Un-Announced Speed Changes


Mach Speed Variation

• The previous data was collected for the first 10 days of the month and now we conduct spot checks.

• De-identifying the data has caused airlines to request their speed data for review.

• A change in the welcome message seems to have triggered more compliance with speed change updates/requests.


Speed Change NOTAM • A1445/15 - ATTN ALL AIRCREWS-NEW PROCEDURAL

REQUIREMENT FOR FLIGHTS OPERATING IN OAKLAND OCEANIC CONTROL AREA (KZAK). IN ORDER TO SUPPORT COST INDEX OR ECON SPEEDS AND MAINTAIN ATC SEPARATION SPACING AIRCREWS ARE REQUIRED TO USE THE FOLLOWING PROCEDURES IN THE KZAK FIR. A PILOT MUST INFORM ATC VIA VOICE OR CPDLC EACH TIME THE CRUISING MACH NUMBER VARIES OR IS EXPECTED TO VARY BY A VALUE EQUAL TO OR GREATER THAN 0.02 MACH FROM:

• (1) THE MACH NUMBER AT FIR ENTRY; OR • (2) ANY SUBSEQUENT SPEED CHANGE NOTIFIED TO ATC IN

Conclusion• The data indicates that aircrews are not fully complying with

the procedure, however there has been significant improvement.

• Oakland will continue to work to raise pilots’ awareness and compliance with the procedure.

• The information is presented at local meetings and shared with airlines as requested.

• Hopefully by continuing this effort we will gain compliance and KZAK can continue to support Cost Index or Econ Speeds.

Tailored Arrivals


Tailored Arrivals• The Tailored arrival has been permanently

turn off and replaced with the PIRAT TWO arrival.

• PIRAT TWO is now being modified with a crossing restriction at PIRAT approximately 1 year out.
