Feeder View vs Runway View

Why there are two views

  • Feeder view is centered on via-fix streams, and is most relevant for Area Controllers not covering the TMA.
    • In Feeder view the Aircraft is attached to the timeline tape at its calculated EAT.
  • Runway view is centered on the runway and landing sequence, and is most relevant for Controllers covering the TMA.
    • In Runway view the Aircraft is attached to the timeline tape at its calculated PLT.
  • This view choice is independent of EAT:AR versus EAT:LT.
    • Both can show overlapping aircraft data, but the operational meaning of ordering and actions differs.

Side-by-side table

Topic Feeder View Runway View
Main question answered How is each via-fix stream flowing? What is the landing order and timeline?
Natural operational fit Area-controller or upstream feeding picture TMA or runway-side planning picture
Ordering focus Aircraft grouped and ordered by via-fix stream Aircraft ordered by the global landing sequence
Via-fix deselection Hides or dims that via-fix stream depending on layout/config Filters visibility or context, but does not mean the global landing sequence stops existing
Advance 1 effect Moves relative to the previous eligible aircraft in that via-fix stream Moves relative to the previous eligible aircraft in the global landing sequence
Resequence effect Releases the aircraft back into normal stream planning Releases the aircraft back into normal landing timeline planning
Best use Monitoring feeder balance and stream picture Managing the runway-side landing picture

Via-fix menu behaviour

  • In layouts with hideDeselectedViaFixes: true, deselected via-fix aircraft are hidden from that layout.
  • In layouts without that setting, deselected via-fix aircraft remain visible but are dimmed.
  • This is a display-only layout behavior. It does not change sequencing policy, EAT mode, ETA mode, or FMR authority.
  • In feeder layouts, deselection is primarily a stream visibility tool.
  • In runway layouts, deselection is still a display/filtering aid. The runway and landing sequence remain global even if one stream is hidden in that layout.

Advance 1 difference

  • In feeder view, Advance 1 is stream-relative.
  • In runway view, Advance 1 is landing-sequence-relative and global.
  • This same distinction is repeated on Aircraft Actions.
  • Choose feeder or runway view according to the operational role and picture you need.
    • In operational terms, feeder view usually matches the area-controller or upstream feeding picture, while runway view usually matches the TMA or runway-side picture.
  • That choice is separate from EAT:AR versus EAT:LT.
  • For current normal operations, EAT:LT is still the preferred engine mode.
  • Use feeder view to understand or troubleshoot via-fix stream balance.
  • Use runway view when the landing-order picture is the more important one to manage.
