Hi Savoia,
Thanks for the welcome.
I don't have permission from the client to give details of the site but the landing site is about 20 to 25 metres from the proposed edge of the wood. To preserve hydrology in the wood, the nearest tree line will be scalloped to slow down the wind. I can plan the safe clearance into the scalloping when I know what the safe distance is.
My understanding of private sites is... planning permission isn't required if the landing site is within the curtlege of the property, or if in an adjoining field if the landing site is used no more than 28 days out of a calendar year.
Never in a million years did I ever think that as a woodsman, I would be consulting with pilots about the pros and cons of planting trees!
Thanks again.
