Consolidation

Consolidation defines parent-child relationships between positions. When a child position is offline, calls route to its parent automatically.

What is Consolidation?

In ATC operations, when a controller goes offline, another controller often "picks up" their responsibilities. Consolidation in Landline mirrors this by automatically routing calls to the appropriate online position.

Example Hierarchy:

                    ABQ_CTR (root)
                       │
           ┌───────────┴───────────┐
           │                     │
        U90_APP               U90_DEP
           │
     ┌─────┴─────┐
     │          │
  TUS_TWR    TUS_GND

When TUS_TWR is offline:
  → Calls to TUS_TWR route to U90_APP (parent)

When both TUS_TWR and U90_APP are offline:
  → Calls to either route to ABQ_CTR (grandparent)

Understanding the Tree

Visual Elements

Setting Parent Relationships

Method 1: Drag and Drop

1. Click and hold the grip dots (⠿) next to a position
2. Drag over another position (potential parent)
3. The target highlights with a blue ring
4. Drop to set the parent relationship

Method 2: Context Menu

1. Right-click any position to open the context menu
2. Choose from:
   • Make root position - Remove parent, place at top level
   • Select parent position - Open a searchable modal to pick a parent

Method 3: Parent Selector Modal

When you select "Select parent position" from the context menu:

1. A modal opens with a searchable list of positions
2. Use the search box to filter by callsign or display name
3. Click a position to set it as the parent
4. Click "No parent (root position)" to remove the parent

Making Root Positions

Root positions have no parent - they're at the top level of the hierarchy. To make a position a root:

• Drag to root zone - Drop the position on the "Root Positions" area at the top
• Click X button - Click the X next to the position name
• Context menu - Right-click and select "Make root position"

Expand and Collapse

• Individual - Click the ▶/▼ arrow next to a position
• Expand All - Click the "Expand All" button to show all children
• Collapse All - Click the "Collapse All" button to hide all children

How Call Routing Works

When someone calls a position:

1. Landline checks if the target position is online
2. If online, the call goes directly to them
3. If offline, Landline looks up the consolidation hierarchy
4. The call routes to the first online parent in the chain
5. If no online parent exists, the call indicates the position is unavailable

Best Practices

Hierarchy Design

• Mirror your facility's actual consolidation structure
• Subordinate facilities should always be children of the primary facility

Common Structures

ARTCC Structure:
    CTR (root)
    ├── APP
    │   └── N TWR (PRI)
    │		├── S TWR
    │   	└── N GND (PRI)
    │			└── S GND
    └── DEP
        └── DEL
