I found out today that NATS ― the National Air Traffic Service, i.e. the organisation responsible for air traffic control in the United Kingdom ―  has released its own app to aid drone pilots in planning their flights, called NATS Drone Assist.

I have tried it out immediately ― being on the lookout for a new planning tool since the Hover disaster ― and found it to be excellent.  Not only are the VFR maps up to date and very interactive and include NOTAMs and future use indicators, but the app also warns of other hazards, including high-voltage lines and other drone users that are currently active.

NATS has also endorsed AirMap, the app I have been using since abandoning Hover.  So, I guess that if I use the app released by the air traffic control people and the app recommended by the air traffic control people, I hopefully will not go too badly wrong in the future.
