but no later than one (1) minute after receiving that instruction from ATC, unless that instruction
specifies a later time or place. ATC may require that an assigned level must be reached by a specific
time, distance or place. If a pilot in command doubts that the requirement can be met, ATC must be
advised immediately.
A requirement to report at a time or place given in the same clearance as a descent/climb instruction
does not require the new level to be reached by the specified time or place.
The pilot in command of an aircraft operating in controlled airspace must report:
• when the aircraft has left a level at which level flight has been conducted in the course of a climb,
cruise or descent; and
• when the aircraft leaves a level for which ATC has requested a report.
ATC may provide vertical separation between two climbing aircraft, not otherwise
separated, by means of a step-climb. Pilots in command, who are subjected to a step-climb,
must adopt the following procedure:
• The pilot in command of the lower aircraft must report approaching each assigned level in the
sequence.
• The pilot in command of the higher aircraft, on hearing the lower aircraft report approaching each
assigned level, must report the last vacated level.
Step-descents are the reverse of the above paragraphs.
ATC may specify a rate of climb or descent. Other considerations are as follows:
• The phrase “STANDARD RATE” when included in a clearance, specifies a rate of climb or descent of
not less than 500FT per minute, except that the last 1,000FT to an assigned level must be made at
500FT per minute.
• In the case of a step-climb or descent, the specified rate will be applicable to all level clearances issued
in the course of the step climb or descent. If unable to comply with the prescribed rate, the pilot in
command must advise ATC.
Cruise climb requirements will be accommodated provided that other aircraft are not denied the use of
that airspace contained between the reporting points for which the climb is expected to take place.

ENGINE START, PUSH-BACK AND TAXI
ENGINE START
The pilot in command of an aircraft must request approval to start engines when the
requirement is notified by ATIS, NOTAM, AIP Supplement, ATC or listed in ERSA.
PUSH BACK
The pilot in command must obtain an approval to push back where this manoeuvre is
necessary prior to taxiing. Information about other aircraft moving on the same apron
will be provided by the apron service.
TAXI CLEARANCE
When operating from a controlled aerodrome where ATIS is in operation a pilot in
command must obtain the ATIS prior to taxi, and advise ATC of the ATIS code when
requesting taxi clearance.
The pilot in command must obtain a taxi clearance either prior to moving on the
manoeuvring area, or in the case of the above paragraph, at the completion of the
push-back manoeuvre.
The taxi clearance regulates entrance to, and movement on, the taxiways. Avoidance
of collision on apron areas is a joint responsibility of the pilot in command and any
assisting company ground personnel. Information about other aircraft moving on the
same apron area will be provided by the ATC. (where it exists as a discrete service)
Subject to the following paragraphs, a pilot in command for whom a runway
has been nominated for take-off must regard the taxi clearance limit to be:
• for piston-engined aircraft - the holding bay, if provided, otherwise the holding point
for the runway; and
• for turbine-engine aircraft or aircraft which have reported “READY” before reaching
the holding bay - the holding point for the runway.
A taxi instruction which contains taxi limit beyond a runway must include a “CROSS
RUNWAY (number)” instruction to cross that runway. When an aircraft is required to
hold short of a runway intersecting the taxi route, ATC will issue a taxi instruction limit
of the holding point associated with the intersecting runway.
An aircraft which has been issued with a taxi instruction limit of the holding point of a
runway intersecting the taxi route, or which has been issued with an instruction to
“HOLD SHORT” of that runway must subsequently be issued with an instruction to
