1 Name of Order This Order is the Civil Aviation Amendment Order (No. R6) 2004. 2 Commencement This Order commences on gazettal. 3 Replacement of section 20.7.1 of the Civil Aviation Orders Section 20.7.1 of the Civil Aviation Orders is omitted and a new section substituted as set out in Schedule 1. Schedule 1 Substitution of section 20.7.1 of the Civil Aviation Orders

SECTION 20.7.1

AEROPLANE WEIGHT LIMITATIONS — AEROPLANES ABOVE 5 700 KG — ALL OPERATIONS (PISTON-ENGINED)

1 APPLICATION This section applies to piston-engined aeroplane types having a maximum permissible all-up weight in excess of 5 700 kg and which were registered in Australia prior to 1 June 1963. 2 TAKE-OFF WEIGHT LIMITATIONS 2.1 An aeroplane shall not take-off at a weight in excess of the weights determined in accordance with subparagraphs 2.1.1 to 2.1.4 of these Orders: 2.1.1 The permissible all-up weight as specified in its Certificate of Airworthiness. 2.1.2 The maximum take-off weight specified in the relevant Aeroplane Flight Manual for the altitude above sea level of the aerodrome concerned. 2.1.3 The lesser weight of either: (a) the permissible landing weight at the destination aerodrome calculated in accordance with paragraph 3 of these Orders plus the weight of fuel that would normally be consumed in flying from the departure aerodrome to the destination aerodrome; or (b) the permissible landing weight at the alternate aerodrome calculated in accordance with paragraph 3 of these Orders plus the weight of fuel that would normally be consumed in flying from the departure aerodrome to the alternate aerodrome. Note: Subparagraph (b) will apply only when the flight plan includes an alternate aerodrome. 2.1.4 The weight calculated from the relevant current CASA Take-off Weight Chart or approved Company Take-off Weight Chart for the aerodrome type concerned in conjunction with either: (a) the corrected effective operational length of the runway to be used for take-off under ambient conditions; or (b) the appropriate seasonal declared density altitude taken in conjunction with either: (i) the corrected effective operational length of the runway for take-off under no wind conditions; or (ii) the corrected effective operational length of any subsidiary runway for take-off under the minimum head-wind component that may result when the main runway cannot be used due to excessive cross-wind component, whichever gives the lesser weight. Note: The weight calculated in accordance with subparagraph (b) (ii) above shall not apply to a subsidiary runway which is listed in the Operations Manual as being unsuited for take-off by the type of aeroplane concerned when using declared weight. When it is desired to use a subsidiary runway which has been so listed in the Operations Manual the take-off weight shall be calculated using the methods specified in subparagraph (a) of this paragraph. 2.2 Where, prior to the take-off, a significant change occurs in the value of any factor used in computing the permissible take-off weight which would have the effect of requiring a reduced all-up weight from that already computed, then a new all-up weight shall be calculated using the new value for the factor(s) concerned and the weight so determined shall be the maximum weight to be used for take-off. 2.3 Take-off weight charts which enable compliance with this Order are available on application to CASA. Instructions for the use of these charts are provided at Appendix 1. 3 LANDING WEIGHT LIMITATIONS 3.1 Except in an emergency, an aeroplane shall not land at a weight in excess of the least of the weights determined in accordance with subparagraphs 3.1.1 to 3.1.3 of these Orders. 3.1.1 The maximum permissible landing weight as specified in its Certificate of Airworthiness. 3.1.2 The maximum landing weight specified in the relevant Aeroplane Flight Manual for the altitude above sea level of the aerodrome concerned. 3.1.3 The weight calculated from the relevant CASA Landing Weight Chart or the approved Company Landing Weight Chart for the aeroplane type concerned in conjunction with the forecast pressure and temperature or the appropriate seasonal declared density altitude with either: (a) the corrected effective operational length of the main runway for landing under no wind conditions; or (b) the corrected effective operational length of a subsidiary runway for landing under the minimum head-wind component that may result when the main runway cannot be used due to excessive cross-wind component, whichever give the lesser weight. Note: The weight limitation calculated in accordance with subparagraph (b) above shall not apply to a subsidiary runway which is listed in the Operations Manual as being unsuited for landings for the type of aeroplane concerned. 3.2 Landing weight charts which enable compliance with this Order are available on application to CASA. Instructions for the use of these charts are provided at Appendix 2.
