Definition of Clearway
The Lodz chart above shows 'CWY 60x300' which suggests that the area in question is in fact a 'Clearway' rather than a 'Stopway'. A Clearway is a 'Cleared Area free of Obstructions' - for the engine out climb segment, quite obviously not for taxying on! In the case of Lodz it has this feature at both ends of the runway - well done Lodz!
