Wilton: Got an email from Moses today. He wants you to return the rock you borrowed from him.
Dang, Wilton, I at least had Loran-A to guide me thru the skies. Our plane did carry a sextant, though. I used it once to thump the side of my HF receiver when a tuning sub-system something-or-other was stuck and wouldn't track. The thump fixed the HF. I carefully returned the sextant to its storage area. Couldn't replace the disturbed cobwebs, however. Let me bring you up to speed on the modern aircraft nav in the 1970s. Cross two Loran-A lines on a chart (paper, covered by 1/4" plexiglass, marked on by a one-mile-wide grease pencil. Took about 30 seconds to get a position, so by the time you marked where you are (were) you'd boogied a bit down the piece of paper. Throw in parallax error caused by the plexiglass and ground speed while plotting, throw in the width of the grease pencil, I always knew where I was at any given fifteen minute interval, +/- 10 miles. (Lots of ocean to search in a 10x10 mile area.) ... We started getting Loran-C receivers about the time I stopped flying nav and headed off to OCS. All joking aside, I carried my own charts. No grease pencil and no plexiglass. I nav'd on paper -- carried my own set in my helmet bag -- with a sharp pencil. Very anal-retentive and detail oriented. And that is the same characteristic that motivated my air station officers to ask me to apply (successfully) to OCS. D. On 3/22/07, wilton strickland <[EMAIL PROTECTED]> wrote:
----- B-52 navs used to say, "We measure it with calipers, mark it with a grease pencil and chop it with an ax." "Calipers" refers to trying to get very fine/precise readings in bearing and elevation of the celestial body on the sextant. "Mark with grease pencil" refers to the occasional dull pencil which could plot a line on some charts nearly a mile wide. "Chop it with an ax" refers to navigator judgment which sometimes leads him/her to put more weight/value on one celestial observation than another or to place more value on DR position (dead reckoning position obtained by plotting heading, air speed, time and wind/drift) than on the celestial info.
