Causes and solutions vs justifications to do nothing...
In this case UAS was an incident where no intervention was actually required, just keeping Normal Law in force. With 3 A/S data loss, but knowing that A/S cannot suddenly change on large scale without a considerable acceleration being sensed , with at least 2 principle different source of data for speed (GPS, and inertial – acceleration derived ) – results that ‘simple’ changes are ‘at hand’ to software engineers for preventing pilot to be suddenly put in the control loop, when at least a warning time would be much more appropriate if not even allowing temporarily discrepancies/anomalies to be surpassed (and I am curious, in how many similar cases the time for ‘appropriate reactions’ of pilots and return to the initial trajectory were larger than duration of speed anomalies) .... .
But – no changes for speed sensors, no changes for F/Ctl software, no changes in pilot training – how many years?
And these not thinking about other means possible to develop: wing load can easily be deducted measuring strain in wing structure (using tensiometric sensors f.e.), wing deflection can easily be measured also, the conclusion is that flight being nowadays a mass service, authorities, insurers, carriers (in a word the whole industry ) treat it more and more as volume,( not quality/safety) driven.
Unfortunately , as in many other trades, the lie stay in what is not told to customer (or rarely escaped, and with smallest font written) and even to industry professionals too. It seems that remain to judges to make that policy too expensive, (but, little hope too...)
