Unanswered Question ...

Bismillah,

Well ... during RC-ASTI 2007 yesterday there were 2 questions asked regarding my topic of presentation. But alas, I couldn't give a satisfaction answer due to the time given. So since it was asked in English it is my obligation to answer it in English as well.

I forgot the details of each questions but I am trying to remember your questions ... so if you read this post please send your detail question(s) ... :)

Q1:

Would there be a chance in NBAS to provide an emergency landing route to pilots?

A1:

Yes, that's possible. In this concept we are working now ... a set of servers providing information for landing such as geographical contour, minimum glideslope, outer-middle-inner marker bound together with GPS data obtained from aircrafts form significant emergency routes even wide-body aircrafts could follow.

The idea is, geographical contour restricts air routes during landing phase. So within the database which covers GIS, weather, air routes, and even stores aircraft current status from ACARS (A-ircraft C-ommunication A-ddressing and R-eporting S-ystem); authorities could establish safety route based on aircraft current position, geographical contour plus weather condition ... stored into the spatial database and later sent to aircraft so pilots manage to "sense" what route(s) they should follow for safe approach and landing afterwards.

As a consequence ... in all cases, aircrafts data communication interface must have and IPv4 or IPv6 address. This is possible, very possible.

Q2:

Do you mean that only ATC (Air Traffic Controller) can access internet to obtain information you mentioned above ?

A2:

At this present, yes. But in future development not only ATC that can monitor aircraft positions but also the authorities such as KNKT (K-omisi N-asional K-eselamatan T-ransportasi) or SAR (S-earch A-nd R-escue) whenever an aircraft is declaring an emergency so we expect no information ambiguity on where the aircraft ditched or crashed or even missing.

We have a serious concern on the loss of Kilo-Kilo-Whiskey flight KI-547 early this year that was ditched somewhere in Makassar Strait; until the CVR (C-ockpit V-oice R-ecorder) and FDR (F-light D-ata R-ecorder) are retrieved, we have no idea how and why the aircraft was missing. So by this concept, we could predict how ... where ... and why an aircraft crashed. A complement of FDR and CVR peripherals I would say ...

--oOo--

We know that our development is still a long journey but we are trying to formulate this concept to the directorate general of civil aviation (DGCA), air worthiness certification section (DSKU), and FAA/ICAO as international flight regulation boards.

All in all, we are trying to make aerial transportation even more safe than earlier. We just don't want aerial disasters like KI-547 are left stateless for 8 months !! We are just trying to minimize aerial disaster as low as possible ... in 4JJ1 Name.
