Environment Control System (ECS)

The ECS creates comfortable air temperature, humidity, and pressure conditions.

When MC-21 aircraft flies at the altitude of 11,887 m (39,000 ft), the in-cabin air pressure equals the pressure at the altitude of 1,830 m (6,000 ft) above the sea level. This provides positive effect on passengers’ and the crew’s health.

Three-zone temperature control maintains comfortable flight conditions for all passengers.
