    In the Citation III

    Confessions of a New Corporate Pilot

    Life would be sweet, I thought, now that I’d successfully passed my Cessna Citation III (CE-650) type rating check ride (this was a few years back). It meant I’d be flying my first swept-wing jet. Surprisingly, my first day at the new job at Chicago Executive Airport (PWK) would also be the first time I’d been up close to a real Citation III since all the training and even my check ride happened in FlightSafety’s full-motion simulator.

    From my research, though, I knew the 650’s cabin was roomy enough for eight, and its rocket-like performance was nothing short of spectacular with a VMO (maximum operating Mach) of Mach 0.85 and 39,000 feet on a standard day. In its day, M.83 was pretty fast. That meant we could make the West Coast out of PWK with four people in the back. I learned quickly, too, that the 650’s awesome performance meant I needed to stay much farther ahead of the airplane than I’d had to in the much slower Citation II (CE-550) I’d been flying in a 12-pilot charter department.

    A privately held corporation owned this Citation III and I was the junior of three pilots. The chief pilot, my new boss, brought experience from several other flight departments, while the other pilot, I’ll call him Tom well, I was never really too sure where Tom had come from because the guy kept to himself as much as possible and wasn’t the chatty type. That made three-hour flights long when the entire conversation at FL390 ended with an occasional shrug of the shoulders.

    But who cared what one guy acted like, I thought. I was there to learn how to fit into a flight department that needed another pilot on their team. Just like in charter flying, my job was to keep the people in the back happy. I came to know these passengers much better than we ever did in the charter world. These folks sometimes invited the flight crew to their home on Nantucket when we overnighted there.

    The Interview

    Looking back on this job now though, I guess the 10-minute interview the chief pilot and I engaged in before he offered me the job should have been a tip-off that maybe something was a little odd. But with a four-year-old daughter growing up at home, the chance to dump my charter department pager that always seemed to ring at 2 a.m. beckoned hypnotically.

    Cessna Citation CE-650

    Corporate line training began right away with me flying in all kinds of weather, where I regularly rotated flying left seat with the chief pilot and Tom. Having flown left seat on the Citation II, I wasn’t brand new to jets, just speedy ones.

    After a few months, however, I began to notice a few operational oddities that started making me a little uncomfortable. Some sketchy flight planning and questions I asked were sometimes answered with annoyed expressions. If I appeared not to agree, someone might ask if I’d finished all the Jepp revisions (In those days there were no electronic subscriptions. Updates were handled by hand). I found the best solution for getting along seemed to be to just shut up and fly the airplane. Ignoring those distractions did help me pay closer attention to the little things that made my flying the jet smoother.

    Then again … On one flight back from Cincinnati (CVG), I was flying left-seat with the chief pilot in the right. I wanted to add fuel before we left since the Chicago weather was questionable, but the boss overruled me explaining, “We’re fat on fuel.”I didn’t say anything. As we approached PWK, the ATIS reported the weather had worsened, considerably. The Swiss cheese holes began to align when Chicago Approach dumped us early. We ended up burning more fuel than planned. I flew the ILS right down to minimums, but my scan uncomfortably included the fuel gauges every few seconds. After a safe landing, we taxied in with 700 pounds of Jet-A, not much for an airplane that burns 1,800 pounds an hour down low. What if we’d missed at Chicago Executive Airport and needed to run for Chicago’s O’Hare International Airport I wondered? We’d have arrived on fumes. The boss looked at me after we shut down. “Don’t tell me that whole thing bothered you. It all turned out fine, didn’t it?” (more…)

  • Remembering Gordon Baxter: Bax Seat was a Flying Magazine Reader Favorite

    by

    (Reposted by request)

    Each time I stand near my desk, my eyes naturally focus on the framed cover of the August 1983 Flying magazine. Below it is page 100, the “I Learned About Flying from That” (ILAFFT), where my first column appeared. On it, the author of Bax Seat, scrawled in brown ink, “To my friend Rob Mark. His story, my push. Gordon Baxter, August 5, 1983.”

    Many months before, Gordon Baxter had given me the Flying editor’s phone number. When I rang with my brief pitch, all I heard was “yes.” I suddenly had an assignment for my first column. That 1983 issue was the first, but not the last, time my name and stories appeared in the aviation industry’s iconic magazine. That same issue also ran a pilot report about the then-new Cessna Citation III, an aircraft I later added to my list of type ratings. Looking back, there were so many aspects of my aviation career that came to life around Bax and that August 1983 issue, not the least of which was that we became friends.

