Interface

Some screenshots in this guide were taken on an older ALB release. They still show the same main areas, but small label or spacing details may differ.

Main window

ALB is built around four working areas:

  1. The top button row for quick policy and display toggles
  2. The menu row for timelines, via-fixes, layout, peers, and older retained legacy surfaces
  3. The stats and arrival-planning block at the top left
  4. The timeline area containing the aircraft rows

Stats and arrival-planning block

The planning block overlaps the upper-left part of the timeline area.

ALB stats

The top line contains the airport-wide landing plan:

  • PLR is the planned landing rate
  • the actual landing figure shows recent achieved landing rate
  • the missed figure shows recent missed-approach activity

Each via-fix line then shows the stream-specific planning picture:

  • AR: current minutes between releases for that stream
  • Cp: capacity implied by the current AR
  • the via-fix name
  • near-term demand distribution
  • number of aircraft in hold
  • 15-minute buckets
  • TMA count

Lines showing ----- are separators or subtotal breaks from the configured timeline definition.

What is clickable here

  • Left-click PLR to decrease the planned landing rate by 1
  • Right-click PLR to increase the planned landing rate by 1
  • Left-click a stream AR to decrease the interval by 1 minute
  • Right-click a stream AR to increase the interval by 1 minute

In EAT:LT, AR is not the active planning driver. Visible AR values are legacy/context information, and AR adjustment is not the normal control method.

Timeline area

The timeline rows are the operational center of ALB.

  • Left-click an aircraft row to select it
  • When possible, that selection follows EuroScope ASEL behavior
  • If you select an aircraft elsewhere and it is relevant to the active timelines, ALB can highlight it in the list
  • Right-click an aircraft row to open the aircraft action menu
  • Whether ordering and sequence actions are stream-relative or global depends on the current feeder or runway layout

See Aircraft Actions for the right-click behavior. See Feeder View vs Runway View for the layout-specific meaning.

ELT and ETA in the display

Some layouts show landing-time style labels such as ELT, ELT-ES, or ELT-ALB.

  • ELT means estimated landing time
  • ELT-ES is the live EuroScope-style branch
  • ELT-ALB is the ALB-corrected branch when that branch is relevant

ELT-ALB may include ALB's configured orange timing before the aircraft is deep into terminal handling. In ALB documentation, orange timing means the configured route or STAR-based track miles from the via-fix or holding-fix area toward touchdown. It is a planning estimate used while the aircraft is still far enough out that route-based timing is useful.

At a practical level, ALB builds that estimate from the via-fix timing anchor plus a configured orange distance-to-land. It then converts that distance into time with a three-part descent model:

  • a higher-distance segment that assumes faster descent speeds
  • a TMA segment for the next part of the arrival
  • a final segment close to landing

The current baseline is roughly jet-like:

  • about 250 KIAS in the higher segment
  • about 180 KIAS in the TMA segment
  • about 145 KIAS on the final segment

When flight-plan performance data is available, ALB can refine those segment speeds for the specific aircraft. When upper-wind data is available, ALB can also let that wind shift the ground-speed side of the estimate.

Once the aircraft is inside terminal or post-via handling, ALB should not keep inventing a separate orange-based landing estimate. At that point the live EuroScope-style branch is normally the safer basis.

The top-row ETA:ES or ETA:ALB button controls which estimate branch ALB uses where that policy applies.

For the full config and tuning details, see Config File Reference.

Status line and peer awareness

The lower information area is used for ALB status text. It is where mode and communication health feedback appears, while the Peers menu gives you a compact airport-by-airport view of who else is connected.

In current ALB builds, the Peers view may also summarize the peer's EAT policy and ETA branch context in a compact form. It remains an informational surface, not the place where you change authority.

In current simplified control-bar layouts, Peers appears immediately after Layout.
