you mean https://www.openstreetmap.org/way/273023376 ?
it's a good example of missing datas.
no entrance, no way between the entrance and the public network.
please, there should be an example of a target where the current schema 
are not enough, and not an example where the lack of data produce
a bad routing

right now I feel that the relation type=navaids should be called 
type=missingway
