Pursuant to subsection 5.9(2) of the Aeronautics Act and after having taken into account that the exemption is both in the public interest and is not likely to adversely affect aviation safety, I hereby exempt NAV CANADA, 77 Metcalfe Street, Ottawa, Ontario, K1P 5L6 and all air traffic controllers working for hire or reward for NAV CANADA at the Calgary International Airport, Alberta, Canada from the requirement of paragraph 6.3.1(b) of Chapter 3 of Standard 821 ‑ Canadian Domestic Air Traffic Control Separation Standards, made pursuant to paragraphs 801.01(2)(a) and 801.08(b) of the Canadian Aviation Regulations (CARs), subject to the following conditions.
The relevant provisions of the CARs and Standard 821 are reproduced in Appendix A.
The purpose of this exemption is to allow NAV CANADA air traffic controllers at the Calgary International Airport to authorize reduced angular divergence of air traffic control separation from 15 degrees or more to 10 degrees or more, as it pertains to simultaneous parallel instrument departure operations (SPID). The rationale for the reduction of angular divergence at Calgary International Airport is one of the elements of the overall noise abatement program at that Airport.
This exemption applies to NAV CANADA and its air traffic controllers at the Calgary International Airport when issuing air traffic control clearances or instructions, as it pertains to SPID, and only to aircraft departing from runways 17L and 17R.
This exemption is subject to the following conditions:
- NAV CANADA air traffic controllers shall assign, to both departing aircraft, tracks or, as appropriate, headings to ensure that the tracks diverge by 10 degrees or more immediately after take-off;
- NAV CANADA air traffic controllers may assign a heading to one aircraft and a track to another aircraft, provided drift correction is applied to the aircraft on the heading to ensure the required divergence;
- NAV CANADA air traffic controllers shall only apply 10 degrees or more divergence to aircraft departing from runways 17L and 17R at Calgary International Airport;
- NAV CANADA air traffic controllers shall radar identify both departing aircraft within one mile of the end of the runway used for take-off; and
- NAV CANADA air traffic controllers shall not clear or permit an aircraft to turn toward the departure path of the other aircraft, unless another form of separation has been achieved.
This exemption is in effect until the earliest of the following:
- August 31, 2019 at 23:59 (MDT);
- the date on which any condition set out in this exemption is breached; or
- the date on which this exemption is canceled in writing by the Minister where she is of the opinion that it is no longer in the public interest or it is likely to adversely affect aviation safety.
DATED at Ottawa, Ontario, this 27th of October, 2014, on behalf of the Minister of Transport.
