Ambient condition based adjusting of cabin pressure to achieve target aircraft inflow

摘要

Embodiments relate to adjusting cabin pressure based on ambient conditions to achieve a target aircraft inflow. An aspect includes receiving a number of occupants on an aircraft. The ambient conditions on the aircraft are monitored and an occupant threshold limit is determined for the aircraft based on the ambient conditions. If it is determined that the number of occupants exceeds the occupant threshold limit, the cabin pressure is reduced in the aircraft according to embodiments. The cabin pressure in the aircraft is reset in response to the occupant threshold limit being increased due to changing ambient conditions.

1. A method, comprising:
receiving a number of occupants on an aircraft at a processing device; monitoring, by the processing device, ambient conditions on the aircraft; determining with the processing device an occupant threshold limit for the aircraft based on the ambient conditions; signaling a cabin pressure controller to reduce cabin pressure in the aircraft when the number of occupants exceeds the occupant threshold limit; and resetting the cabin pressure in the aircraft in response to the occupant threshold limit increasing due to changing ambient conditions; wherein the occupant threshold limit is a number of occupants that can be supported by a flow source without exceeding a maximum cabin temperature, the occupant threshold limit a function of ambient temperature, altitude and aircraft speed.
