to be conducted; and
(3) weather minima must be specified and approved for each runway to be used with a
steep approach.
Consideration must be given to the following:
(i) the obstacle situation;
(ii) the type of glide path reference and runway guidance such as visual aids,
MLS, 3D–NAV, ILS, LLZ, VOR, NDB;
(iii) the minimum visual reference to be required at DH and MDA;
(iv) available airborne equipment;
(v) pilot qualification and special aerodrome familiarisation;
(vi) aeroplane flight manual limitations and procedures; and
(vii) missed approach criteria.

OTAR.135.560 Performance – mass limitation
The operator shall ensure that:
(a) the mass of the aeroplane at the start of the take-off; or in the event of in-flight replanning, at the
point from which the revised operational flight plan applies, is not greater than the mass at which
the requirements of the applicable Performance Class can be complied with for the planned
flight. Allowance shall be made for expected reductions in mass as the flight proceeds, and for
fuel jettisoning where applicable;
(b) in no case shall the mass at the start of take off exceed the maximum take off mass specified in
the flight manual for that pressure altitude appropriate to the aerodrome elevation and, if used as
a parameter to determine the maximum take off mass any other local atmospheric condition;
(c) in no case shall the estimated mass for the expected time of landing at the planned destination
aerodrome and at any destination alternate aerodrome, exceed the maximum landing mass
specified in the flight manual for the pressure altitude appropriate to the aerodrome elevation(s),
and if used as a parameter to determine the maximum landing mass, any other local
atmospheric condition; and
(d) the mass of the aeroplane at the time of take-off, or at the expected time of landing at the
destination and at any planned alternate does not exceed the maximum mass at which the
applicable noise certification has been granted unless otherwise authorised by the Governor.
OTAR.135.565 Applicability of performance classes – aeroplanes
Note: The technical descriptions relevant to each performance class are contained in Appendix E to OTAR
Part 91.
The operator shall ensure that:
(a) multi-engine aeroplanes powered by turbo-propeller engines with a maximum approved
passenger seating configuration of more than 9 and all multi-engine turbojet powered aeroplanes
are operated in accordance with Performance Class A;
(b) propeller driven aeroplanes with a maximum approved passenger seating configuration of 9
seats or fewer, and a MTOM of 5,700 kg or less are operated in accordance with Performance
Class B;
(c) where full compliance with these requirements cannot be shown due to specific design
characteristics, the operator shall apply approved performance standards that ensure a level of
safety equivalent to that of the appropriate Performance Class; and
(d) unless it is flying on a special VFR flight in a control zone, a single-engine aeroplane, or a two-
engine aeroplane which does not meet the climb performance of Appendix E4.040, shall not be
operated:
(1) in instrument meteorological conditions; or
(2) at night.

OTAR.135.570 Applicability of performance classes – helicopters
Note: The technical descriptions relevant to each performance class are contained in Appendix E to OTAR
Part 91.
The operator shall ensure that:
(a) helicopters which have a maximum approved passenger seating configuration of more than 19,
or helicopters operating to or from heliports in a congested hostile environment are operated in
Performance Class 1;
(b) helicopters which have a maximum approved passenger seating configuration of 19 or less but
more than 9 are operated in Performance Class 1 or 2;
(c) helicopters which have a maximum approved passenger seating configuration of 9 or less are
operated in Performance Class 1, 2 or 3;
(d) helicopters operated in Performance Classes 1 or 2 are certificated in Category A;
(e) helicopters operated in Performance Class 3 are certificated in Category B;
(f) operations in Performance Class 2 without an assured safe forced landing capability during the
take-off and landing phases shall only be conducted if the operator has been granted an approval
by the Governor in accordance with Appendix E8;
(g) helicopters operated in Performance Class 3 are not operated:
