title_body: How do certified drone operators ensure they're not harassed by the police while filming from their drone?
upvoted_answer: Look the part - wear a high-visibilty jacket with a company logo, &quot;UAV Pilot&quot; or other markings that makes you look like a professional.
  Put up a sign which explains who you are and what you are doing - &quot;Drone Filming In Progress - please wait until aircraft is landed before approachng pilot. Operator: SuperDronePics Ltd, Permit number: OP-4ME33NK.&quot;
  Where possible, fly with an observer/helper who can intercept interested people (police, public, etc.)
  If you are flying somewhere particularly likely to attract attention, it may be worth contacting the local non-emergency number in advance. I don't expect they'll post an officer with you thoughout the flight, but it could help to cover phone calls from the public - and perhaps a police officer who radios in before approaching you.
  
  Finally, always have all your paperwork ready to show - if you are interrputed, it looks more professional to have a folder with your permits, insurance, etc. at hand. While police interest might become annoying (especially when repetitive!) you are almost always better off just answering their questions and being helpful.
