So, sailors did not throw a piece of "dead" wood in the water to calculate drift?

OWT???

They don't have pink or blue, no…it's called magenta and cyan


Just in case you don't know where this comes from, it's primary color theory:

https://en.wikipedia.org/wiki/CMYK_color_model

The "primary" RGB (red, green, and blue) colors are derived from the CMYK colors as shown on that page.

Use of magenta is a holdover from old color computers that could only do four bit color. Each of the four bits was encoded as one of the primary CMYK colors, and then other colors were derived from those four by dithering and halftoning. So "magenta" is a pure color, from a color theory perspective.

That really depends on the airspace in which you're flying. In many parts of the country, the most commonly heard ATC transmission is "I have an amendment to your clearance. Advise when ready to copy. "

They did throw on old line with a bunch of knots in it.

My normal routine is to first hit "Direct" to establish a course line to the destination.

Then enroute, I will select airports along or near the route, click on them, and insert them as waypoints. I no longer have tanks to switch, but when I did I would try to do so over an airport.

Or sometimes I just click on the map to make a waypoint to dogleg around terrain or MOAs/Restricted Areas or other airspace I want to avoid or to stay within gliding distance of hospitable terrain, that sort of thing.

All this now done on my 496, but followed a similar practice with the 430's in my Cirrus when VFR.

I was not aware that I was criticizing anyone. As a CFI, I was merely pointing out that the PTS still requires us to teach, and our students to learn, pilotage and ded reckoning skills that technology has made otherwise obsolete. And that, when the technology fails, we will have extra tools to fall back on.

Old Wikipedia Tale.

Wikipedia calls it "dead reckoning or dead-reckoning (also ded for deduced reckoning or DR)..." It goes on to say "There is speculation on the origin of the term, but no reliable information."

"No reliable information" kinda describes ded reckoning, doesn't it?

Not my term - just quoting the AA captain, and citing my source (his video).

I think most of us here are aware of, and respect, your qualifications. It's a question of which hat we're wearing when we post. Sometimes I'm speaking as a CFI, sometimes as a mechanic, and at times just as a fellow pilot.

Of course there's nothing wrong with that. Nobody's saying otherwise.
