Silsoe,
Don't you start! Were mates now !
And why do you feel the need to quote my 'credentials' you can clearly see that I posted that only because I was challenged in the original reply to my first post - don't you start adding fuel!
Now, to answer you, I don't 'mean' anything - my whole post is basically asking for a steer as to what might have happened to have caused him to not react quickly enough - surely my post is in plain enough language for anyone to understand that - I'm asking!!
For instance is it possible that his hand wasn't on the collective for whatever reason or that the collective was locked with friction or the autopilot was engaged and it takes 1 second to disengage but the RRPM decays in under that time.
In my machine, if my engine fails (god forbid) I get an engine out tone, I get un commanded yaw and I drop the lever quick. But my machine also allows me something like two seconds in which to do it. Does the EC135 allow such a time frame?
However, if I had a passenger who panicked and grabbed my arm or I was switching my pitot heat on or changing frequency at the point my engine failed maybe those action could cause me to react more slowly and the RRPM might decay to an un-recoverable point. In this case whilst the manufacturer might consider in a calm cockpit with no other distraction there is traditionally
sufficient time to lower the lever there are factors like those I've described that might cause there to be
NOT sufficient time to react. It's not rocket science!
If there were warning captions illuminated, aural tones, and procedures that he had to follow etc that distracted him, plus pax that might have been talking to him or were panicked causing him to not instantly realise that he'd had a double flame out then he may not have had
sufficient (as in humanly possible) time to process the information that his brain was dealing with and consequently not lowered the lever quickly enough.
None of us were in that cockpit so no one knows what happened but I'm asking for a steer from someone like you who flies twins and understands the systems and processes that might have lead to that. Finally, should the fuel transfer switches been on or off, because I don't think that's been answered.
The point is, I don't know, which is basically why I'm asking!!!!
Come on Silsoe! I'm relying on you for a sensible answer now that you've waded in!
Joel
