Thanks for more info guys,
Have discussed with client and blending in with Military is not an option. Strict instruction is to appear as non mil as possible.
Neither will there be any scope for night ops with or without NVG.
No guns either - totally civvie ops.
Only pax transfer during daylight.
We'd assumed on varying routes but the approach changes make sense too, thanks. Already doing spirals in there with fixed wing (now you can guess where I am talking about...) so could adapt that a little.
139 is also a good choice, agreed. Ordered a couple already but delivery is not till late 2006 or into 2007 and 109 Grand won't work.
Thanks again !
