(5) An aircraft shall be exempt from compliance with:
.......
(c) paragraphs (1), (2), (3) and (4) when practising approaches to, or
checking navigational aids or procedures at, a Government
aerodrome or licensed aerodrome in the United Kingdom, or at any
aerodrome in any other country, while utilising the airspace

Old Rule
(4) (a) Subject to sub-paragraph (b), nothing in this rule shall prohibit any aircraft from flying in accordance with normal aviation practice, for the purpose of taking off from, landing at or practising approaches to landing at, or checking navigational aids or procedures at, a Government aerodrome, an aerodrome owned or managed by the Authority or a licensed aerodrome in the United Kingdom or at any aerodrome in any other country.
