Subject: **Comments from ICAO HQ on Proposal for Amendment of Regional
Supplementary Procedures -- Doc 7030/4**

> **(Serial No. APAC-S 03/10 -- MID/ASIA/PAC RAC)**

This is in reference to the proposal for amendment of the *Regional
Supplementary Procedures* (SUPPS, Doc 7030) regarding the lost
communication procedures for oceanic airspace. New Zealand requested
clarification as to the relationship between this proposal for amendment
and the current SUPPS. Based on the request, Director of Air Navigation
Bureau, ICAO, reviewed the proposal for amendment and has commented as
attached herewith.

New Zealand also recommends that in light of the recent *Procedures for
Air Navigation Services -- Air Traffic Management* (PANS-ATM, Doc 4444),
the offset distance for communication failure in the proposal for
amendment be aligned with the offset distance in the PANS-ATM in-flight
contingency procedures. You may recall that the Regional Office
coordinated with the States concerned and the States agreed that the
offset distance be changed to 15 NM from 10 NM.

Please draw your attention to the HQ's statement that PANS-ATM requires
that separation shall be maintained based on the assumption that the
aircraft will follow the established procedures, including the option to
adjust level and speed in accordance with the filed flight plan. ICAO HQ
understands that the proposal for amendment, however, stated that ATC
shall protect the aircraft's "last assigned route and level" and that
only essential traffic information needs to be provided with respect to
potential changes to level and speed by the aircraft.

Further, ICAO HQ is of view that the procedures for air-ground
communication failure are a separate set of procedures from those for
in-flight contingencies in oceanic airspace. Therefore, the proposal to
incorporate the offset for air-ground communication failure would change
the way we have traditionally dealt with communications failure.

In light of the foregoing, you may wish to discuss this matter at the
Informal Pacific ATC Coordinating Group and the Informal South Pacific
ATC Coordination Group, and align the proposal for amendment to the
PANS-ATM incorporating Amendment 4 and the SUPPS.

Regards,

I wish to refer to your memorandum dated 28 October 2005, reference T
3/03.10: AP-ATM0414, concerning the results of the circulation amongst
States and international organizations of the above proposal for the
amendment of the *Regional Supplementary Procedures* (SUPPs, Doc 7030).

Of particular interest were the issues raised by New Zealand in their
letter dated 30 September 2005. In this letter, New Zealand requests
clarification as to the relationship between this SUPPs amendment
concerning air-ground communications procedures and the special
procedures for in-flight contingencies contained in the current SUPPs,
but more recently incorporated into the *Procedures for Air Navigation
Services --- Air Traffic Management* (PANS-ATM, Doc 4444). New Zealand
also recommends that in light of the recent PANS-ATM amendment
(Amendment 4, applicable 24 November 2005), the offset distance for
communications failure in the SUPPs amendment be aligned with the offset
distance in the PANS-ATM in-flight contingency procedures.

New Zealand has highlighted a conflict between the SUPPs amendment
proposal and the PANS-ATM. Paragraph 15.3.3 of the PANS-ATM requires
that, in the event an aircraft fails to indicate that it is able to
receive and acknowledge transmissions, separation shall be maintained,
based on the assumption that the aircraft will follow a variety of
procedures, including the option to adjust level and speed in accordance
with the filed flight plan. Paragraphs 15.3.4 and 15.3.10 qualify the
procedures in paragraph 15.3.3 to the extent that separation would still
be maintained but possibly based on a different set of assumptions
and/or procedures. The SUPPs amendment, however, states that ATC shall
"protect the aircraft's last assigned route and level" and that only
essential traffic information needs to be provided with respect to
potential changes to level and speed by the aircraft affected by the
communications failure. The similarity between the wording of the SUPPs
amendment and PANS-ATM provisions concerned with special procedures for
in-flight contingencies in oceanic airspace, and the fact that the SUPPs
amendment, as proposed, indicated a subparagraph within the section
dealing with in-flight contingencies in oceanic procedures, may have
created confusion. While the text may seem similar, air-ground
communication failure procedures have never been considered part of
special procedures for in-flight contingencies in oceanic airspace. The
circumstances of the former are dealt with in PANS-ATM, paragraph 15.3
whilst the circumstances of the latter are, in general terms, listed in
PANS-ATM, paragraph 15.2.1.1. Similarly, the two subjects are dealt with
quite separately in the NAT/RAC SUPPs.

It is essential that, before we proceed any further, we reconcile the
amendment of the SUPPs with the PANS‑ATM, paragraphs 15.2 and 15.3. This
may be accomplished by aligning amendment proposal APAC-S 03/10 with the
PANS-ATM, paragraph 15.3, or amending PANS-ATM, paragraph 15.3. The
former might involve allowing for the offset but continue to maintain
standard separation. This, in itself, seems problematic acknowledging
that an offset might entail an alternative separation being established
with adjacent tracks that otherwise would not have been necessary had
the aircraft remained on track. The latter might involve allowing the
option of treating communications failure in oceanic airspace as an
in-flight contingency, along the lines of PANS‑ATM, paragraph 15.2.
This, of course, would signal a major change in the way we have
traditionally dealt with communications failure.

You may wish to consult with New Zealand and other proposing States, in
light of the foregoing, with a view to determining how best to avoid a
conflict with PANS-ATM provisions.