    Gordon Baxter, Bax as he preferred folks call him, helped shape my career as an aviation journalist like no one before him and only a few people since. The author of 13 books, Bax’s own magazine writing career at Flying spanned 25 years. His monthly column, Bax Seat, focused on vivid descriptions of his adventures. It was known simply as “Bax Seat.” Did I mention he was also a long-time radio personality in Beaumont, Texas, another interest we shared.

    A Bit of Bax’s Background

    I first met Bax in the mid-1970s. He brought his show, his act, or whatever the heck he called his evening of storytelling, to the Stick and Rudder Flying Club at Waukegan Airport. I was a tower controller not far away at Palwaukee Airport. Having been an avid Flying reader since high school, I switched shifts with another controller so I wouldn’t miss the event. Bax captured the audience for over an hour with stories from his flying career and his columns that often alternately “em rollin’ in the aisles” with gut-wrenching laughter and an emotional Texas-guy style that also brought tears to many an eye. Another way to think of Bax’s storytelling night was like an evening of improv but all about flying and airplanes.

    Born in Port Arthur, Texas, he learned to fly after World War II following his stint as a B-17 turret gunner. Bax was no professional pilot—just a guy with a private certificate, an instrument rating, and eventually his beloved Mooney. On the back cover of one of his books, appropriately titled Bax Seat, Flying’s Stephan Wilkinson said “Bax tries to pass himself off as a pilot, but don’t believe him. He never could fly worth a damn. But Gordon feels airplanes, loves and honors them in ways that the rest of us are ashamed to admit. And he’s certainly one of the few romantics who can express what he feels so perfectly.” I couldn’t have written that myself, but I, too, felt it.

  • Making the Brazilian ATR-72 Spin

    Note: This story was corrected on August 10th at 10:23 am, thanks to the help of a sharp-eyed reader.

    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…)

  • Flight Operations in the CAR Era

    by

    [sc name=”post_comments” ][/sc]

    CAR60-1Many an aviation scribe has described what flying was like in now bygone days. Little did I suspect that the Civil Aeronautics Board was among them, or that Part 60 of the Civil Air Regulations (CAR), Air Traffic Rules, would paint such an effective word picture of what flight operations were like in the 1940s.

    The modern offspring of these Air Traffic Rules for flight operations are today enumerated online in 14 CFR Part 91, General Operating and Flight Rules. It, at my count, contains 281 boldface sections in 14 capital letter subparts, A through N, the last of which is dedicated to the Mitsubishi MU-2B special training, experience, and operating requirements. I didn’t count the seven appendixes.

    Printed on uncoated paper with the texture and weight of the durable copy paper we fed into manual typewriters in the basic news writing class at Missouri’s J-school, the Superintendent of Documents at the Government Printing Office sold the 10-page document, “Effective October 8, 1947,” for 10 cents. I found it, quarter-folded, in the back of my dad’s last logbook.

    CAR60-3It was a quick read, with 29 flight operations regs in four sections: 2 General 60.00 rules; 14 General Flight Rules (GFR, 60.1); 4 Visual Flight Rules (VFR, 60.2); and 9 Instrument Flight Rules (IFR, 60.3). I started in section 60.9, Definitions. Most of them would fit comfortably with today’s CFR 1.1. A number of them were, however, a necessary to understand yesterday’s airspace.

    60.913 said a Control Area is “airspace of defined dimensions, designated by the Administrator, extending upwards from an altitude of 700 feet above the surface, within which air traffic control is exercised.” I knew what a control zone was because airports still had them when I learned to fly in 1976. And that was it for airspace. Either you were in it, or you were not, and when you were in it, you followed the ATC instructions.

    60.905, Airspace Restrictions, is another example of how flying used to be so much simpler and more enjoyable. Part 60 defines just two types of restricted airspace. “(a) Airspace reservation. An area established by Executive order of the President of the United States or by and State of the United States.” And “(b) Danger Area. An area designated by the Administrator within which an invisible hazard to aircraft in flight exists.”

    VFR weather minimums and cruising altitudes is where Part 60 gets interesting.

    CAR60-4

    At above ground level altitudes of more than 700 feet, pilots needed 3 miles visibility in control areas and control zones, and 1 mile everywhere else. In all airspace they needed to be 500 feet vertically and 2,000 feet horizontally from clouds. The same cloud clearances apply below 700 feet in control zones, and pilots still needed 3 miles visibility. “Control areas do not extend below 700 feet above the surface. Therefore the “elsewhere’ minimums apply.” Elsewhere, below 700 feet, pilots had to remain clear of clouds and have at least 1 mile visibility.

