Template:STV generates an external link to an airport information page at the Transport Search website. The links are used as a reference in airport articles when a better source is not available online (such as a link to the Aeronautical Information Publication).
An optional third unnamed parameter can be used to specify the level of zoom needed on the map, from 1 for a worldwide view to 20 for the highest level of zoom (whenever possible). The default value is 15.
The optional source parameter can be used to specify the source of the data as shown on the website. If the source is DAFIF the template adds the text "(effective Oct. 2006)".
