Anybody who'd like info on the BAE IHUM system fitted to the N Sea aircraft can turn to
http://www.hums.com/humsindex.htm
They have about 150+ aircraft fitted worldwide. S61/S76/AS332/Bell 212/Bell 412/ AS365.
Another site of interest may be
http://www.shl.co.uk/Technologies/Pages/homp.htm as this is the FDR data recorded in real time, fed from the IHUM system.
And I never mentioned pilots pay once.