    Cruising altitudes, in 1947, were divided not into two hemispheres, east or west, but quarters! When flying a heading of 360° to 089°, pilots flew at odd thousands of feet, 1,000, 3,000, etc. Between 090° and 179°, they flew odd thousands plus 500 feet, 1,500, 3,500, etc. Continuing around the compass, from 180° to 269° they cruised at even thousands, 2,000, 4,000, etc. And from 270° to 359° they flew at, you guessed it, even thousands plus 500 feet.

    Finally, when cruising IFR, 60305, Right-side traffic, required “aircraft operating along a civil airway” to fly to the right side of that airway’s centerline, “unless otherwise authorized by air traffic control.” The reason, I’m guessing, is for the same reason the Strategic Lateral Offset Procedure (SLOP) is always on the right-side of the trans-oceanic routes. The more things change, the more they stay the same. Scott Spangler, Editor

  • SLOP Mitigates Collision Risk Posed by GPS Navigation Paradox

    by

    [sc name=”post_comments” ][/sc]

    SLOP-FSBwikipediaAviators live and die by their acronyms, so reading one unfamiliar motivates a frenzy of catch-up research. A short news item about changes ICAO recently made to special procedures for in-flight contingencies in oceanic airspace focused on something know as SLOP. Airliners flying in oceanic airspace such as the North Atlantic follow precise prescribed tracks to maintain separation from other airplanes doing the same thing. When they have a problem that prevents them from maintaining their spot in the track, they must leave it to address the problem, and ICAO reduced the offset to 5 miles from 15 miles and prohibited turn-arounds until the afflicted jet was below Flight Level 290 or above FL 410.

    But it didn’t really explain what SLOP is, and why it is important. The OpsGroup blog introduced not only Strategic Lateral Offset Procedures but also the Navigation Paradox posed by the position accuracy GPS makes possible. With positional accuracy measured in feet, GPS guides jets through the flight management system, which flies an airplane with a level of precision no hand-flying pilot can duplicate. In other words, jets can precisely fly the oceanic airspace tracks, which increase the risk of collisions.

    An AIAA paper, A Stochastic Conflict Detection Model Revisited, applies uncertainty modeling to improve the estimation of traffic conflicts for air traffic control. The possibility of a midair collision was six-times more likely for an aircraft precisely flying the prescribed hemispherical cruising altitude than an airplane whose altitude compliance wasn’t so accurate. SLOP made its debut in 2004 to introduce this randomness to the world’s busiest non-radar airspace, the North Atlantic airways that connect North America to Europe. As a bonus, it also reduced encounters with wake turbulence from preceding aircraft on the same track.

    slop code7700Simply put, GPS accuracy makes it possible to stack jets vertically on a prescribed airway, and any deviation from their flight level increases the risk of a collision. When pilots command the FMS to fly a randomly selected SLOP, measured in tenths up to 2 nautical miles to the right of the assigned track, those aircraft are no longer precisely vertically stacked.

    Flights must always SLOP right because offsetting them left would set them up for potential head-on collisions with jets following airways in the opposite direction. And that’s what led ICAO to narrow its contingency procedures. To increase oceanic airspace capacity, the overseers of the world’s airspace reduced the lateral separation standards that in the North Atlantic sometimes were 20 nautical miles or less.

    Given this lateral proximity, airplanes making a 15-mile contingency offset would violate the safety space of an airplane on the next airway, but a 5-mile offset would preserve it. The same logic applies to the new turn-around altitudes, because a cruising jet can’t comfortably make a 180-degree course change in the new narrower confines.

  • Barnstorming Palmyra, Wisconsin

    General Aviation Thrives on Kettle Moraine Grass

    Palmyra-1Situated along the Scuppermong River in Jefferson County, Wisconsin, the Village of Palmyra is, says the welcoming sign across the street from the Palmyra Municipal Airport (88C), “The Heart of the Kettle Moraine,” a state forest carpeting more than 22,000 acres of glacial hills, kettle lakes, and prairies about 40 miles west of Milwaukee. What remained of the Great American Flying Circus, writer Richard Bach, photographer Paul Hansen, and skydiver Stu MacPherson, landed there midweek during their Nothing by Chance barnstorming adventure in 1966. The 2800-foot Runway 9/27 is still turf, but the handful of hangars Bach mentioned has grown to approximately four dozen.

