I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Park in residential areas to the east or the west of the site.
There are plenty of public footpaths around the site.
I took off near the Lawford Road junction of the A4071, near a footpath that joins Somers Road, as this hides you from the main dual carriageway traffic and makes it a bit easier to take off and land.
The west side of the plant seems to be a bit of a signal black spot, I lost signal a couple of times. If you want to get the whole sight without losing signal and keeping VLOS then I’d advise walking to the public footpath area to the north of the site near the River Avon. There is plenty of green space here to take off and land without any disruptions.
You can also get some trains while you’re at it from the either side of the Rugby junction.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 08/04/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
