CPC A61B 5/18 (2013.01) [A61B 5/742 (2013.01); A61B 5/746 (2013.01); A61B 5/7475 (2013.01)] | 17 Claims |
1. An aircraft crew operational state monitoring system comprising:
a first interface configured to receive first crew monitoring data, the first crew monitoring data having a high design assurance level;
a second interface configured to receive second crew monitoring data, the second crew monitoring data having a lower design assurance level than the first crew monitoring data; and
a pilot state determiner configured to determine at least one monitored pilot state based on the high design assurance level first crew monitoring data received from the first receiving interface, and based on the lower design assurance level second crew monitoring data received from the second receiving interface,
for the at least one monitored pilot state, the pilot state determiner being configured to implement a first deterministic algorithm to obtain a high-level pilot state from the high design assurance level first crew monitoring data, regardless of the lower design assurance level second crew monitoring data;
the pilot state determiner being configured to determine a low-level pilot state, from at least the lower design assurance level second crew monitoring data;
the pilot state determiner being configured to determine a consolidated pilot state, the consolidated pilot state being obtained in an active configuration of the low-level pilot state determination as a function of the high-level pilot state and of the low-level pilot state, and is obtained in an inactive configuration of the low-level pilot state determination as a function of the high-level pilot state, without taking the low-level pilot state into account.
