runway
Let an agent explain runways, their design, markings and operations from ICAO and national standards, describe variants and safety issues, and distinguish runways from taxiways and other airfield areas.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain runways, their design, markings and operations from ICAO and national standards, describe variants and safety issues, and distinguish runways from taxiways and other airfield areas.
A defined rectangular area on an aerodrome prepared for the landing and take-off of aircraft, paved or unpaved, identified by a number giving its magnetic heading, marked with thresholds, centrelines and touchdown zones, and equipped with lighting and navigation aids, with variants such as displaced thresholds, tabletop runways on plateaus, proposed endless circular runways and runways at satellite airfields; runway length, width, surface and orientation are set by aircraft requirements, wind and terrain under ICAO standards.
What it is for: Landing and take-off of aircraft.
It can be explain design and markings; relay standards and classification; describe variants and safety; distinguish from other airfield areas.
Distinguishing features
Heading-based numbering
Standard markings and lighting
Declared distances
ICAO classification
What it looks like
A long paved strip with white markings, numbers at each end and lights along the edges.
Physical character
longest civil runway: about 5500 m - Qamdo Bamda
typical width: 45 m - large airports
How it is recognised
Prepared strip for take-off and landing
Paved and unpaved, displaced thresholds, tabletop runways
Taxiways connect runways to aprons; helipads serve helicopters

What the second pass must settle
- Should runway markings and declared distances be separate entries?
- How should ICAO standards be linked?
- The registry entry has merged aliases naming variants and a proposed concept; should they be split off?
