In episode one of Skies Above Britain my colleague, Brian Wheeler, explained some of the impact fog can have on our operations. While we continue to enjoy the summer months, we’d rather forget that around the corner lie the misty and foggy mornings of autumn. But what exactly does fog mean for an air traffic controller?

During periods of bad weather such as fog, control has to switch to radar and ‘low visibility procedures’ to ensure airport operations can continue safely.
