ATR systems - Ventilation and pressurization

Cabin pressurization is, together with the jet engine, the invention that made modern air travel possible. This allowed the airplanes to fly above turbulence and icing. And being a passenger suddenly became more comfortable.

This video examines the ventilation system and the pressurization system in ATR 42 and 72. Other transport airplanes have very similar systems.
