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…)

Three ways airline brands can make money from Twitter
Posted on April 22, 2009, 5:58 pm, by Shashank Nigam
A couple of weeks ago, I asked had an interesting conversation with a senior airline executive in Asia. Here’s how it went:
SN: What’s the emotional motivation (not $) for your customers to fly your airline?
Airline exec: Erm…I’m not sure.
SN: Hmm…is there someone front-line I can speak with who’d know, like the check-in staff, or flight crew?
Airline exec: Actually, the airport crew is outsourced, so we have little inputs, and it’s logistically tough to reach out to the crew.What fascinated me the most were two things. One – I was talking to a (very) senior executive who didn’t know what, beyond price, attracts his customers. And secondly, the fact that the airport crew is outsourced may be a short term gain ($$ savings) but a long term loss due to the lack of front line inputs.
Twitter to the rescue! Tweet. Tweet.
But market research need not be that difficult. Especially when tools like Twitter exist these days, which allow you to connect with anyone – inside or outside your company – to seek opinions, cheaply and in real-time. Twitter is the in-thing these days. An article in Forbes last week urged CEOs to tweet actively. Addison Schonland from IAG had an insightful podcast featuring three kings of airline twittering – Southwest, JetBlue and Alaska. And just yesterday, “Flying with Fish” blog wrote an article on the topic too. So, what’s the fuss all about?

It’s Awards Time for Aviation
by
[sc name=”post_comments” ][/sc]
Every year about this time aviation writers around the globe start getting a little goose bumpy wondering if they made the cut. Making the cut means you’ve been nominated by the World Leadership Forum for the Aerospace Journalist of the Year awards. The list includes the top five or six writers in a dozen different categories whose work during the last year has been deemed worthy of recognition. Just making it to the shortlist is an honor, a bit like the Oscars, but without the opportunity to meet Nicole Kidman or Natalie Portman.
This year, I’m very honored to have made that short list in the Business Aviation category for a story published in Business Jet Traveler earlier this year called, “Defending Your Business Jet.” I was also one of the lucky winners in 2004 for a story about aviation training safety.
The final decision on who walks away with the Oscar happens just before they open the doors to the Paris Air Show this year, so the next few weeks will keep us all biting our nails.
But to paraphrase the old joke, “Enough about me …”
I want to spend a moment and acknowledge a few of my comrades who also made it to the short list and what they submitted this year to the contest. Maybe we’ll find out a few more of these aviation journalist types either read Jetwhine or have Twitter accounts so we can stay more closely in touch.

A Little Fun with Air New Zealand
by
[sc name=”post_comments” ][/sc]
Here’s a new installment of our sporadic Fun Friday adventures. From a couple of Jetwhine readers I now share a couple of very funny videos. The first, a new piece of Air New Zealand branding in a way only the folks next to the folks down under can do it. Imagine United trying something like this.
And also, at no extra charge, Jetwhine is adding another video that comes straight from a secret aviation contact in Washington DC and brings an entirely new meaning to landing a jumbo. My apologies to Republican readers who may find this hilarious clip offensive.
Have a great weekend everyone.
And BTW, as long as I have your attention, assuming you’ve stopped laughing at this point, I’d like to take a moment and suggest you pass along the highly coveted Jetwhine URL to friends who might enjoy becoming a subscriber. We offer two options, e-mail or RSS. Thanks for your support.
