Rotating wind turbine blades can cause brightness levels to vary periodically at locations where they obstruct the Sun’s rays. This can result in a nuisance when the shadow is cast [...]

Overview The following article presents an overview of the guidance surrounding Obstacle Limitation Surfaces (OLS) for aerodromes in the UK and worldwide. The most common surface types will be listed, [...]

What is an Instrument Flight Procedure? An Instrument Flight Procedure (IFP) is a set of instructions regarding navigation around aerodromes. There are two basic types, one using precision instruments and [...]

Wind turbine developers will be familiar with the constraints posed by wireless links, often belonging to mobile phone networks or utilities. This article presents an overview of why this infrastructure [...]

One of the technical mitigation options that is used for certain wind developments is the implementation of a Non-Automatic Initiation Zone (NAIZ). This is also sometimes called Non-Auto Initiation Area [...]

Background The noise pollution produced by a wind farm can become a problem for local communities, developers and sponsors. While for local communities the noise can have severe negative effects [...]

Introduction Wind turbine shadow flicker is the effect caused when a spinning turbine rotor causes brightness levels to vary within an affected room (although the precise definition can depend on [...]

Wind farms and radar Wind farm developments around the world face objections from radar operators. This is because large wind turbines can interact with radar signals, causing interference. Types of [...]

Previous articles: Radar concerns have rendered two turbines motionless Aveillant technology to mitigate the effects of two wind turbines at East Midlands Airport Overview Three years in the making, the [...]
