amanoffewwords,

I see you're not from the Midlands!!!!

While I'm here, here's another that was buzzing over me:




Max Con is obviously completely ignorant in the operation of Police Helicopters.

"how nice it was that they turned up completely unexpected"
Sorry, we'll give the crims a phone call in future so they can make a getaway!

"how the crew amazed the crowd with such skill at low level"
It's not difficult to impress the unknowing.

"how you were previously unaware that a rotor craft could be manoeuvred in such extreme ways"
Well, I hope you have now learnt from the experience! Join us on our next inner city pursuit!

I'll just get this hook out from my cheek!!

By the way, it's not a 'loop', but a low speed route reversal!!


wg_13,

Isn't the torque value based on the gearbox limitation and not the engine!!! Even at a 100% TQ, isn't the engine still only working at about 60% of its capability. It's a powerful engine the Gem!

The Nr & Nf needles are set at '107% Nr' as that is the result of the SSL selection after start up. Bonk tuning?
As your pics show, at 120kts the SSL should be adjusted to give 104.8%. Primarily, isn't this to give 104.8%NR in order to reduce airframe vibration and therefore a smoother flight?
