Everything about Pilotage totally explained
Pilotage is the use of fixed visual references on the ground or sea by means of sight or radar to guide oneself to a destination, sometimes with the help of a
map or
nautical chart. People use pilotage for activities such as guiding vessels and
aircraft,
hiking and
Scuba diving. When visual references are not available, it's necessary to use an alternative method of
navigation such as
dead reckoning (typically with a
compass),
radio navigation, and
satellite navigation (such as
GPS).
Difficulties
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.
Poor
visibility may affect safe navigation by obscuring the natural features used by pilots in an area. In such situations, pilots use navigational aids such as radar and the GPS to determine position and monitor their passage.
Visual features
Common types of visual reference point used for pilotage:
During the day:
Pilotage is frequently combined with
navigation techniques such as
dead reckoning. When a pilot at a known location can't 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.
