Without prejudice to any power of an aerodrome operator to enter into an agreement on such terms as he or it thinks fit, an aerodrome operator may with the approval of the Minister and for the purpose of encouraging the use of quieter aircraft and of diminishing inconvenience from aircraft noise, fix his or its charges by reference, among other things, to any fact or matter relating to-(a) the amount of noise, vibration or emission caused by the aircraft in respect of which the charges are made; or
(b) the extent or nature of any inconvenience resulting from such noise, vibration or emission.
