(3) Paragraph (2) shall not apply to an aircraft which—
(a)flies at or below 3,000 feet above mean sea level;
(b)remains clear of cloud with the surface in sight; and

(4) Paragraph (2) shall not apply to an aircraft which—
(a)flies at or below 3,000 feet above mean sea level;

(d)is in a flight visibility of at least 1,500 metres.

(b)obtain an air traffic control clearance to fly within that airspace.
(2) The flight plan shall contain such particulars of the flight as may be necessary to enable the air traffic control unit to issue a clearance and for search and rescue purposes.
(3) The flight plan required for a flight within Territory reduced vertical separation minimum airspace shall also state whether or not the aircraft is equipped with height keeping systems, as required by articles 51 or 52 of this Order.
(4) The pilot-in-command of an aircraft shall not cause a flight plan to be communicated to the appropriate air traffic control unit for VFR flight in Class C airspace above FL195 or along a Class C ATS route at any level unless authorised to do so by the Governor.
30.—(1) Subject to rule 31, whilst flying within Class B, Class C or Class D airspace during the notified hours of watch of the appropriate air traffic control unit, the pilot-in-command of an aircraft shall—

(b)comply with any instructions which the appropriate air traffic control unit may give.
31.—(1) Rule 29 shall not apply if the aircraft has otherwise been authorised by the appropriate air traffic control unit.

(a)flies during the day;
(b)is in controlled airspace notified for the purpose of this paragraph; and
(c)remains at least 1,500 metres horizontally and 1,000 feet vertically away from cloud and in a flight visibility of at least 8 km.
(4) Rules 29(1) and 30 shall not apply to any mechanically driven aircraft without radio equipment if—
(a)it flies during the day;
(b)it is in controlled airspace notified for the purpose of this paragraph;
