Cartoons, cartoons, cartoons.... John Crowther's Cartoon Odyssey

I think of it as The Fool's Journey. I've been asked who the "fool" is. It's me, but in the classical sense of the court jester. Only the fool was allowed to tell the king of his follies. All cartoons are available as prints or originals, framed or unframed, through my website or e-mail.

It Should Be Called the Evening Olds


It's always disconcerting when the news reports on a subject you have experience with and they get something wrong. It doesn't bode well for everything else they report on. I have substantial experience with aviation. The other evening a local news broadcast reported on an incident involving two airplanes on "Runway 876" at a certain airport. Fine, except that there's no runway in the world designated as 876. All runways everywhere are named according to their compass heading, so that, for instance, a runway heading of 210 degrees would be Runway 21 in one direction and Runway 3 (30 degrees) in the opposite direction. Information you probably never needed to know, except don't trust the news.

You got me wondering how they would number parallel runways. I found the answer here:
http://en.wikipedia.org/wiki/Runway

Regarding the cartoon, I've always found it odd that news promos tease with a question. "Does Obama have three noses? Find out at 11." If it's true, just say so. If not, it isn't news.

I can save everyone the trouble of following the link. They're designated L for left, R for right, as in runways 24L and 24R at Los Angeles International (LAX). In the opposite direction they're 6R and 6L respectively. In rare cases there's a C for center, but I no of nowhere with 4 parallel runways.

I recall once years ago a newscaster named Christine Lund in a "tease" for the 11 O'Clock ABC-TV News breathlessly reporting, "Note found in the pocket of Jim Jones" (the cult leader who led his flock to follow him in committing suicide by drinking Kool-Ade), "details at 11." At 11 o'clock she reported that the note was nothing but a grocery list.

That's "know" of nowhere. I'm still literate, honest.

"At large airports with more than three parallel runways (for example, at Los Angeles, Detroit Metropolitan Wayne County, Hartsfield-Jackson Atlanta, Denver, and Dallas-Fort Worth), some runway identifiers are shifted by 10 degrees to avoid the ambiguity that would result with more than three parallel runways. For example, in Los Angeles, this system results in Runways 6L, 6R, 7L, and 7R, even though all four runways are exactly parallel (approximately 69 degrees). At Dallas-Fort Worth, there are five parallel runways, named 17L, 17C, 17R, 18L, and 18R, all oriented at a heading of 175.4 degrees."

At Los Angeles the runways are designated 24L-6R, 24R-6L, 25L-7R, and 25R-7L, thus a pilot knows the heading on a straight-in approach. The only curious thing is that this heading is relative to magnetic not true north. As magnetic north, which is what the compass points to, is constantly drifting, eventually all runways will have to be renumbered. (The farther north the greater the change in deviation.)

Andrew, relative to your post, I should have said that the pilot knows the approximate heading to the runway.

Well you live and learn. Didn't know any of that but now that I do I'll be watching out that the pilot makes it onto the Right one... no... the Left one. Oh heck that's right (no no left)... we only have one runway!

John... honestly... I didn't know that. And you're right we should not trust the news... (about anything)
