Encyclopedia > Pilotage

Pilotage is the use of fixed visual references on the ground or sea to guide oneself to a destination. Pilotage is used by people guiding vessels and aircraft, by hikers and SCUBA divers. There are other, more advanced methods of navigation using tools, such as compasses, maps, nautical charts, radar and ultimately satellite navigation systems like GPS. Beautiful natural scenes are common hiking destinations Hiking is a form of walking, undertaken with the specific purpose of exploring and enjoying the scenery. ... SCUBA is an acronym for Self-Contained Underwater Breathing Apparatus. ... There are several traditions of navigation. ... This article is about the navigational instrument. ... A map of the world by Johannes Kepler A map is a simplified depiction of a space, a navigational aid which highlights relations between objects within that space. ... A nautical chart is a graphic representation of a maritime area and adjacent coastal regions. ... This long range radar antenna (approximately 40m (130ft) in diameter) rotates on a track to observe activities near the horizon. ... Satellite navigation systems use radio time signals transmitted by satellites to enable mobile receivers on the ground to determine their exact location. ... Over fifty GPS satellites such as this NAVSTAR have been launched since 1978. ...

Pilotage depends on the pilot being able to recognise the visual references in order to make use of them. The pilot must either be familiar with those visual references or be able to discover them from a map, aeronautical chart or nautical chart. Many nautical and aeronautical disasters have resulted from the pilot incorrectly identifying visual references. Natural features are particularly difficult to recognise accurately in conditions of poor visibility. A map of the world by Johannes Kepler A map is a simplified depiction of a space, a navigational aid which highlights relations between objects within that space. ... A nautical chart is a graphic representation of a maritime area and adjacent coastal regions. ...

The term pilot refers to a person who is piloting and was originally used to describe the harbour pilot, who would help steer ships in and out of harbour avoiding local coastal hazards. Today it is more commonly used to refer to anyone who controls the flight of an aircraft. A harbour pilot guides ships through the narrow, shallow and dangerous coastal waters between a harbour and the open sea. ... A harbor (or harbour) or haven is a place where ships may shelter from the weather or are stored. ...

Common types of visual reference point used for pilotage:

Pilotage is frequently combined with navigation techniques such as dead reckoning. When a pilot at a known location cannot see the next visual reference on the route to a destination, he or she can use dead reckoning to get closer to the next reference point. This is the most common form of VFR navigation. A day is any of several different units of time. ...

River and Harbour Pilotage in the UK (1676 words)
These notes are intended to help anyone with an interest in pilots and pilotage to understand the historical development in the UK and to provide some indication of how to research the field.
Prior to 1766 pilotage existed and was operated by fishermen and local seamen with special knowledge of the area.
In Bristol control of pilotage had been vested in the Corporation of Bristol and was delegated to the Society of Merchant Venturers of Bristol from 1611 onwards.
Dáil Éireann - Volume 169 - 03 July, 1958 - Ceisteanna—Questions. Oral Answers. - Dublin Pilots' Complaint. (524 words)
I considered these representations very fully, in conjunction with the detailed observations of the pilotage authority on the submission, but I was unable to find any reason which would justify me in refusing to sanction the increase in pilotage dues proposed by the pilotage authority.
It will be appreciated that the sanctioning of the increase in pilotage dues, proposed by the pilotage authority to provide the increased remuneration to pilots on which the authority had decided, does not preclude the authority from reconsidering the adequacy of the pilotage dues at any future time.
The remuneration of the pilots is a matter for the pilotage authority and I have no power whatever to force a pilotage authority into any course of action in that regard.
