Clearway

In aviation, the term Clearway (CWY), also known as open space , describes an obstacle-free area adjacent to the runway , over which an aircraft can perform the initial climb phase immediately after take-off. Its load-bearing capacity does not have to correspond to that of a runway, which means that it can also consist of a meadow or even water surface adjacent to the runway.

The available take-off distance ( TODA ) for an aircraft is the sum of the available take-off distance ( TORA ) of the respective take-off direction and the length of the open area (CWY):

${\displaystyle \mathrm {TODA=TORA+CWY} }$

Recommendations for the design

The open area must connect to the end of the taxiing runway and must not exceed half the length of the TORA takeoff runway available. It should be at least 150 m wide and must be free of obstacles. These recommendations are made by the International Civil Aviation Organization ICAO .

meaning

The existence of such routes is also of economic importance, as they increase the maximum take-off weight of an aircraft , which affects the possible payload and refueling .
