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…)

The Recent Airline Crashes in South Korea and Azerbaijan

While wandering around online the other day, I ran across Jenny Beatty’s post, which offered practical advice following the Azerbaijan Airlines E-190 and a Jeju Air Boeing 737-800 airline crashes. The guidelines are simple but are well worth remembering, especially the passenger alerts. I’ve shared that kind of aircraft exit advice with my wife, daughter, and friends for at least 30 years.Happy New Year. Fly safely.Rob__________________________________________Post by Jenny Beatty
As I said only days ago, I rarely comment on airplane crashes.
Then I caught a snippet of a CNN news show with a short segment on the Jeju Air Flight 2216 accident within 24 hours of it happening. A live reporter mentioned the black boxes and got the Flight Data Recorder part right. In his summary, however, he mentioned it and “the video recorder.”.
Perhaps he misspoke, a brain fade in the moment of a live on-the-scene report, and meant to say “Cockpit Voice Recorder.” But he led viewers to believe there might be actual cockpit videos, but I don’t think those exist.
It’s true that a few non-U.S. airlines have small video cameras mounted on the flight deck and release videos to the internet for entertainment purposes. Those reels of landings, seen from the pilots’ perspective, are fun to watch! But such cockpit video set-ups are disallowed in the U.S. and uncommon elsewhere — and are unlikely to meet the standards for data preservation in case of an accident.
The Facts
Another popular misconception is that you can listen to an accident aircraft’s Cockpit Voice Recorder tapes. The fact of the matter is, you won’t hear those tapes. What’s widely available online are recordings of pilots and air traffic controllers communicating on ATC radio frequencies, such as from LiveATC. However, the Cockpit Voice Recorder tapes, actual recordings of the pilots' sounds and conversations on the flight deck of an accident aircraft, are never supposed to be released to the public.
Rather, a written transcript of these recordings will be released eventually. Only a few select people are authorized to listen to the actual recordings: Accident investigators, the pilots themselves, and family members of people who perished in the accident. Accident investigators have told me — you do NOT want to hear these recordings. What you hear will haunt you for a long time, perhaps forever.
These misunderstandings are part of what prompted me to sit down and write.
Here’s what I say today:
– U.S. passenger airlines have had 0 (zero) passenger fatalities in the last five years, with the most recent fatalities being in 2019 (1 fatality), 2018 (1), 2009 (50), and 2006 (49).
– Passengers: During taxi, takeoff, and landing, stay alert and keep your shoes and eyeglasses on. Listen to flight attendant briefings, locate the nearest exit and an alternate, and buckle up tight. If there’s an emergency evacuation of the cabin, leave your belongings behind! And if you’re seated in an emergency exit row, ONLY open that exit for an emergency that requires everyone to get out quickly, such as a fire in the cabin. Listen to the flight attendants!
– Airline accident investigations are helped by the “black boxes,” which are actually bright orange and built to withstand impact, fire, and water. The Flight Data Recorder shows the position of flaps, gear, engine power, altitude, airspeed, and 3000 other parameters. The Cockpit Voice Recorder has separate channels to record pilot conversations and sounds on the flight deck, as well as all communications on the radio frequencies in use, including air traffic control and company. Both are running continuously to collect data.
– Accident investigators WILL find out what happened. They will make information available in a preliminary report within a week; the full investigation and final report can take a year or more. Factual information is more useful to us, especially to us pilots, than speculation.
My heart goes out to the grieving families and friends who lost loved ones.

Pilot’s Delight
by
No Comments
The trip was going to be simple, I thought. My friend Steve would give me a ride from Pal-Waukee Airport PWK (now Chicago Executive) and drop me off at a short grass strip near Rockford (RFD), some 50 miles west, where I’d grab another Cessna 150 and fly it back to PWK.
A couple of short delays later, we were finally ready to leave PWK. I could tell dusk was fast approaching, and since the grass strip had no lights, Steve was becoming uncomfortable about the trip. I knew it was probably the huge trees surrounding the strip that he didn’t like. “Tell you what,” he said. “I’ll drop you at Rockford, OK? The shop can ferry you over to the strip.” I nodded but smiled at his growing reluctance. But then he was a newly minted private pilot with 90 or so hours. I was a flight instructor with almost 1500.
The sun was nearing the horizon when Steve dropped me off at RFD. I began searching the ramp for my five-minute ride to the strip and stopped when I spotted a Tri-Pacer parked nearby. It wasn’t just any airplane, though. This one was … well, rough. I walked over and asked the pilot if he was my ride, and with a big smile, he said, “Sure. I’m Jack, by the way.” I gave the bird a quick once over, raised a skeptical eyebrow, and climbed into the right seat. “Let’s get going,” I said. I knew the approaching darkness wouldn’t be a problem if we wasted no time getting off.
Airborne again, I could see just how beautiful a midwestern sunset could be with the streaks of pink against the now graying sky. It seemed – well – almost peaceful looking. I thought of that old rhyme. “Red sky in the morning, sailors take warning. Red sky at night, sailors delight.” It could have been written for pilots, too.
My mind returned to matters of the moment as Jack announced our arrival over the strip. It was still relatively bright looking west, but looking toward the ground, I finally realized how dark it had become. “Ah, Jack. Maybe we should go back to Rockford, and I’ll get someone to drive me back to the strip,” I said. Jack casually waved his hand and assured me he was experienced with this sort of thing. I thought momentarily and decided that sometimes a pilot needs to trust someone with more experience. It seemed to make sense … sort of. Tonight, it was my turn to be the student.
The original plan had been to fly over the top of the strip until someone on the ground turned on their car’s headlights to guide us in. But as I gazed out the window, darkness spotted with an occasional streetlight was all I saw.
Jack smiled at me as he turned base for what I was beginning to believe was an imaginary runway. I smiled back weakly but said nothing. In my head, I began thinking we should call the whole thing off, but then I remembered Jack was more experienced.
Rolling out on the final, we approached closer. I could now see the lights of a car on the ground—but just one car! My eyes quickly moved to the altimeter, and I realized we were about 200 feet AGL. Another quick glance out the window revealed that the silhouettes I saw against the sky were the huge trees that surrounded the field, except now the tops were above us. With just that one set of headlights, my depth perception was nil.
With sweat pouring from my forehead I finally realized if I didn’t do something quickly, Jack and I would be tomorrow’s headlines. Instinctively, my hand grabbed for the throttle. “No,” Jack shouted as he pulled it out to idle. With full flaps, the airplane immediately stopped flying. I was convinced we were about to die.
A few seconds later I realized we weren’t dead. I looked out the window to see if the wheels were still attached. Almost immediately, I returned my gaze inside because I could barely see the wheels of the old Tri-Pacer for the darkness. We rolled to a stop at the end of the runway. Not even waiting for the prop to stop, I jumped out and gave a huge sigh of relief. Somehow we’d survived this insane journey.
That little voice – was it in my head or my gut? It tried to tell me a couple of times this flight was foolish, but I’d refused to listen.
Never again … ever was I going to allow another pilot, experienced or not, put me in a situation that my common sense told me was dangerous. As my career turned out, those situations did happen to me … more than once too.
As Jack and I were walking to the hangar at the grass strip I was still frazzled. I looked over at my companion and asked, “So how many hours have you logged Jack?” He thought for a minute. “Oh let me see. Must be 70 or 75 I think.”
I just stared at him. “How many times have you landed at this strip when it was getting dark like this?”
“This was my second,” Jack said with a big grin. “How’s I do?”

