Super VC-10, That is a most erudite question. To cut to the quick, I don’t know in definitive terms, but having said that, surely the synoptic would be useless if it did not show the result, rather than the request?
Having said that, I do recall being told that some of the valve positions on the bleed air page could be misleading, but in this day and age of "you don't need to know that", it was never expanded upon.
As the aircraft is intact, all should be revealed in the near future.
