World Aeronautical Charts Noaa' title='World Aeronautical Charts Noaa' />Navigator Wikipedia. A navigator is the person on board a ship or aircraft responsible for its navigation. The navigators primary responsibility is to be aware of ship or aircraft position at all times. Responsibilities include planning the journey, advising the ships captain or aircraft commander of estimated timing to destinations while en route, and ensuring hazards are avoided. The navigator is in charge of maintaining the aircraft or ships nautical charts, nautical publications, and navigational equipment, and generally has responsibility for meteorological equipment and communications. With the advent of GPS, the effort required to accurately determine ones position has decreased by orders of magnitude, so the entire field has experienced a revolutionary transition since the 1. In naval occupationseditShipborne navigators in the U. S. Navy are normally surface warfare officer qualified with the exception of naval aviators and naval flight officers assigned to ships navigator billets aboard aircraft carriers and large deck amphibious assault ships and who have been qualified at a level equal to surface warfare officers.

Coast Guard officers that are shipboard navigators are normally cutter qualified at a level analogous to the USN officers previously mentioned. Quartermasters are the navigators enlisted assistants and perform most of the technical navigation duties. Aboard ships in the Merchant Marine and Merchant Navy, the second mate is generally the senior navigator. In aviationeditNavigators are sometimes also called air navigators or flight navigators. In civil aviation this was a position on older aircraft, typically between the late 1. As sophisticated electronic air navigation aids and universal space based GPS navigation systems came online, the dedicated Navigators position was discontinued and its function was assumed by dual licensed Pilot Navigators, and still later by the aircrafts primary pilots Captain and FO, resulting in a continued downsizing in the number of aircrew positions on commercial flights. Modern electronic navigation systems made the civil aviation navigators redundant by the early 1. The Bureau of Land Management BLM administers to nearly 250 million acres of public lands, most of which are located in the western states Alaska, Arizona. A naval ships navigator is responsible for buying and maintaining its nautical charts. A nautical chart, or simply chart, is a graphic representation of a maritime. World Aeronautical Charts Noaa' title='World Aeronautical Charts Noaa' />In military aviation, navigators are still actively trained and licensed in some present day air forces, as electronic navigation aids cannot be assumed to be operational during wartime. In the worlds air forces, modern navigators are frequently tasked with weapon systems employment and co pilot type duties depending on the type, model and series of aircraft. In the U. S. Air Force, the aeronautical rating of navigator has been augmented by addition of the combat systems officer, while in the U. S. Navy and U. S. Marine Corps, those officers formerly called navigators, tactical systems officers, or naval aviation observers have been known as naval flight officers since the mid 1. USAF navigatorscombat systems officers and USNUSMC naval flight officers must be basic mission qualified in their aircraft, or fly with an instructor navigator or instructor NFO to provide the necessary training for their duties. Nautical chartseditA naval ships navigator is responsible for buying and maintaining its nautical charts. A nautical chart, or simply chart, is a graphic representation of a maritime or flight region and adjacent coastal regions. Depending on the scale of the chart, it may show depths of water and heights of land, natural features of the seabed, details of the coastline, navigational hazards, locations of natural and man made aids to navigation, information on tides and currents, local details of the Earths magnetic field, restricted flying areas, and man made structures such as harbors, buildings and bridges. Nautical charts are essential tools for marine navigation many countries require vessels, especially commercial ships, to carry them.

The nature of a waterway depicted by a chart changes regularly, and a mariner navigating on an old or uncorrected chart is courting disaster. Every producer of navigational charts also provides a system to inform mariners and aviators of changes that affect the chart. In the United States, chart corrections and notifications of new editions are provided by various governmental agencies by way of Notices to Airmen NOTAMs, Notice to Mariners, Local Notice to Mariners, Summary of Corrections, and Broadcast Notice to Mariners. Radio broadcasts give advance notice of urgent corrections. A convenient way to keep track of corrections is with a chart and publication correction record card system. Using this system, the navigator does not immediately update every chart in the portfolio when a new Notice to Mariners arrives, instead creating a card for every chart and noting the correction on this card. When the time comes to use the chart, he pulls the chart and charts card, and makes the indicated corrections on the chart. This system ensures that every chart is properly corrected prior to use. British merchant vessels receive weekly Notices to Mariners issued by the Admiralty. When corrections are received all charts are corrected in the ships folio and recorded in NP1. A Admiralty Chart Correction Log and Folio Index. This system ensures that all charts are corrected and up to date. In a deep sea vessel with a folio of over three thousand charts this can be a laborious and time consuming task for the navigator. Various and diverse methods exist for the correction of electronic navigational charts. Nautical publicationsedit. This page from a Sailing Directions assists the navigator by providing pictures and descriptions of a harbor approach. The term nautical publications is used in maritime circles to describe a set of publications, generally published by national governments, for use in safe navigation of ships, boats, and similar vessels. The nature of waterways described by any given nautical publication changes regularly, and a mariner navigating by use of an old or uncorrected publication is courting disaster. Every producer of nautical publications also provides a system to inform mariners of changes that affect the chart. In the United States, corrections and notifications of new editions are provided by various governmental agencies by way of Notice to Mariners, Local Notice to Mariners, Summary of Corrections, and Broadcast Notice to Mariners. Radio broadcasts give advance notice of urgent corrections. For ensuring that all publications are fully up to date, similar methods are employed as for nautical charts. Various and diverse methods exist for the correction of electronic nautical publications. Mission and passage planningeditThe navigator focuses on creating the ships passage plans or mission plans for USAF purposes. A mission or passage plan can be summarized as a comprehensive, step by step description of how the voyage is to proceed from berth to berth, including unberthing, departure, the en route portion of a voyage, approach, and mooringarrival at the destination. Before each voyage begins, the navigator should develop a detailed mental model of how the entire voyage will proceed. In the aviation community, this is known as chair flying. This mental model includes charting courses, and forecasting weather, tides, and currents. Navigation App for Hiking Boating i. Phone Android Windows. Dvr Viewer Software For Linux.
