Frangible structures

P.R.F.V. structure whose properties allow it to maintain its structural integrity and rigidity up to a suitable maximum load, and tend to break into small fragments, without cohesion and without deforming plastically, so that it does not constitute a danger to aircraft.

ADHORNA is responsible for the engineering, manufacture and assembly of these structures at airports, such as towers and masts, lightning conductors, CVOR and DVOR navigation systems, stands, etc.
