A friend recently landed a dream job as a pilot at Southwest Airlines. When an airline pilot starts on a new type, or upgrades from first officer (second in command) to captain (first in command), (s)he is required to complete a set of Initial Operating Experience (IOE) flights per 14 CFR §121.434. This is a twice-in-a-lifetime experience for Southwest pilots, at least since 1985 when Southwest last flew the Boeing 727.
As a woman, she joins an even more select group. Southwest had 413 female pilots at the end of 2022, 4% of their pilots, up from 3.6% in 2018. 10% of her training class was female.
Her first trip started at Southwest's home airport, Dallas Love Field, and consisted of five flights and 2,985 miles (4,803 km) over two days, ending at Nashville. All of these flights were on Boeing 737-700 aircraft, which isn't too surprising since they make up roughly half of Southwest's fleet.
The next trip started a week later and comprised eight flights and 6,064 miles (9,759 km) over three days, starting eastward from Phoenix and making a big loop around the country before finishing with flights to San José del Cabo and return. The last flight of the first day was on a Boeing 737-800, and both flights on the second day were on Boeing 737 MAX 8 aircraft. The rest of the trip was again on 737-700s.
(Featured Maps often go through a few revisions to come up with a map that clearly conveys the underlying data. This one started with geodesic paths but that wasn't satisfying. A variation using Bézier paths was only a little better. Yet another try with spline paths was artistic, with the red first-trip path starting to resemble the whorl of a fingerprint, but that was a little too wild even if this approach did a better job of showing what happened at Phoenix. The winning map started with a Bézier path for the first trip combined with a spline path for the second trip. Tweaks to the Bézier-path configuration and a couple of hidden points to warp the spline path so it didn't have confusing overlaps with the earlier path led to the final map. It would be nice if hacks like those hidden points weren't necessary but there's always a bit of art to creating more than the most basic maps. A big thanks to the reviewers who helped shape the best depiction of today's topic.)
