substitute
(ba) for aeroplanes with maximum take-off weight in excess of 5 700 kg, a weight that will permit compliance with the obstacle clearance requirements mentioned in paragraph 7.5 and subsection 12 for take-off from a dry runway (whether it is dry or not) and taking into account either wind conditions, ambient temperature and aerodrome elevation, or wind conditions and approved declared conditions;
[7]        Subsection 11
substitute
11        Landing distance required
     11.1     When determining the maximum weight for take-off of a jet-engined aeroplane of maximum take-off weight greater than 5 700 kg for the purpose of subparagraph 4.1 (d), the landing distance required is:
(a)   for an aeroplane engaged in regular public transport operations when the appropriate weather reports and forecasts, or a combination, indicate that the runways will be dry at the estimated time of arrival, or in charter operations — 1.67 times the distance required to bring the aeroplane to a stop on a dry runway; or
(b)   for an aeroplane engaged in regular public transport operations when the appropriate weather reports and forecasts, or a combination, indicate that the runways may be wet at the estimated time of arrival:
             (i)  1.92 times the distance required to bring the aeroplane to a stop on a dry runway; or
            (ii)  the distance set out in the flight manual or operations manual for operations conducted on wet runways.
     11.2     When determining the maximum weight for landing of a jet-engined aeroplane of maximum take-off weight greater than 5 700 kg for the purpose of subparagraph 5.1 (a), the landing distance required is 1.67 times the distance required to bring the aeroplane to a stop on a dry runway or, if actual landing distance data is supplied by the aircraft’s type certificate holder, 1.15 times the actual landing distance.
Note   Subparagraph 4.1 (d) refers to determining the permissible landing weight before take-off and subparagraph 5.1 (a) refers to re-assessing the permissible landing weight after take-off.
     11.3     For subparagraphs 4.1 (d) and 5.1 (a), when determining the maximum weight for take-off and landing, respectively, of a jet-engined aeroplane of maximum take-off weight not greater than 5 700 kg engaged in regular public transport operations, the landing distance required is 1.43 times the distance required to bring the aeroplane to a stop on a dry runway.
     11.4     When determining the maximum weight for take-off of a propeller-driven aeroplane for the purpose of subparagraph 4.1 (d), the landing distance required in regular public transport operations and charter operations is:
(a)   when the appropriate weather reports and forecasts, or a combination, indicate that the runways will be dry at the estimated time of arrival — 1.43 times the distance required to bring the aeroplane to a stop on a dry runway; or
(b)   when the appropriate weather reports and forecasts, or a combination, indicate that the runways may be wet at the estimated time of arrival:
             (i)  for a landing at a destination aerodrome — 1.67 times the distance required to bring the aeroplane to a stop on a dry runway; or
            (ii)  for a landing at an alternate aerodrome — 1.43 times the distance required to bring the aeroplane to a stop on a dry runway.
     11.5     When determining the maximum weight for landing of a propeller-driven aeroplane for subparagraph 5.1 (a), the landing distance required in regular public transport operations and charter operations is 1.43 times the distance required to bring the aeroplane to a stop on a dry runway.
     11.6     Subject to paragraph 11.8, the distance required to bring the aeroplane to a stop on a dry runway must be the horizontal distance necessary to land and come to a complete stop from a point 50 feet above the landing surface using information set out in the flight manual.
     11.7     Subject to paragraph 11.8, for a landing on a contaminated runway, the landing distance required is:
(a)   the distance set out in the flight manual or the operations manual for operations conducted on contaminated runways; or
(b)   the distance approved by CASA for operations conducted on runways covered by slush, snow or a depth of water; or
(c)   if actual landing distance data is supplied by the holder of the aircraft’s type certificate — 1.15 times the actual landing distance.
     11.8     For subparagraph 4.1 (d) and paragraph 5.1, an aeroplane engaged in private operations or aerial work operations, or a jet-engined aeroplane of maximum take-off weight not greater than 5 700 kg engaged in charter operations, must be operated so that compliance with the landing requirements is demonstrated using data set out in the flight manual or the manufacturer’s data manual.
Note   The data contained in some manufacturers’ data manuals is unfactored and makes no allowance for degraded aircraft performance.
     11.9     Paragraphs 11.2, 11.3, 11.5, 11.7 and 11.8 do not apply in the case of an emergency.
[8]        Paragraph 12.1
omit all words after
For the purpose of meeting this requirement,
insert
the planned departure procedure may include a change of heading but, in that event, the change of heading must not be initiated before a point where the net flight path clears all obstacles by at least 50 feet and, for the duration of the turn, the net flight path must clear by at least 50 feet vertically all obstacles in the take-off area. The planned angle of bank must not exceed 15°, except that in an approved RNP operation the planned angle of bank must not exceed 25° subject to the aeroplane’s flight manual containing data that supports the planned angle of bank. The data must provide an increased take-off safety speed V2 when planning an angle of bank greater than 15°. It must also contain data to allow construction of the net flight path when using an increased take-off safety speed V2 and when planning to use an angle of bank greater than 15°.
 
[9]        Subparagraph 12.1.1 (b)
omit all words after
take-off distance available.
insert
If the aircraft is equipped and approved to conduct RF legs and any turns, and the departure procedures are constructed using ARINC 424 RF path terminators, then the lateral expansion of the take-off area may be discontinued when the perimeter of the take-off area reaches:
             (i)  RNP set equal to, or greater than, 0.5 — 900 metres either side of the defined flight path; or
            (ii)  RNP set equal to, or less than, 0.2 — 370 metres either side of the defined flight path; or
           (iii)  RNP set to more than 0.2 but less than 0.5 — a distance either side of the defined flight path derived by linear interpolation between 370 metres and 900 metres according to the RNP.
[10]     Paragraph 12A.5
omit all words after
an approved RNP operation,
insert
the expansion of the take-off area may be discontinued when the perimeter of the take-off area reaches:
(a)    if RNP is set equal to or greater than 0.5 — 900 metres on either side of the defined flight path; or
(b)   if RNP set to or less than 0.2 — 370 metres on either side of the defined flight path; or
(c)    if RNP is set to more than 0.2 but less than 0.5 — a distance on either of the defined flight path, derived by linear interpolation, between 370 metres and 900 metres according to RNP.
