FFS - maybe this is why I haven't posted for a while...........
Whilst it may seem obvious what the aural notifications may or may not have been, I want to know if its fact and if so where does it state it. Two engineers that I have spoken to and a number of EC120 pilots aren't aware of any aural indication without an associated caption and so if it is an early indicator, what is it an early indication of?
What's the parameters that cause a single notification versus a double 'bong' ?
Does it give an indication of any failure or is it specifically for the main engine oil ?
If it's an indication of a failure of anything then what point does it serve if it doesn't give you an idea of what the failure might be?
The aural warning on its own therefore doesn't actually tell you anything unless it's only evident in one type of malfunction...........
To answer one of the other questions, no there were no other indicators , all T's and P's were in the normal ranges and my engineer had cleared the aircraft to fly subject to certain parameters which were maintained.
