Looking to the future one must consider a continuous HUMS assessment in flight. Should a HUMS computer be able to download information and analyse the results after a flight then surely it must be within the wit of man for it to be able to do it en-route. The processing capacity to launch an Apollo Lunar Mission is now available in something not much bigger than a smartphone so weight and volume should not be a problem.
How much safer would it be if a HUMS panel would warn you of an unusual occurence within your systems or the reassurance of being able to press a check button on it to ensure that everything is normal.
When HUMS first started all those years ago what we wanted was a light that said. "Do not fly this aircraft."
