Based on lessons learned from past airline accidents, the FAA regulation stipulates precise design details for the warning displays in the cockpit. These are aimed at ensuring that alerts relay clearly to the pilots what’s going on when a malfunction occurs, catch attention so that they won’t be overlooked, and avert any possible confusion.
During the two fatal MAX crashes that killed 346 people, pilots struggled to understand the cascade of warnings in their cockpits. Last week a National Transportation Safety Board (NTSB) report on those crashes highlighted the crucial role that crew alerting systems play when pilots face an inflight emergency.
You will notice the contradictory requirement the alerting system is to relay clearly what is going on - and catch attention so they will not be overlooked
this is the cascade of warnings and information AND avert possible confusion
caused by the cascade of required alerts and information.
So
all malfunctions must be alerted
in a way that cannot be ignored AND avert possible confusion? It is the mass of cannot ignore alerts that
cause the confusion.
