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.
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…)

Are Pilots and Controllers Shooting Themselves in the Foot?
by
[sc name=”post_comments” ][/sc]
John Carr’s blog – the Main Bang – posted an interesting piece the other day. He looked at pay scales for entry level controllers and found they will actually be paid less than janitors in Santa Clara County.
But people still seem to be signing up for controller jobs.
And of course, those of us on the cockpit side have even worse horror stories since many regional airlines hire pilots at pay rates way less than controllers, more in line with what Dave Mestas Jr. makes in Santa Clara County as a security guard according to John’s list … about $20K annually.
And pilots keep signing up for those jobs too.
If people stopped taking jobs at incredibly lousy pay rates John mentions in his piece, both the FAA and the airlines would have to increase their pay rates … or shut down.
Chances of this happening though when you’re searching for a pilot or controller job are pretty slim though, aren’t they?
But then FAA always has a fall back the airlines can’t claim. They’re the government … and they’re never REALLY out of money, are they?

Thanks From Jetwhine

I’ve been really touched by how many regular readers noticed that Jetwhine just turned one.
A year ago I had dinner with a buddy in Wichita who seriously questioned why I was trying to blend a little new media talk with the rest of the aviation world about well, anything.
I believed I had a 40-year perspective on the aviation industry that no one else did. I also thought I could thought I could say it like no one else, as some of you have taken me to task on over the past 12 months.
But that comes with the territory.
A year later, I think we’ve only begun with a little “Aviation Buzz and Bold Opinion.”
Whether it’s the FAA and user fees, the need to completely rebuild the way we pay the pilots who teach others to fly, the pilot shortage or the need to educate communities about the value of their airports, Jetwhine offers you a perspective on the industry you won’t read anywhere.
And we’ve asked nothing from you … until now that is.
Some of the things we talk about at Jetwhine evolve from the tips you send us, so keep those ideas coming.
But since blogs propagate based on the their popularity, won’t you please take a minute to pass the Jetwhine.com address on to your friends if you’ve enjoyed what you read here each week.
And ask them to pass Jetwhine on to their friends too.
So now where’s the cake?
Thanks,
Rob Mark

Pilots … Want Jobs … Must Travel

There’s pilot shortage brewing. It’s began churning on the regional airline side of the industry as pilots bail out of flying little airplanes – sorry, RJs are still big to me – headed for the majors who – so far at least – have not had any trouble recruiting.
The vacuum at the regional airlines is more vast than most people realize with flight cancellations becoming commonplace.
If you’re on the lookout for your first airline job, or are ready to move up to the majors, peddle your way down to the Hyatt Regency DFW Airport on October 26th where FLTops.com is holding a job fair for both regional and major airline pilots.
The applicant must find their own way to DFW, but once they do, the fair is only 29 bucks for a regional pilot applicant and 89 for a major airline pilot.
Not sure where you fit?
It’s worth the entrance fee – and yes, even an airline ticket – just to find out because over 25 airlines will be in place at the hotel, most interviewing pilots on the spot or the next day.
This also offers you the opportunity to network with a few hundred other applicants to learn how their experience fits with what recruiters want.
