FIELD: transport.
SUBSTANCE: invention relates to method and system to control pressure in aircraft cabin. Proposed method and system to control pressure in aircraft cabin comprise determining the state of at least one aircraft door with the help of at least one indicator. Door state signal is sent to regulation unit incorporates with aircraft radio electronic hardware ventilation system. Aircraft radio electronic hardware ventilation system is controlled in response to door state signal so that in case door state signal indicates incomplete or unlocked door closure state, pressure increase in aircraft cabin is eliminated.
EFFECT: reliable prevention of excess pressure in aircraft cabin.
