The FAA recently announced the launch of a new surface safety tool, called Approach Runway Verification (ARV), at air traffic control towers across the nation to improve safety at airports. ARV provides controllers with visual and audible alerts if an approaching aircraft is lined up to land on the wrong airport surface, or even the wrong airport.

In this week's video tip, we review how Class C and D airspace works, what you need to do to fly legally in it and how to stay safe.
