Additionally, there are special arrangements for non-radio aircraft based within the area, and special provisions have been made for microlight aircraft, hang gliders and balloons.
Although gliders are allowed to fly through airways, they are not allowed to climb up airways.
Moreover, in some airways, sharing arrangements exist which allow gliders access for soaring when airline traffic is low.
Many of our fast jet pilots were blooded in gliders of the air cadet movement.
Hang-gliders are not registered and no official records are kept of accidents.
In some areas there are to be found gliders and microlight aircraft.
The aircraft and the gliders take off and land on grass.
Further investigations are being carried out to determine the most appropriate colour schemes for other slower moving training aircraft and gliders.
