The particles rising with the upward airflow are recovered as the top product, while the falling particles are recovered as the bottom product. The recovery of the lighter fraction is the mass of the lighter fraction in the top product divided by the massAirspace Classes Explained - Bobbie Lind,Airspace Classifications. The FAA’s Instrument Flying Handbook lists six airspace classifications for the U.S.: Class A: Airspace that begins at 18,000 feet MSL (mean sea level) up to flight level (FL) 600. This includes airspace over waters that are within 12 nautical miles (NM) of a coast.Air classifier - Wikipedia,An air classifier is an industrial machine which separates materials by a combination of size, shape, and density. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air. Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air. Due to theIntroduction to Airspace - NATS,Airspace within a FIR (and UIR) is usually divided into pieces that vary in function, size and classification. Classifications determine the rules for flying within a piece of airspace and whether it is ‘controlled’ or ‘uncontrolled’.

CleanroomIntroduction to Airspace - NATS,In the UK there are currently five classes of airspace; A,C,D,E and G. The classification of the airspace within a FIR determines the flight rules which apply and the minimum air traffic services which are to be provided. Classes A, C, D and E are areas of controlled airspace and G is uncontrolled airspace.
