What is the proper way to address ZAB Center when an IFR flight from the west is requesting arrival sequencing?

• A. ZAB Center, N123AB, IFR, inbound from the west.
• B. ZAB Center, N123AB, IFR, outbound from the west.
• C. N123AB, ZAB Center, inbound IFR from west.
• D. ZAB Center, N123AB, inbound from the east, IFR.

Answer: (A)

When initiating contact with a Center for arrival sequencing, you want to identify the facility you’re calling, who you are, your status, and your position or direction of approach. Saying “ZAB Center, N123AB, IFR, inbound from the west” does exactly that: you’re addressing Albuquerque Center, identifying your aircraft by registration, confirming you’re IFR, and indicating you are inbound from the west. This lets the controller quickly place you in the arrival sequence and coordinate with other traffic.

The other formulations misrepresent either the contact order or the situation. Starting with the aircraft ID instead of the center makes the call less clear to the controller. Saying you’re inbound from the east is simply the wrong direction for this scenario, and stating outbound from the west implies you’re leaving the area rather than arriving.
