ANNEX 10 and
PANS-ATM
See UK AIP GEN 1.7
RECLEARED (ICAO) is only used in the
UK for route clearances and not for
vertical clearances.
The direction of vertical movement,
provided by CLIMB and DESCEND,
acts as a check in some
circumstances when a pilot
misinterprets a call not directed at
him/her.
Annex 10
See UK AIP GEN 1.7
The following method of acknowledging
receipt is not used in the UK.
'The callsign of the aircraft followed if
necessary by callsign of the
aeronautical station' (ICAO).
(CALLSIGN) ROGER is used in the UK.
The UK procedure is in accordance
with the examples in ICAO Doc
9432 (1990) Manual of
Radiotelephony, which are different
to those described in ICAO Annex
10 Aeronautical
Telecommunications.
PANS-ATM
See UK AIP GEN 1.7
Phraseology ‘CLEARED FOR ILS
APPROACH’ is used in the UK only for
self-positioned approaches.
For radar-positioned ILS approaches in
the UK, pilots will be instructed: 'When
established on the localiser, descend
on the glidepath...'
Due to procedure design and
airspace complexity, along with
lessons learned from flight safety
related incidents and occurrences,
the UK has elected to enhance
safety by adopting unambiguous
phraseology that includes a positive
descent instruction to ensure that
descent is initiated only when it is
safe to do so.
PANS-ATM
See UK AIP GEN 1.7
RVSM Phraseology
In the UK, pilots are not required to
report nonapproved (RVSM) status in all
requests for level changes and in all read-
backs of level changes (ICAO).
This procedure is considered too
cumbersome and not required as
the controller has a mechanism for
the status of the aircraft to be
reflected.
PANS-ATM
See UK AIP GEN 1.7
and 3.3.3
The ICAO phraseology for conditional
line-up clearance BIGJET 347, BEHIND
THE DC9 ON SHORT FINAL, LINE UP
BEHIND (ICAO) is not used.
In the UK the phrase BIGJET 347 AFTER
THE LANDING DC9 LINE UP is used.
AFTER is used instead of BEHIND
to describe more clearly 'sequential
following' rather than 'further back'.
The reiteration of the condition at
the end of the phrase is considered
to reduce the clarity of the
instruction.
PANS-ATM
See UK AIP GEN 1.7
In the UK an additional phrase, LAND
AFTER THE (Aircraft Type) is used.
This phrase may be used under
certain conditions and indicates that
a preceding aircraft is not clear of
the runway.
