Thank you guys ! Am already in contact with CAA Desk Officers, have emailed ICAO (no reply yet), and will obviously need copy of AIP (just do not have this as yet). As per CAP 722 I'll await the new version, so thank you - and yep, have read present issue of CAP 722 so am aware of its coverage. However, although <20kg in practice there are issues with flight control (e.g. autonomous or remote), max allowable range and ceiling, for example, and fact CAA covers UK airspace only really here - hence a part of reason for asking the international rules aspect (for all aircraft types at low level and UAVs/Remote Controlled aircraft)
Thanks for all your help ! Hope all's well with you !
