Passenger aircraft includes seats, display screens facing the seats, and oxygen masks. When oxygen masks are deployed, imperative imagery is displayed that urges the passenger to at least don their oxygen mask, then optionally help others, etc. In some of these embodiments, the passenger aircraft further includes input devices. Each passenger can enter an input that indicates they have donned the mask, so as to see further imagery for guidance. These inputs could be stored in the flight data recorder for subsequent analysis. In some embodiments, passengers enter self-reported data using the input devices. The self-reported data can be stored in the flight data recorder for subsequent analysis of situations, such as when oxygen masks have been deployed.
