may either sense a crash and operate automatically or be
manually activated. An ELT may be any of the following:
Automatic fmed ELT (ELT(AF)). An ELT which is
permanently attached to an aircraft.
Automatic portable ELT (ELTtAP)). An ELT which is
rigidly attached to an aircraft but readily removable from
the aircraft after a crash.
Automatically deployable ELT (ELT(AD)). An ELT which is
rigidly attached to an aircraft and deployed automatically
in response to a crash. Manual deployment is also
provided.
Survival ELT (ELT(S)). An ELT which is removable from an
aircraft, stowed so as to facilitate its ready use in an
emergency and activated by survivors. Automatic
activation may apply.
Flight crew member. A licensed crew member charged with
duties essential to the operation of an aircraft during flight
time.
Flight mnnual. A manual, associated with the certificate of
airworthiness, containing limitations within which the
aircraft is to be considered airworthy, and instructions and
information necessary to the flight crew members for the
safe operation of the aircraft.
Flight plan. Specified information provided to air traffic
services units, relative to an intended flight or portion of a
flight of an aircraft.
Flight recorder. Any type of recorder installed in the aircraft
for the purpose of complementing accidentlincident
investigation.
Flight time. The total time from the moment an aircraft first
moves under its own power for the purpose of taking off
until the moment4 comes to rest at the end of the flight.
Note.- Flight time as here defined is synonymous with the
tern "block to block" time or "chock to chock" time in
general usage which is measured from the time an aircrafi
moves from the loading poinr until it stops at the unloading
point.
General aviation operation. An aircraft operation other than a
commercial air transport operation or an aerial work
operation.
Instrument approach and landing operalzons. Instrument
approach and landing operations using instrument approach
procedures are classified as follows:
Non-precision approach and landing operations. An
instrument approach and landing which does not utilize
electronic glide path guidance.
Precision approach and landing operations. An instrument
approach and landing using precision azimuth and glide
path guidance with minima as determined by the category
of operation.
Categories of precision approach and landing operations:
Category I (CAT I) operation. A precision instrument
approach and landing with a decision height not lower
than 60 m (200 ft) and with either a visibility not less than
800 m or a runway visual range not less than 550 m.
Cutegory II (CAT II) operation. A precision instrument
approach and landing with a decision height lower than
60 m (200 ft), but not lower than 30 m (100 ft), and a
runway visual range not less than 350 m.
Category IIZA (CAT IIIA) operation. A precision instrument
approach and landing with:
a) a decision height lower than 30 m (100 ft) or no
decision height; and
b) a runway visual range not less than 200 m.
Category IIIB (CAT IIIB) operation. A precision instrument
approach and landing with:
a) a decision height lower than 15 m (50 ft) or no
decision height; and
b) a runway visual range less than 200 m but not less
than 50 m.
Category ZZZC (CATIIIC) operation. A precision instrument
approach and landing with no decision height and no
runway visual range limitations.
Note.- Where decision height (DH) and runway visual
range (RVR) fall into diflerent categories of operation, the
instrument approach and landing operation would be
conducted in accordnnce with the requirements of the most
demanding category (e.g. an operation with a DH in the range
of CAT IIIA but with an RVR in the range of CAT IIIB would
be considered a CAT ZZZB operation or an operation with a
DH in the range of CAT II but with an RVR in the range of
CAT I would be considered a CAT 11 operation).
Instrument meteorological conditions (IMC). Meteorological
conditions expressed in terms of visibility, distance from
cloud, and ceiling*, less than the minima specified for
visual meteorological conditions.
Note.- The specified minima for visual meteorologicdl
conditions are contained in Chapter 4 of Annex 2.
*As defined in Annex 2.
Chapter 1 Annex 6 - Operation of Aircmft
Meteorological information. Meteorological report, analysis,
forecast, and any other statement relating to existing or
expected meteorological conditions.
