Operations — ZME Center

Air traffic personnel must comply with separation standards and procedures in FAA JO 7110.65, local directives, and letters of agreement to maintain a safe and efficient operation.

All airspace delegation maps, definitions, and coordination requirements are outlined in applicable letters of agreement and/or this policy.

DirectionRequired Altitude
Northbound (000°–179°)Altitude appropriate for 000–179°
Southbound (180°–359°)Altitude appropriate for 180–359°

Exception: Memphis arrivals on the SQS transition of the MARVELL or HOBRK STARs, or direct routes overlying these routes, need not be coordinated for direction-of-flight altitude between Sector 66 and Sector 15.

Intra-Facility Coordination of Altitude Information

Section titled “Intra-Facility Coordination of Altitude Information”

When making a radar handoff, point-out, or issuing traffic restrictions, automated means may relay altitude information in lieu of verbal means, provided:

  1. Aircraft will be at, climbing to, or descending to the altitude displayed in the full data block. Aircraft with a pilot’s discretion climb or descent must be verbally coordinated (except as specified in AITs).

  2. For aircraft changing stratums, controllers must clear aircraft to the lowest or highest altitude in their jurisdiction (weather/traffic permitting), coordinate with adjacent sectors, and transfer the flight for climb/descent.

  3. Transfer of Communications releases an aircraft established at or descending to the bottom of a stratum for pilot’s discretion descent, unless otherwise coordinated.

  4. When the receiving controller accepts a handoff, this means:

    • Climbing aircraft: Receiving controller must clear to an altitude in their stratum on initial contact, or verbally coordinate before accepting.
    • Descending aircraft: Receiving controller must clear to an altitude in their stratum when within lateral confines of their airspace, or verbally coordinate before accepting.
    • If, after accepting, the receiving controller delays climb/descent, they must immediately advise the transferring controller. The transferring controller remains responsible for coordination within their stratum until complete.
