MTOW means maximum take-off weight.
TAWS means terrain awareness and warning system.
TAWS-Class A has the meaning given by the CASR Dictionary.
TAWS-Class B has the meaning given by the CASR Dictionary.
TAWS-Class B+ means a TAWS that:
(a) is a TAWS-Class B; and
(b) includes a colour terrain display that meets the following requirements:
           (i) the displayed terrain information must be depicted relative to the aeroplane's position such that the pilot can estimate the relative bearing to the terrain of interest;
           (ii) the displayed terrain information must be depicted relative to the aeroplane's position such that the pilot may estimate the distance to the terrain of interest;
           (iii) the displayed terrain information depicted must be oriented to either the heading or the track of the aeroplane and may include an additional selectable north-up orientation format;
           (iv) variations in terrain elevation must be depicted relative to the aeroplane's current or projected elevation (above and below) and be visually distinct, except that terrain that is more than 2 000 feet below the aeroplane's elevation may be excluded;
           (v) terrain that generates alerts must be displayed in a manner that distinguishes it from non-hazardous terrain, consistent with the caution and warning alert level relevant to the TAWS Class B equipment.
       (2) This section applies to the operator of an aeroplane for a flight that is a Subpart 121.Z operation (a relevant flight), but only if the aeroplane:
(a) has a maximum operational passenger seat configuration of 13 or less; and
(b) is a turbine-engine aeroplane; and
(c) has an MTOW of 5 700 kg or less.
       (3) For a relevant flight in the aeroplane, the operator is exempted from compliance with:
(a) subregulation 121.775(1); and
(b) subregulation 121.775(3), to the extent that it applies to subregulation 121.775(1).
       (4) It is a condition of the exemptions in subsection (3) that the requirement in subsection (5) is complied with for the relevant flight.
       (5) Before the relevant flight, the aeroplane must be fitted with one of the following:
(a) a TAWS-Class B+; or
(b) a TAWS-Class A.
       (6) A TAWS mentioned in subsection (5) must be operative at the beginning of the relevant flight unless:
(a) the flight begins:
           (i) from an aerodrome with no facility for the TAWS to be repaired or replaced; and
           (ii) not more than 24 hours after the TAWS was first found to be inoperative; or
(b) the flight is:
           (i) operated under an authorised weather forecast that indicates the flight can be conducted in VMC by day when operating below the minimum heights stated in subregulations 91.265(2), 91.267(2) and 91.305(2) (the relevant minimum heights); and
           (ii) conducted in VMC by day below the relevant minimum
