We have reported that some flights to and from London’s Heathrow Airport would be disrupted on Monday, in order to guarantee quiet conditions for the Queen’s funeral.
Flying restrictions have also been imposed over central London and Windsor on the same day.
The Civil Aviation Authority (CAA) says no aircraft, including drones, will be permitted to fly below 2,500ft (762 metres) over areas where services are taking place.
The CAA says the ban – which includes small balloons and kites – is necessary for security reasons.
