Thanks for the input but as Rockeyes says it would be great to see a source that backs this up. Not to question your expertise but there are so many claims and counterclaims that what we really need is an official document or source that clearly states the rules for this R160 area.
157, 158 and 159 are all clearly marked on the NATS app as “DRONE NO FLY ZONE” (with the notes adding “unless prior approval”
Since they’re contained within R160, it would seem far important that R160 is labelled as a NO FLY ZONE if that’s the case.
Of course, currently you aren’t able to fly anywhere in R160 without violating the drone code since you’ll always be <150m from a built-up-area. So maybe they’ll clarify come Jan 1st?
