ATSIN Number 48, issued 9 August 2004 advises providers of aerodrome air traffic control service, and providers of aerodrome flight information service of the introduction of new standardised phraseology for helicopter operations.

A review by carried out by the CAA identified that certain phraseology in use by helicopter pilots and air traffic service personnel could be interpreted differently. One example provided was the term 'lift', which could mean 'lift into a hover', or 'depart', depending on the aerodrome or the pilot.

ICAO defines some helicopter phraseology in Doc.4444 PANS-ATM, however the defined phraseology was considered inadequate to fully describe helicopter operations. A requirement was identified for a more complete set of standard terms.
Additionally, the need for appropriate phraseology to authorise movements not confined to the manoeuvring area, not in sight of the VCR, or unlit sites at night, was also recognised.

A small but comprehensive set of helicopter phraseology has therefore been determined. The principal aim of the new phraseology is to remove any potential source for misunderstanding in radiotelephony communications. Where ICAO terms and definitions do exist, these have been incorporated.

The new phraseology will be published in a Supplementary Instruction included with Amendment 63 to CAP493 , and CAP413 Edition 15, effective 1 September 2004.

The new phraseology (as set out for publication in CAP413) is reproduced as an appendix to the ATSIN.

I think the only problems occur at airports where helicopters are not usually seen - ATC generally expect you to taxi following FW procedures and go to the runway for departure; then when you ask to lift and depart from your present position instead they agree with 'clear lift and depart from present position etc' which could be construed as a take off clearance but should really lead inot the 'ready for departure', 'clear take off' exchange.

Can anybody tell me why being unable to see a Video Cassette Recorder should affect the phraseology ? :}

I really fail to see why phrases like "Taxi instructions", "Request take off clearance", "clear take off" etc are inadequate. They have been used for years without a problem. The only difference with helicopter operations is that a helicopter can "depart direct on track" or "request take off present position to the South, south west or whatever".

Is this all about someone trying to justify their position in life?

'Request Take Off' should never be used by any aircraft. It can lead to confusion: the term 'take off' is only used in a clearance and the subsequent acknowledgement.
