Drones and model aircraft will not be allowed within 5km (3 miles) of an airfield perimeter when the rules come into force on 13 March.
The so-called drone "no-fly zone" had previously extended to around 1km (0.6 miles).
The new boundary includes a 1km-wide area extending 5km from the end of an airport runway.
It is already against the law to fly a drone above 400 feet (121.9 metres).
Violating the rules could lead to a prison sentence of up to five years.
The CAA says those who need to fly in the restricted zone - for example, to make a survey of a building roof at a low height - will be able to apply for a permit to do so.--SkyNews
