Why would we want a high and low RPM horn?
lower speed beeping for low Nr, higher speed beeping for high Nr - works an absolute treat
Crab I agree 100% with all you say. For the Low Aural Warning it works when the pilot is not over aroused (startled) but how many times do we see this aural warning being ignored when the brain is saturated
that's where you come in - teaching them the importance of it in the sim so that it becomes an automatic response.
The only trouble is there are so many aural warnings in a modern helicopter that it can be difficult to work out which is the most important.
