Aerodrome Phraseology for Helicopters
3.1
Introduction
3.1.1
Rotary-wing flight characteristics mean that helicopter operations at aerodromes can
differ significantly from fixed-wing operations. This section describes standard
phraseology and procedures to address the different requirements for helicopter
lifting, taxiing, taking-off and landing (including the approach and departure phases),
particularly at aerodromes where rotary-wing and fixed-wing operations are
integrated.
3.1.2
Standard phraseology should be used in all situations for which it is specified. When
standardised phraseology cannot serve an intended transmission, plain language
should be used. The use of plain language may further assist when describing rotary-
wing aircraft manoeuvres. Care should be exercised to ensure that all parties involved
achieve clear understanding.
3.1.3
The phraseology described in this section is intended for general use. However, the
examples of taxiing phraseology describe communications specific to aerodromes at
which ATC or AFIS is provided. Phraseology examples for take-off and landing are
specific to communications at aerodromes with ATC.
3.2
Helicopter Callsigns
3.2.1
Aircraft callsigns to be used are described in Chapter 2 paragraph 1.8. Provision is
made for the name of the aircraft manufacturer, or the aircraft model, to be used
before the aircraft registration (in full or abbreviated form). If considered appropriate,
the pilot or ATSU may replace manufacturer’s name or aircraft model with the term
‘Helicopter’ where this may benefit the ATSU or other aircraft (see phraseology
examples paragraphs 3.8.5 and 3.8.6).
3.3
Helicopter Phraseology for Taxiing
3.3.1
These procedures are for helicopters taxiing for departure, or after landing, or for
general manouevring on the aerodrome. Phraseology and procedures for specific
manouevring on the aerodrome, for example for training purposes, should be
described in local procedures.
3.3.2
The term 'LIFT' shall describe a manoeuvre where the helicopter gets airborne and
enters a 'HOVER'.
3.3.3
'HOVER' describes a manoeuvre where the helicopter holds position whilst airborne
in ground effect, waiting to proceed. Hover allows spot/axial turns (i.e. about the
central axis of the helicopter). When required, further instructions should
subsequently be transmitted to permit the helicopter to proceed.
3.3.4
The term 'AIR TAXI' shall be used when it is necessary for a helicopter to proceed at
a slow speed above the surface, normally below 20 knots and in ground effect (ICAO).
3.3.5
The instruction 'GROUND TAXI' shall be used for the movement of a helicopter, in
contact with the surface of the aerodrome, under its own power. This could be
required for a helicopter fitted with wheels, to reduce rotor downwash (ICAO).
