Surprises can generate additional problems

Hi,

Clandestino

In a K.I.S.S. approach:

1) An extra resource capable to inform UAS onset would be useful?

2) Block garbage to enter System would be better?


The crew processed adequately the surprises they received?

I would prefer to be informed immediately by an UAS detector resource than to be bombarded by the results (of the UAS) in the System.

False positives would be a problem? IMO, not.

My rationale is:

I donīt like the approach to diagnose UAS by System output. As showed in an Airbus SAS paper mentioned in an earlier post. This can be improved and in AF447 case seems very important.

Thanks to mention Solipsism. Rich issue. Maybe could be applied to Laser based AS sensors. Definitively not here in processing analog information coming from current technology. This is real long time ago.

I started my career using vacuum tubes (big ones in NDB, HF gear, etc.). In the Analog world.

The inputs i prefer (for my decision making) are analog signals. Not garbage processed by Systems.

Sadly, the (non adequately trained) crew of AF447 were:

Surprised by the System output and worse: Had to process garbage generated by the System.

And failed in their decision making. Actually, worse than that, never realizing (in time) what was going on...
