For Socrates, the only way the ship will reach its destination – the good – is if the navigator takes charge.

If the navigator measures the direction in real life, the angle can then be drawn on a nautical chart and the navigator will be on that line on the chart.

a navigator, and a seaman, which will be a guarantee for the details of this posthumous publication.

When used this way, a navigator will from time to time measure the sun's altitude with a sextant, then compare that with a precalculated altitude based on the exact time and estimated position of the observation.

This does not seem to be something that will benefit his tribe terribly, but the navigator isn't one to stare down the barrel of a lightning gun, and sends him on his way.

However it is not unusual for a technical team or expedition group to appoint one of their number as a team leader or surface dive marshall, but the surface marshall is often more of an administrative position, who will check divers into and out of the water, and the dive team leader is more the navigator, or the person in front of the group than someone making safety decisions for other divers.

Before each voyage begins, the navigator should develop a detailed mental model of how the entire voyage will proceed.

The navigator will draw and redraw the track line until it is safe, efficient, and in line with all applicable laws and regulations.

He proposes to go himself, and he will not go without his old team, ' Team Dædalus ': Jerry O ' Neill ( Sutherland ), a skirt-chasing engineer who designs roller coasters since abandoning supersonic stealth aircraft ; former Air Force pilot-turned crop duster and stubborn risk-taker William " Hawk " Hawkins ( Jones ); and former navigator " Tank " Sullivan ( Garner ), who is now a Baptist minister.

The Portuguese navigator Pedro de Mascarenhas may have discovered the island during his voyage of 1512 – 1513, but there is little corroborative evidence for this ; cartographic analysis points to 1532 or later.

The Arab navigator, Ahmad Bin Majid, visited Bahrain in 1489 and gave a contemporary account of the country that the first Portuguese would have seen: " In Awal ( Bahrain ) there are 360 villages and fresh water can be found in a number of places.

One traditional story describes the pilot as the famous Arab navigator Ibn Majid, but other contemporaneous accounts place Majid elsewhere, and he could not have been near the vicinity at the time.

These stories have many parallels with those of Saint Brendan the navigator, Saint Maclovius of Wales, and the stories of the Irish immrama.

Faced with what amounted to a mutiny by his navigator, White appears to have backed down and acquiesced in this sudden change of plan.

The Command Module Pilot and navigator, Michael Collins, had to have back surgery and was replaced by his backup, James Lovell, reuniting Borman with his Gemini 7 crewmate.

William L. Polhemous, the navigator on Ann Pellegreno's 1967 flight which followed Earhart and Noonan's original flight path, studied navigational tables for July 2, 1937 and thought Noonan may have miscalculated the " single line approach " intended to " hit " Howland.

The Pribilofs, named after the Russian navigator, Gavriil Pribylov, were discovered in 1786 by Russian fur traders ; no Alaska Natives are known to have lived on the island prior to this point.

Since both the Sun and Moon were observed at their respective angles from the same location, the navigator would have to be located at one of the two locations where the circles cross.

The S-61s and EH-101s have a crew of six: Two pilots, a navigator, a flight engineer, a physician and a rescue swimmer.

* Night Maze-Players are taken to a large hedge maze at night and split into groups, which each have a runner and a navigator.

A navigator on watch does not always have a corrected compass available with which to give an accurate bearing.

These conjectures have been given credentials in an article by Phyllis McIntosh in the U. S. State Department's publication Washington File ( August 23, 2004 ): " It is likely that Christopher Columbus, who discovered America in 1492, charted his way across the Atlantic Ocean with the help of an Arab navigator.

Binot Paulmier, sieur de Gonneville, French navigator of the early 16th century, was widely believed in 17th and 18th century France to have been the true discoverer of the Terra Australis ( which does not refer to Australia ).

He did not have a regular navigator and Sqn Ldr Jim Warwick DFC flew with him as his navigator on this raid.

Willem Janszoon ( c. 1570 – 1630 ), Dutch navigator and colonial governor, is the first European known to have seen the coast of Australia.

The original official historian of record, Pedro de Angelis, wrote in 1839 that this was so far north of the Falklands it was " absurd " to think that an experienced navigator could have made such an error as to put himself four degrees of latitude more northerly, and in high summer.

Tungsten models use a five-way navigator pad, in the shape of a rounded rectangle, circle, or oval and have four buttons for built-in applications.

