Collision course

A Collision Course (Latin collidere, collide ', of laedere, hurt ') is in transport a chosen direction in behavior or in the navigation in the maintenance of which it (ie a collision ), a collision occurs or could occur.

A vehicle is on a collision course when on the approach of vehicles bearing the no, or only minor, changes ( so called standing bearing ), ie each of the vehicles sees the other in almost the same direction ( Seitenpeilung ).

The term is commonly used in the aviation, space and shipping. Among other vehicles, it can also lead to collisions with objects ( rocks, piers, etc.).

Shipping

In maritime navigation, the behavior of ships is set on a collision course or to avoid a collision course in the Collision Regulations. After that ships have to meet on the port side ( to put it simply: " legal relations "). In the maneuvers of the last moment is to maneuver as it is most expedient to avoid collision.

In darkness, the price of the other ships is assessed on the basis of different colored lateral position lights, or when vessels in service and over 50 m in length (see lights management) includes reference to the position of the two steamers lights to each other. - Also, radar and AIS help to detect a possible collision course and countermeasures in time. In poor visibility, radar and / or AIS are indispensable. The correct interpretation of radar signals requires a lot of experience.

Aviation

In aviation is warned by technical systems from collision courses, eg by TCAS and ACAS, Enhanced Ground Proximity Warning System ( EGPWS ) and FLARM.
