A cabin pressure control system and method improves cabin pressurization during aircraft take-off operations. The cabin pressure control system sets a cabin pressurization rate limit based on a cabin pressurization rate error. The cabin pressurization rate error is derived from a comparison of a sensed cabin pressure rate-of-change value and a predetermined cabin pressurization rate value.

A method for reducing false detects may include emitting an infrared light beam from a primary emitter to a primary monitor detector, measuring a first voltage value using a primary receive detector and setting a primary smoke alarm flag corresponding to a primary channel if the first voltage value is above a first threshold value. The method may also include measuring a second voltage value using a secondary receive detector, setting a secondary smoke alarm flag corresponding to a secondary channel if the second voltage value is above a second threshold value and setting an alarm indicating a smoke condition if the primary smoke alarm flag and the secondary smoke alarm flag are set.

An optical particle counter generates a signal indicating an amount of radiation scattered by aerosols in a sample flow. Smoke can be discriminated from other aerosols in the sample flow by analyzing the AC component of the signal. Smoke has a much higher signal-to-noise ratio than that of larger particles such as dust and fog.