Some historians have variously described Scolvus as a Norwegian pilot, Catalan corsair, Welsh shipmaster and Polish navigator.

Captain Joynson-Wreford was to have been the navigator on the flight but unfortunately had to stand down due to the recurrence of an old war injury.

Their experiments have given birth to what could be called " browser art ", which has been expanded by the British collective I / O / D's experimental navigator WebStalker.

The U. S. Air Force issues its USAF Observer Badge, which is identical to the USAF Navigator Badge, to Air Force officers who have qualified as NASA Space Shuttle Mission Specialists, have flown an actual mission aboard the shuttle and / or the International Space Station and who are otherwise not previously aeronautically rated as an Air Force pilot or navigator.

By taking bearings to two or more broadcast stations and plotting the intersecting bearings, the navigator could locate the relative position of his ship or aircraft.

There were more aircrew training schools in Britain, but the BCATP taught and evaluated 131, 553 pilot, navigator, observer, wireless ( radio ) operator, air gunner, wireless air gunner and flight engineer recruits from around the world, plus 5, 296 graduates from Royal Air Force ( RAF ) schools.

A more regimented team may give the captain ultimate responsibility for making all decisions regarding rest schedules, rule interpretations and the like, while the navigator has full responsibility for not only tracking the team ’ s location, but determining route choice as well.

This second approach is usually the more competitive, but prone to much larger errors if the navigator misreads the directions.

" The navigator examined the document more thoroughly and requested Portusach to accompany him to visit Glass.

Older avionics required a pilot or navigator to plot the intersection of signals on a paper map to determine an aircraft's location ; modern systems calculate the position automatically and display it to the flight crew on moving map displays.

If the navigator draws two lines of position, and they intersect he must be at that position.

During that time, the ' navigator ' position in the raceboat was extremely important ( unlike in today's small, track-like circuits ), as finding small checkpoints over a hundred mile open ocean run was a difficult endeavor.

A highly-skilled and experienced navigator can determine position to an accuracy of about.

With these, the navigator pre-computed his sight and then noted the difference in observed versus predicted height of the body to determine his position.

The navigator plots his 9am position, indicated by the triangle, and, using his course and speed, estimates his position at 9: 30am and 10am.

Fixed to a dome above the cockpit was an arrangement of lights, some collimated, simulating constellations from which the navigator determined the plane's position.

If the signal from two stations arrived at the same time, the aircraft must be an equal distance from both transmitters, allowing the navigator to determine a line of position on his chart of all the positions at that distance from both stations.

By measuring the angle to two such locations, the position of the navigator can be determined.

For example, a team that stresses a democratic philosophy may limit the captain ’ s role to be the keeper of the racing passport and rules, and limit the navigator ’ s role to carrying the map and being primarily responsible for determining the team ’ s position at any given time.

Therefore, jumps may cover a much shorter distance than would actually be possible so that the navigator can stop to " look around ": take his bearings, plot his position, and plan the next jump.

One of the pair would leave the navigator / spotter position, climb out of the plane and slide along the hull on a small rail.

To find the position of a ship or aircraft by celestial navigation, the navigator measures with a sextant the apparent height of a celestial body above the horizon, and notes the time from a marine chronometer.

If three position lines can be obtained, the resulting " cocked hat ", where the 3 lines do not intersect at the same point, but create a triangle where the vessel is inside, gives the navigator an indication of the accuracy in the three separate position lines.

Clemenza Doria married twice ; her second husband was Fernão Vaz da Costa ( c. 1520 – 1567 ), son of Portuguese Chief Justice Cristóvão da Costa and a great-grandson of the legendary navigator Soeiro da Costa ; they originated the Costa Doria family which is still thriving today as one of their members, José Carlos Aleluia Costa Doria, is a representative in the Brazilian congress, and businessman João Doria Jr. or João Agripino da Costa Doria III held a cabinet-level position in the José Sarney administration in Brazil ( 1985 – 1989 ).

The navigator also used it when taking his sights when fixing the vessel's position.

The most likely motivation for Scott to add Bowers to the polar party was a realisation that he needed another experienced navigator to confirm their position at the South Pole to avoid controversy such as that surrounding the claims of Frederick Cook and Robert Peary at the North Pole.

This actually increased the accuracy of the instrument, as the navigator no longer had to position the end of the staff precisely on his cheek.
