Thank you so much for your replies so far. I think flushvisions approach of looking professional and official must make a difference. I have approached a couple of local farm owners for permission to fly from fields that are currently lying fallow, both of whom are good acquaintances, and I approached the local school and rugby club for permission to fly from their playing fields when they are not in use but was met with 100% refusal. Everyone seems to be obsessed by the perception that drones are a means of spying or intruding upon folks privacy. Maybe I have just been unlucky.
Regarding bath racecourse I have attempted to fly at the playing fields adjacent to the park and ride near the racecourse but it is tricky to pick a time when there are few other people there. Maybe very early in the morning would work
Soon I am off to the new forest but they are now anti drone emphasising the bylaw that prohibits any model aircraft except on the beaulieu model aircraft club location but even that club tells multicopters to take a hike (I n the politest terms of course) I don't really want to flout local bylaws and thus give drone users a bad name but I have to confess I am increasingly tempted!! In a massive unoccupied area it should be perfectly easy to make sure one follows the drone code and avoids annoying any people or animals. But hey I'm still resisting that temptation for now!
I'm not surprised that a school will refuse to give a permission. If it is an academy, then the school headmaster will probably not be in a position to grant a permission since the land will be owned by whatever company owns it and will not necessarily be the actual school. Further, It is not under the control of the council. If you want to get a permission to fly there you will have to present a case to the body that owns it...which will not necessarily be the school itself. If you look on Altitude Angel's safety map you will notice that schools are designated as sensitive areas. I do some of my testing on a school's playing fields when the school is closed for holidays. It is an academy and I obtained a permission not from the school who doesn't own the land. I got my permission from the actual land owners.
To fly from council owned land: Before a council are likely to grant a permission they will most certainly want to see adequate Public Liability Insurance and possibly a safety statement from you. Get in touch with your Parks & Recreational Services Department (or whatever they call themselves in your area) to see what hoops you have to jump through to fly from their land. Contrary to wide belief (in the U.K.) some local councils are not apposed to the flying of UAVs from their land if you can demonstrate adequate safety measures. For example, Heaton Park in Manchester is drone friendly provided that you fly within the Drone Code.
As far as I'm aware, it is legal to take off from a public footpath provided that the flight is done within the drone code. Yes, you may get some shirty person moaning but so long as you are on a public footpath I believe you are technically legal to fly from there.
Don't take this as gospel, but if someone objects to your flying and threatens to call the police, then so long as you are flying legal, let them. Don't get into an argument. Don't even acknowledge them. Fly your current battery then land. Pack up and move on. The likelihood that the police will arrive before you have long gone is fairly remote since the police have far more important things to deal with. A report of a drone flight will be fairly low on their priorities. Further, if they do arrive before you have gone and they can see you are flying legally they
should leave you alone. If they see you are being a bit naughty, but not dangerous, they are more likely to just warn you not wishing to get involved with all that nasty paperwork.
In short. So long as you are not trespassing and are flying within the drone code you should be OK. Note that in the U.K. it is legal to fly over private land (I suggest not too low) but you need permission to take off from private land. Remember that some public land may be owned by the council.
If you haven't already got one, then get a High-Vis vest. Dream up a company sounding name and have it printed on the vest. Get insurance. Insurance will go a long way towards getting permissions.
In the years I've been flying multirotors I've only had two instances with people objecting.
I hope my ramblings will help you.
