Electronic Conspicuity (or EC) is a term used to describe aircraft that can be identified by electronic means (further details below). Currently, EC is not mandated in the UK, unlike [...]

Automatic Detection Lighting Systems (or ADLS as it is more commonly known) is a system that allows the aviation obstruction lighting fitted to wind turbines, or any other obstruction, to [...]

Shadow flicker is the effect of rotating turbine blades, causing brightness levels to vary periodically at locations where they obstruct the Sun’s rays. It can only occur when specific conditions [...]
