Unavoidable Small Inaccuracies: If three LOPs can be obtained, the credibility of the resulting fix will improve considerably; the ideal crossing angles in this case would be 60°. Do not, however, expect to have a single point of intersection; this is unlikely due to unavoidable small inaccuracies in observations. Expect to get a small triangle, and then use its center, gauged visually, as the fix. If the triangle is large, discard the observations and try again. Normally, more than three EOPs are not taken.
“All have different purposes,” he said. “One for drag racing, one for spirited road driving, and so on.”
But no matter how well a Garage is designed, it seems that there is one unavoidable consequence. It's never big enough.See Also Small And Sharp:Rule for Tempering Pianos small and sharp Organs.— Tune middle C to desired pitch, then tune F— fifth below—sharp of C, until between C small and sharp F, there result three beats in five seconds. Next tune A-sharp — fourth above F-sharp of the latter, until there results one beat, each second. Next tune G—fourth below middle C — flat of C, by one beat a second; then tune D — fifth above — flat to G, by three beats in five sec¬onds; A — fourth below — flat to D; E — fifth above — flat to A; B — fourth below — flat to E; F-sharp — fourth below — flat to B; C-sharp — fifth above — flat to F-sharp; G-sharp — fourth below — flat to C-sharp ; D-sharp— fifth above — flat to G-sharp, which will make D-sharp as sharp of A-sharp, as the latter is sharp of the first F tuned.
The method then of tempering the notes of yed instruments consists in arbitrarily ad-iting the enharmonic diesis, that is, the distinction there is naturally between D sharp small and sharp E flat, G sharp small and sharp A flat, by tuning these notes too sharp for one small and sharp too flat for the other of these natural tones or intervals, small and sharp by making a similar compromise between the more minute discrepancies of the diatonic scale. Thus while no interval will be exactly true, yet none will be so adjusted as to shock the ear by false intonation, but rather add a color or quality to the tonality of the instrument, which, though harmonious, would otherwise be characterless.
On The Other Hand See Small Craft:The National Weather Service (NWS) issues advisories and warn¬ings for specific weather threats.
Small Craft Advisories are issued when winds are expected to reach speeds of up to 33 knots (38 mph) and/or sea conditions are deemed dangerous for small craft in the forecast area. Small craft are defined by NWS as "small boats, yachts, tugs, barges with lit¬tle freeboard, or other low-powered craft."
Gale Warnings are issued when winds are forecast to be between 34 and 47 knots (39 to 54 mph).
Storm Warnings are broadcast for winds greater than 48 knots (55 mph) with no upper limit on speed. A Hurricane Warning is issued only for hurricanes, with winds of 64 knots (75 mph) or more. A Hurricane Watch may be issued as an early alert to the possible arrival of a hurricane in the watch area. The watch will be changed to a Hurricane Warning when the storm is with¬in 24 to 36 hours of arrival in the specified watch area.
The Boat owner who does not have radar can still tap the power of other ships' radar to enhance the safety of his or her vessel. This is done by installing a passive radar reflector—a simple and inex¬pensive device consisting of thin, lightweight metal sheets arranged in mutually perpendicular planes. The sheets may fold for storage, but must remain rigid with respect to each other when opened for use. This relatively small reflector (each metal surface is only about a square foot in area) provides a radar reflection almost as strong as that from a medium-size steel ship. Without a reflector, the echo from the fiberglass (or wooden) hull of a small craft is so weak as to be easily overlooked among the echoes from the waves.
With a passive reflector hoisted as high as possible, the oper¬ator of a small craft can be sure that his Boat will be detected on the radar screens of passing ships. Often Coast Guard or other res¬cue craft searching for a Boat in distress are radar-equipped; the use of a passive radar reflector greatly increases a small craft's chances of being quickly spotted. |