An Upwind Battle for Women Pilots
by
No Comments
In the Beginning
It was the afternoon of November 2, 1929, when a group of women pilots first gathered at Curtiss Field in Valley Stream, Long Island, New York. That meeting became the impetus for what became known as the Ninety-Nines, Inc., the International Organization of Women Pilots. The group named “Ninety-Nines” to represent the first 99 charter members. Today, the group’s membership includes almost 8,000 dedicated members from 44 countries worldwide.
In 1931, Amelia Earhart was elected as the group’s first President. Membership was immediately opened to other women as they became licensed pilots. In recent years, membership has been opened to include women with student pilot certificates. The 99s were organized long before the EAA, WAI, and other aviation organizations. Perhaps the Quiet Birdmen (QBs) are older, but we women are not allowed to know them. :-) Member benefits include the support given to women who yearn to make aviation a part of their lives.
We never stop promoting aviation for all.
The 99s Mission
Our purpose includes educating the pilot population and providing aviation outreach to the community. The 99s conduct pilot seminars to promote aviation safety. We also organize and conduct air racing and proficiency competitions to improve skills. We “air mark” the compass rose at local airports. We sponsor children’s career interest events, assist the FAA with safety presentations, and provide speakers to local community groups and schools.
One hundred seventeen women pilots assembled at that first 99s meeting to offer mutual support, promote aviation advancement, and create a central office to keep files on women in aviation. Louise Thaden was elected Secretary and worked to keep the group together as they struggled to establish themselves and grow. These early ideals still guide the organization today.
Although there are other female pilot organizations in various states and nations, virtually all women of achievement in aviation have been or are members of The Ninety-Nines. Those ranks include astronauts, military leaders, pioneering women airline pilots, honored record holders, renowned air show performers, high-time CFIs, airport managers, aviation industry CEO, and elected legislators – all united to support each other in a male-dominated profession.
Just how dominated? In the 1970s, women comprised approximately 6 % of the pilot population. By 2010, that number had only climbed to 7 %, a very small gain. More women are flying in every area of aviation and just for personal transportation. But still just a 1% increase????
For Those With a Financial Need
Support for the 99s comes in many forms. The group operates an incredible scholarship fund, the Amelia Earhart Memorial Scholarship Fund (AEMSF), that has been growing since 1940. The scholarship’s protective charter mandates cautious investments and limited disbursements.
Scholarship applicants must be 99s members and can request funding for academic, technical, and advanced flight training. Adding student pilots to our membership ranks added another form of mentoring and more scholarships. The AEMSF funds First Wings scholarships for our active members who have the financial need to complete their initial training. These scholarships have made possible new certificates for women worldwide. Scholarship payments reward and repay achievements such as initial solos, successful knowledge test completion, and other worthy milestones.
A more recent program for mentoring career pilot aspirants is the Professional Pilot Leadership Initiative (PPLI), which provides a carefully curated pathway to success for women. This successful program is conducted by volunteers and given without cost to Commercial pilots who want to make their careers “take off.”
Our member’s directory is a real listing of women who understand and approve of the organization’s premises. If a 99 needs assistance in another country, she has a “sister” to call upon. The 99s is a non-profit, charitable membership corporation holding 501(c)(3) U.S. tax status, with an International Headquarters building on Will Rogers World Airport (OKC), adjacent to their well-respected Museum of Women Pilots. They also own and operate (in partnership with a local board) the Amelia Earhart Birthplace Museum in Atchison, Kansas.
The 99s are a community of our own. Those women at Curtis Field in 1929 knew how things worked. Today, we honor their foresight and continue their commitment.
