Proposed features/runway=displaced threshold
|Proposal status:||Proposed (under way)|
|Definition:||A way before the actual runway which can be used for takeoff, but not landing.|
|Rendered as:||Same as runways. Potentially also mimicking the arrow pattern|
Formalize the use of a dedicated tag for displaced thresholds on aerodrome infrastructure.
Displaced thresholds are a distinct and easily recognizable part of the built structures at an airport. They are an optional section of runways that can be used for take off but not landing. The US Federal Aviation Administration (FAA) defines displaced thresholds as being "on the runway" (AIM PCG D-3). See also on Wikipedia.
Displaced thresholds are often marked with a distinct centerline repeated arrow marking with the tip of the arrow pointing to the start/threshold of the runway it belongs to.
A way tagged as displaced threshold shown in JOSM on the backdrop of Bing satellite imagery at JFK airport.
Aeroways description page - To be updated in the runway section to reflect the application of this tag.
Discussion started in 2017 from the aeroway=runway discussion page
Current use as reported by taginfo:
First draft: aeroway=displaced_threshold
The initial version of this draft suggested using aeroway=displaced_threshold instead. Feedback and current usage suggested that most airline industry refer to displaced threshold as being part of the runway. See the taginfo comparison of usage of aeroway=displaced_threshold and runway=displaced_threshold
