(e) identification of suitable parking area;
(f) maintaining lookout and right-of-way rules and complying with ATC or marshalling
instructions when applicable;
(g) avoidance of adverse effect of propeller slipstream or jet wash on other aeroplanes,
aerodrome facilities and personnel;
(h) inspection of taxi path when surface conditions are obscured;
(i) communication with others when controlling an aeroplane on the ground;
(j) interpretation of operational instructions;
(k) reporting of any problem that may occur while taxiing an aeroplane; and
(l) adapting the taxi speed in accordance with prevailing aerodrome, traffic, surface and
weather conditions.
NCO.GEN.120 Rotor engagement — helicopters
A helicopter rotor shall only be turned under power for the purpose of flight with a qualified pilot at the
controls.
NCO.GEN.120 GM1 Rotor engagement
INTENT OF THE RULE
(a) The following two situations where it is allowed to turn the rotor under power should be
distinguished:
(1) for the purpose of flight, this is described in the implementing rule;
(2) for maintenance purposes.
(b) Rotor engagement for the purpose of flight: it should be noted that the pilot should not
leave the control when the rotors are turning. For example, the pilot is not allowed to get
out of the aircraft in order to welcome passengers and adjust their seat belts with the
rotors turning.
(c) Rotor engagement for the purpose of maintenance: the implementing rule, however,
should not prevent ground runs being conducted by qualified personnel other than pilots
for maintenance purposes.
The following conditions should be applied:
(1) The operator should ensure that the qualification of personnel, other than pilots,
who are authorised to conduct maintenance runs is described in the appropriate
manual.
(2) Ground runs should not include taxiing the helicopter.
(3) There should be no passengers on board.
(4) Maintenance runs should not include collective increase or auto pilot engagement
(risk of ground resonance).
NCO.GEN.125 Portable electronic devices
The pilot-in-command shall not permit any person to use a portable electronic device (PED) on board
an aircraft, including an electronic flight bag (EFB), that could adversely affect the performance of the
aircraft systems and equipment or the ability of the flight crew member to operate the aircraft.
NCO.GEN.125 AMC1 Portable electronic devices (PEDs)
ELECTRONIC FLIGHT BAGS (EFBS) — HARDWARE
(a) EFB viewable stowage
When a viewable stowage device is used, the pilotincommand should ensure that, if the
EFB moves or is separated from its stowage, or if the viewable stowage is unsecured
from the aircraft (as a result of turbulence, manoeuvring, or other action), it will not jam
flight controls, damage flight deck equipment, or injure any person on board.
The viewable stowage device should not be positioned in such a way that it obstructs
visual or physical access to aircraft controls and/or displays, flight crew ingress or
egress, or external vision. The design of the viewable stowage device should allow the
user easy access to any item of the EFB system, and notably to the EFB controls and a
clear view of the EFB display while in use.
(b) Cables
If cables are used to connect an EFB to an aircraft system, power source, or any other
equipment:
(1) the cables should not hang loosely in a way that compromises task performance
and safety; flight crew should be able to easily secure the cables out of the way
during operations (e.g. by using cable tether straps); and
(2) the cables should be of sufficient length so that they do not to obstruct the use of
any movable device on the flight deck.
NCO.GEN.125 AMC2 Portable electronic devices (PEDs)
ELECTRONIC FLIGHT BAGS (EFBS) — FUNCTIONS
(a) Familiarisation The pilot-in-command should familiarise himself or herself with the use of
the EFB hardware and its applications on the ground before using them in flight for the
first time. A user guide should be available for the pilot-in-command.
(b) Check before flight Before each flight, the pilot-in-command should perform the following
checks to ensure the continued safe operation of the EFB during the flight:
(1) general check of the EFB operation by switching it ON and checking that the
applications they intend to use in flight are adequately operative;
(2) check of the remaining available battery power, if applicable, to ensure the
availability of the EFB during the planned flight;
