Regulation OTAR Part 135 - CAT - Helicopters and Small Aeroplanes

(b) where provided by the aircraft manufacturer or other source, contained in an equivalent
document; and
(c) available to all flight crew or other persons responsible for flight planning or aircraft dispatch.
OTAR.135.520 Runway friction coefficient
The operator shall ensure that where performance data has been determined using measured coefficient
of runway friction, the pilot-in-command complies with a procedure that correlates the measured coefficient
of runway friction and the effective braking coefficient of friction of that aeroplane type, over the required
speed range for the existing runway conditions.
OTAR.135.525 Runway surface conditions
The operator shall ensure that:
(a) runway surface conditions have been taken account of in any performance calculations made;
and
(b) runway surface conditions do not preclude a safe aircraft departure.

OTAR.135.530 Wet and contaminated runway surfaces
The operator shall ensure that where it is necessary for a take-off to be made on a runway contaminated
with water, slush, snow or ice account is taken of:
(a) the runway overrun area; and
(b) local wind conditions, including any element of tailwind or crosswind; and
(c) height of any snow banks adjacent to the runway.

OTAR.135.535 Runway factors
The operator shall ensure that where a runway is not a paved, dry, flat surface appropriate performance
factors are applied to any calculation of distance required for take off or landing.
OTAR.135.540 Grass runways
The operator shall ensure that:
(a) only performance data provided for grass runways under the specified conditions for the surface
is used. Where no specification is made, the performance data shall only be used if:
(1) the grass is less than 8 inches (20 cm) high; and
(2) soil conditions are firm, such that there may be wheel impressions in the soil but no
rutting.
(b) any damp grass surface is considered to be wet for the purpose of applying performance
factors.
OTAR.135.545 Loss of runway length
The operator shall, when calculating distance available for take off, take account of any length of the runway
which will necessarily be used for lining up the aircraft in the direction of take-off.
OTAR.135.550 Short landings – aeroplanes
An operator needing to use Short Landing Operations (where the distance used for the calculation of
permitted landing mass may include the usable length of the declared safe area) shall require an approval
by the Governor. (See Appendix 1 to 135.550)
OTAR.135.550 APP1 Short landing operations
(a) For the purpose of short landing operations, thedistance used for the calculation of the permitted
landing mass may consist of the usable length of the declared safe area plus the declared
landing distance available. The Govenor may approve such operations in accordance with the
following criteria:
(1) Demonstration of the need for short landing operations. There must be a clear public
interest and operational necessity for the operation, either due to the remoteness of the
airport or to physical limitations relating to extending the runway.
(2) Aeroplane and operational criteria:
(i) Short landing operations will only be approved for aeroplanes where the
vertical distance between the path of the pilot’s eye and the path of the lowest
part of the wheels, with the aeroplane established on the normal glide path,
does not exceed 3 m.
(ii) When establishing aerodrome operating minima the visibility/RVR must not
be less than 1,500 m. In addition, wind limitations must be specified in the
operations manual.
(iii) Minimum pilot experience, training requirements and special aerodrome
familiarisation must be specified for such operations in the operations
manual.
(3) It is assumed that the crossing height over the beginning of the usable length of the
declared safe area shall not be less than 50 ft.
(4) Additional criteria: The Governor may impose such additional conditions as are
deemed necessary for a safe operation taking into account the aeroplane type
characteristics, orographic characteristics in the approach area, available approach
aids and missed approach/baulked landing considerations. Such additional conditions
may be, for instance, the requirement for VASI/PAPI -type visual slope indicator system.