    Pulling into the parking lot on a glorious autumn day at the start of October’s third weekend, a sunshine yellow Sonex was warming its AeroVee in preparation to commit aviation, following behind a Piper Cherokee. Ropes bound a lonesome Cessna 180 on flat tires to the grass just off the concrete ramp by the Palmyra Flying Club hangar. Across the way was the fuel depot for 100 LL and autogas. While the runway is lighted turf, all of the taxiways connecting it to the ramp and all of the hangars are paved with concrete or asphalt, and all as neatly tended and cared for as the grass that looked regularly barbered.

    Palmyra-10

    Walking toward the afternoon sun, it was clear which hangars most likely witnessed the arrival of the Great American Flying Circus and the ground loop, at the end of Paul Hansen’s inaugural flight in the Parks biplane that extended their stay. Several of them were built with airplane outlines, pilot engineered out of concrete blocks and sheet metal, one with a hand-winch cable pulleyed over its rounded roof to lift the door by its wedged protrusion that made room for its occupant’s nose, spinner, and prop.

    With no windows in any of the hangars, old or the dozens of modern metal square boxes, there was no telling what manner of airplanes resided in them. But the tire-tracked grass abutting their closed doors said some winged creature lived inside. More of the modern airplane houses were connected to the paved taxiways with concrete driveways, some bordered with fancy brick inlays. Rust-free propane tanks snuggled up to most of the walls in the alley between the back-to-back hangars, where the grass was as well manicured as the rest of the airport.

    What I was looking for was the cornfield the barnstormers walked across in 1966 to reach the D&M Truck Stop Café for burgers and the Barnstormer Special, Stu’s creation that whipped up strawberry sherbet and 7 Up in the malt mixer. “Stu wrote it down, and it might still be on the menu.” If it was still there, that was going to be my lunch, but first I had to find it. Wandering among the hangars looking for someone to ask, the only person I saw was one lucky soul in a Citabria, elbow resting in the open window frame, taxiing toward he runway. He waved in passing.

    Palmyra-22With only one more cluster of hangars to explore, I met Bob Massie (on the left) and Rick Jelinek, who was standing in the open door of his Piper Cherokee. The hangar belonged to Bob, Rick said, noting that Bob “comes by to check on me to make sure I’m not doing anything foolish.” Bob said he remembered the flying circus’s visit, but didn’t offer any specifics, other than he’d taken his first flying lesson at the airport in 1946, two decades before the Great American touched down on the grass.

    “Yesterday,” they said, “we had a lot of planes in for breakfast at the Edge of Town Café.” To get there, look for the path that leads to a gap in the trees on the airport property line. Walk past the truck garage to Maple Street (State Highway 59) and look to the left. “It’s been there forever, but with Covid, it’s only open from 6 to 2, so if you want to eat, you’ll have to go into town.” The people who owned the café also owned the restaurant in town, in what used to be the Main Street bowling alley. With no money in bowling, they closed that but kept the kitchen, Rick and Bob said, but the food’s good.

    Palmyra-26Finding my way past the hangars, through the trees, and beyond the truck garage, the café truly is on the edge of Palmyra, population 1781. Before they closed up, the owners left the venetian blinds almost all the way open. Inside, eight padded chrome stools faced a Formica counter. Neatly stacked coffee cups stood ready by the two-pot Bunn brewer. Four booths abutted the front wall, two on either side of the door. A small dining room adjoined at the far end with, as far as I could see, two or maybe three tables with a chair on each of their four sides.

    It was a short walk into town. Palmyra’s Main Street was three blocks long, Bach wrote, and that’s still the case. There’s no sign of the dime store, with its glass-fronted counter displaying a selection of candy, where Stu bought a roll of crepe paper to make wind drift indicators. But there were only a couple of empty storefronts. Carlin House, home to the Palmyra Historical Society, was closed, and the Kempo Goju karate school was dark. The Kettle Hill Grill, next door to the Powers Memorial Library (Est. 1927) was serving late afternoon diners. The Dida Belle Salon offers “manicures and pedicures for men, women, and children.”

    Palmyra-42

    Other storefronts, like the Hot Rod Bar & Grill, were busier. So was Squiddy’s, a bar next door to the Dog House Liquors storefront. One imagines that Squiddy’s other neighbor, the Fellowship Bible Church, would be open the following day. Confirming its rural, small-town roots, an International Harvester Case 6150 combine grumbled down Main Street past the Uglow Block, home to the T&D Grill & Lanes, and, going the opposite direction, a Model T pickup truck flying a large American flag putt-putted by, its driver yelling hello to a friend on the sidewalk by St. Mathew Lutheran Church. Overhead, heard but unseen, an airplane hummed its way home in the late afternoon light. Maybe it was the Citabria. Scott Spangler, Editor
