterans a year from pursing the professional pilot degree programs that would launch their aviation careers. HR 3016 is scheduled for a vote in the House of Representatives on Tuesday, February 2. If, as expected, the House approves it, the legislation then goes to the Senate. This gives us two chances to contact our elected officials and let them know what we think of this discriminatory and unfair cut to benefits our vets have honorable earned. Scott Spangler, Editor
