    The display of Mode C targets and limited data blocks is necessary for application of Merging Target Procedures. Sectors must ensure the display of Mode C targets and data blocks by entering appropriate altitude limits and display filters to include, as a minimum, the altitude stratum of the sector plus:

    1. 1,200 feet above the highest and below the lowest altitude or flight level of the sector where 1,000 feet vertical separation is applicable; and
    2. 2,200 feet above the highest and below the lowest flight level of the sector where 2,000 feet vertical separation is applicable.
    • NOTE:
    • 1. The data block, for purposes of this paragraph, must contain the Mode C altitude and call sign or beacon code at a minimum.
    • 2. Exception to these requirements may be authorized for specific altitudes in certain ARTCC sectors if defined in appropriate facility directives and approved by the En Route and Oceanic Operations Area Director.
