Hi,
UNCTUOUS:
... - to "in your face" alert the crew of an imminent GIGO fiasco (GIGO = garbage in/ Garbage out)
You need a licenced decision-maker on scene.
Capable to understand precisely and fast whatīs going on. What requires a lot of multidisciplinary knowledge. Training is enough?
- particularly when the failure is epicentric and tentacular. The omnibus checklist series that covers all contingencies is yet to be written.
Statistically, a perplexed crew is around 50% unlikely to come up with a workable solution when suddenly faced with "the unstraightforward".
So, SURPRISES to the crew must be reduced to a minimum. Why not to ALERT CREW IMMEDIATELY when the System will face UAS? This is particularly important because there are risks of GIGO.
The evident need is always to minimize trouble-shooting...Automation to date has been designed to alleviate the normal workload. Its next generation and obvious development challenge is to relieve the abnormal workload.
Congratulations! I was concerned with all this when started this Thread:
Man-machine interface and anomalies
The increasing technological sophistication in FBW planes brings benefits and challenges to the pilots and other 'players". The objective here is to discuss the "interface" and itīs components, specially when facing anomalies.
Rather than just "blacking out", it would (IMHO) be infinitely better for a suddenly unreliable instrument or screen to either:
a. show on its face a clear exposition of its failure status (or of faulty input data being out of limits).. or...
b. simply show vertical or horizontal raster (think of the older analogue screens with a faulty vertical hold) - i.e. its "out of action" status.
Just flickering or failing to zero or displaying a false reading or even an unobvious non-annunciating OFF flag is wholly unacceptable - but that's exactly where we are "at" now.
Its exploitation needs to now include some deeper systemic introspection and a non-misleading advisory capacity.
(Bold mine)
Developments in avionics systems now needs to concentrate upon
the human interface.
R&D, a complex one, is required.
That's the way to go.
I agree completely!
Thanks for excellent post!
