Tees,
An excellent idea provided it is part of a systematic approach to the issues of eTODs and Electronic Visibility. It could even work for local let-down implementations - as provided in Norway.
One impression that was gleaned from the conference was that, what little is being done to address the improvement of operations in DVE (e.g. PROuD), is not part of joined-up thinking by SESAR on future airspace management. They appear to have little appetite for anything that is not related to large aeroplanes (nor operations out of controlled airspace).
There also appears to be little discernible public debate even when it is blindingly obvious that a properly constructed let-down procedure might have provided a break in the accident causal chain - for example in the Irish SAR accident (not even mentioned at the recent RAeS conference). There were one-or-two passing references in the PPRune thread but it was not, perhaps, acknowledged as a primary cause of the accident. Hopefully it will be fully covered by the IAAIB when they report but might have been addressed in the interim report.
We, in Europe, also appear to be miles behind the current work on UAS Traffic Management (UTM) that is well down the planning route and being driven by NASA/FAA in the US.
