Helicopter Training Exercise at Metropolitan Police Peel Centre on 25-04-2013 

Ben White I thought that heli was only for sas. So a terror incident happens and ct takes it, does the sas have wait?i doubt they’ll give them that and most like sas would deal with these high risk things. Just my opinion. Plus the police have their own helicopter why do they need that to train and I’ve seen them use their own helicopter.

No they sound exactly the name. If you know anything about helicopters. The reason it sounds different is these helicopters are older and the fenestron tail rotor. The new ones the tail rotor blades are not Asymmetrical. They have the blades spaced different and it creates a node which produces a lower pitch sound. This helo here has its tail blades spaced equally and it creates a higher pitch sound. The high pitch sound is not the engines it’s the tail rotor. I’ve flown lots of eurocopters or airbus now. So I’m very familiar with the design. The very first dauphins would scream extremely loud. Until they figured out how to space the blades to bring the pitch down.

You may wish to consider rewriting this in a language that normal people can understand.
