<p>Red, right, returning, nun, even, increasing. </p>
<p>Waterline to deck is called:</p>
<p>Freeboard. </p>
<p>Fore-half of deck:</p>
<p>Forecastle. </p>
<p>Aft-half of deck:</p>
<p>Fantail. </p>
<p>Lights on port side:</p>
<p>Red. </p>
<p>Lights on starboard side:</p>
<p>Green. </p>
<p>Swept wings:</p>
<p>Reduced drag at high speeds. </p>
<p>Extended wings:</p>
<p>1) increased lift at low speeds;
| 2) decreased ground speed during landing. </p>
<p>Vertical axis:</p>
<p>Yawing. </p>
<p>Wet-bulb depression and fog:</p>
<p>When wet-bulb depression is less than 4 degrees, fog is likely. </p>
<p>Courseline</p>
<p>Line in which ship is heading. </p>
<p>Front of boat:</p>
<p>Bow. </p>
<p>Backside of boat:</p>
<p>Stern. </p>
<p>Nautical mile vs statute mile:</p>
<p>8 NM = 7 statute miles</p>
<p>Lubber's line:</p>
<p>The bow line. </p>
<p>Longitudinal axis:
| </p>
<p>Banking. </p>
<p>In front of:</p>
<p>Fore. </p>
<p>Lateral axis:</p>
<p>Pitching. </p>
<p>Waterline to deck:</p>
<p>Freeboard. </p>
<p>Behind:</p>
<p>Aft. </p>
<p>When is a plane most likely to stall?</p>
<p>1) high angle of attack;
| 2) when banking hard. </p>
<p>Father of Navy</p>
<p>John Paul Jones. </p>
<p>Camber</p>
<p>Curvature at the top of airfoil. </p>
<p>Angle of attack</p>
<p>The angle formed by the chord line and the oncoming air.</p>
<p>Dead reckoning</p>
<p>Navigation only by compass. </p>
<p>Aspect ratio</p>
<p>Ratio of <strong>wingspan</strong> vs.<strong>average wing width</strong></p>
<p>Aspect ratio formula</p>
<p>Aspect ratio = <strong>(wingspan)2</strong> / <strong>surface area</strong> =<strong>b² / s</strong></p>
<p></p>
<p><strong>b</strong> = wing span</p>
<p></p>
<p><strong>s</strong> = surface area of wing</p>
<p>High aspect ratio</p>
<p>Long & skinny wings</p>
<p>Low aspect ratio</p>
<p>Shot & stubby wings</p>
<p>Wingload</p>
<p>Ratio of <strong>wing surface area</strong> vs.<strong>aircraft weight</strong></p>
<p>Trim tabs</p>
<p>Small control surfaces on larger control surfaces.
They permit the pilot to balance control forces in steady flight, thereby relieving pressure on aircraft control and on the pilot.</p>
<p>Compass deviation</p>
<p>The error of a magnetic compass due to <strong>local magnetism</strong>.</p>
<p>Variation (in navigation)</p>
<p>The difference between <strong>true bearing</strong> and <strong>magnetic bearing</strong>.</p>

<p>E.g. Goose in Top Gun.</p>
<p>Perigree</p>
<p>When the moon or a satellite is closest to Earth.</p>
<p>Apogee</p>
<p>When the moon or a satellite is farthest from Earth.</p>

<p>Sloop</p>
<p>A single-mast sailing vessel.</p>
<p>Spring tide</p>
<p>--At, or soon after, new/full moons.
--High tides are very high, low tides are very low.</p>
