“The salvage crew who had raised the wreck of the Tornado had done an excellent job and amongst their finds was the CVR; thus we had a tape recording of the final moments. When this was played one thing was immediately apparent: there was NO aural fire warning!! Nor was there a visual warning on the MWS.”
A very enlightening post. No aural warning. No visual warning. That smacks of lack of proper systems integration (or poor servicing). And, bears a remarkable resemblance to similar omissions on the Tornado lost to friendly fire during GW2, as noted in the BOI report.
This is not a criticism, because senior DPA staffs have specifically ruled that it is in order to deliver aircraft without such emergency systems properly integrated (Boscombe and some PMs disagree), but this merely emphasises yet again that perfectly serviceable systems can present no warning or indication that something is wrong because they have not been properly integrated (as a system of systems). In the case of emergency systems (at least) this would break the airworthiness chain – something discussed a lot recently on ZD576.
