Regular free-fall parachuting from up to FL 150 takes place at a number of sites (marked on UK CAA Aeronautical Charts and listed at UK AIP section ENR 5.5) and within several Danger Areas. The sites include a number of licensed and government aerodromes but parachuting may also take place at any licensed or government aerodrome. Night parachuting may also take place and this activity will be promulgated by NOTAM.
Once parachutists have exited the drop aircraft their ability to manoeuvre is severely restricted. Visual sighting of free-falling bodies is virtually impossible and the presence of an aircraft within the Drop Zone may be similarly difficult to detect from the parachutists’ point of view. Pilots are strongly advised to avoid flight through airspace where parachuting activities are notified as taking place. Pilots are also advised to assume the Drop Zone is active if no information can be obtained from the NATSU. Reference to specific FFDZs can be found in the ENR section 5.5 of the AIP.
Bird Sanctuaries
A number of areas in the United Kingdom have been designated sanctuaries to provide an undisturbed environment for birds to breed and roost.
Similarly, offshore islands, headlands, cliffs, inland waters and shallow estuaries attract flocks of birds for breeding, roosting and feeding at various times of the year. In order to lessen the risk of bird strikes pilots should avoid overflight of such locations below a height of 1500ft. Where it is necessary to fly lower pilots should bear in mind that the risk of a bird strike increases with speed and that birds rarely hit an object moving slower than 80kt.
