7.—(1) Within the United Kingdom an aircraft shall not carry out instrument approach practice when flying in Visual Meteorological Conditions unless:
(a)the appropriate air traffic control unit has previously been informed that the flight is to be made for the purpose of instrument approach practice; and
(b)if the flight is not being carried out in simulated instrument flight conditions, a competent observer is carried in such a position in the aircraft that he has an adequate field of vision and can readily communicate with the pilot flying the aircraft.
(2) For the purposes of this rule the expression “simulated instrument flight” shall have the same meaning as in rule 6.
