category at an aerodrome: see regulation 91.320 and section 2.02.
       (1) When conducting an authorised IAP in IMC, the pilot in command of an aircraft must ensure that the aircraft is operated within the range of, or at not more than the maximum, IAS provided for in subsection (2).
       (2) For any of the following:
(a) the specified aircraft performance category for the aircraft that is mentioned in an item of column 1 of Table 14.09 (2);
(b) a higher specified aircraft performance category than the specified aircraft performance category for the aircraft;
(c) subject to subsection (3), a lower specified aircraft performance category than the specified aircraft performance category for the aircraft;
        the aircraft must be operated within the range of speeds, and at not more than the maximum speed (as the case requires), specified in columns 2, 3, 4 and 5 of the same item.
Note   Lower and higher aircraft performance categories are specified in section 2.02. The aircraft performance categories are, from lowest to highest, H, A, B, C, D and E, and in items 1, 2, 3, 4 and 5.
       (3) For paragraph (2) (c,) the aircraft must not be operated at a lower specified aircraft performance category unless the operator of the aircraft:
(a) holds an approval under regulation 91.045 for regulation 91.320 to operate in the lower specified aircraft performance category; and
(b) has complied with subregulation 91.320 (3).
Note 1   For example, an aircraft whose specified aircraft performance category is B, may conform to the requirements of aircraft performance category C. But an aircraft whose specified aircraft performance category is C must not attempt to conform to the requirements of aircraft performance category B without CASA approval and operator compliance with subregulation 91.320 (3).
Note 2   Subregulation 91.320 (3) requires an operator holding the relevant approval to give details of the approval, and the conditions (if any) imposed by CASA on the approval, to the flight crew of an aircraft conducting a flight that uses the approval.
