Landfall
In nautical science and aviation, landfall refers to the sighting and recognition of land after a long crossing or an ocean flight.
The term comes from English (to make landfall), but is also used among German-speaking boaters and pilots . According to Brockhaus, landfall is the point on the coast that comes first into view when sailing . The term can also be found in this meaning in Mackensen's Great German Dictionary . Schult's sailing lexicon speaks of a good landfall when you reach the intended point of approach.
In the past, the course was even intentionally changed a few degrees to starboard or port (right or left) so that when you reach the coast you would not be in doubt which side you would get to the desired port. Because after the landfall, navigation was no longer dependent on measurements ( compass or dead reckoning , later also radio ), but could rely on visual navigation using nautical charts . To this day, this is a major reason why flight cards must also be carried in modern aircraft .
shipping
In seafaring , landfall is the moment when you come from the sea to see the land, to see the land. This moment is not only dependent on the visibility , but also on the eye level of the observer due to the curvature of the earth . Generally it is some time before reaching the coast. Because of the unknown shallows, the explorers followed the supposed course of the coast on the high seas and slowly approached it to explore its course.
aviation
In the plane of language (English, however designated) is landfall lt. ICAO or FAA part of the flight plan and the flight clearance (clearance). Therefore, in addition to the course, the time of the expected landfall must be reported.
