Annex 11, 2.6.
Controlledflight. Any flight which is subject to an air traffic
control clearance.
Controller-pilot data link communications (CPDLC). A means
of communication between controller and pilot, using data
link for ATC communications.
Control zone. A controlled airspace extending upwards from
the surface of the earth to a specified upper limit.
Cruise climb. An aeroplane cruising technique resulting in a
net increase in altitude as the aeroplane mass decreases.
Cruising level. A level maintained during a significant portion
of a flight.
Currentflightplan. The flight plan, including changes, if any,
brought about by subsequent clearances.
Danger area. An airspace of defined dimensions within which
activities dangerous to the flight of aircraft may exist at
specified times.
Data link communications. A form of communication intended
for the exchange of messages via a data link.
Estimated off-block time. The estimated time at which the aircraft
will commence movement associated with departure.
Estimated time of arrival. For IFR flights, the time at which
it is estimated that the aircraft will arrive over that designated
point, defined by reference to navigation aids, from
which it is intended that an instrument approach procedure
will be commenced, or, if no navigation aid is associated
with the aerodrome, the time at which the aircraft will
arrive over the aerodrome. For VFR flights, the time at
' which it is estimated that the aircraft will arrive over the
aerodrome.
Expected approach time. The time at which ATC expects tha
an arriving aircraft, following a delay, will leave the holdin
fuc to complete its approach for a landing.
Note.- The actual time of leaving the holding fix u
depend upon the approach clearance.
Annex 2 - Rules of the Air Chapter 1
Filedflightplan. The flight plan as filed with an ATS unit by
the pilot or a designated representative, without any
subsequent changes.
Flight crew member. A licensed crew member charged with
duties essential to the operation of an aircraft during a flight
duty period.
Flight information centre. A unit established to provide flight
information service and alerting service.
Flight information region. An airspace of defined dimensions
within which flight information service and alerting service
are provided.
Flight information service. A service provided for the purpose
of giving advice and information usefil for the safe and
efficient conduct of flights.
Flight level. A surface of constant atmospheric pressure which
is related to a specific pressure datum, 1 013.2 hectopascals
(hPa), and is separated from other such surfaces by specific
pressure intervals.
Note I.- A pressure type altimeter calibrated in accordance
with the Standard Atmosphere:
a) when set to a QNH altimeter setting, will indicate altitude;
b) when set to a QFE altimeter setting, will indicate height
above the QFE reference datum;
c) when set to a pressure of 1 013.2 hPa, may be used to
indicate flight levels.
Note 2.- The terms "height" and "altitude", used in
Note I above, indicate altimetric rather than geometric heights
and altitudes.
Flight plan. Specified information provided to air traffic
services units, relative to an intended flight or portion of a
flight of an aircraft.
Flight visibility. The visibility forward from the cockpit of an
aircraft in flight.
Ground visibility. The visibility at an aerodrome as reported
by an accredited observer or by automatic systems.
Heading. The direction in which the longitudinal axis of an
aircraft is pointed, usually expressed in degrees from North
(true, magnetic, compass or grid).
Height. The vertical distance of a level, a point or an object
considered as a point, measured from a specified datum.
IFR. The symbol used to designate the instrument flight rules.
ZFRflighi. A flight conducted in accordance with the instrument
flight rules.
ZMC. The symbol used to designate instrument meteorological
conditions.
Instrument approach procedure. A series of predetermined
manoeuvres by reference to flight instruments with specified
protection from obstacles from the initial approach fix,
or where applicable, from the beginning of a defined arrival
route to a point from which a landing can be completed and
thereafter, if a landing is not completed, to a position at
which holding or en-route obstacle clearance criteria apply.
Instrument approach procedures are classified as follows:
Non-precision approach (NPA) procedure. An instrument
