Pre-Departure Sequencer
Intelligent Departure Sequencing for Airport Control Towers
First Come, First Served Is Costing You Capacity
Manual departure sequencing leads to predictable inefficiencies that compound across every bank of departures.
Wasted Slots
Departure slots expire when aircraft aren't ready in time. Without predictive sequencing, towers react instead of anticipate.
CTOT Violations
Missing the −5/+10 minute CTOT window triggers Network Manager penalties and disrupts flow across the European network.
Cascading Delays
One missequenced departure creates a chain reaction — incorrect wake spacing forces longer gaps, reducing runway throughput by up to 15%.
Purpose-Built for Tower Operations
Every feature maps directly to an A-CDM milestone or tower controller workflow.
TSAT Calculation
Automatically computes Target Start-Up Approval Time from TOBT, taxi time, and runway constraints.
CTOT Compliance
Sequences departures to fit within the −5/+10 minute CTOT window, minimizing slot violations.
Wake Turbulence Separation
Applies ICAO RECAT-EU wake categories to enforce minimum departure separations automatically.
De-icing Management
Integrates holdover times and de-icing pad capacity into the departure sequence during winter operations.
EXOT Matrix
Stand-specific taxi-out times by runway configuration, updated dynamically for accurate TSAT calculation.
SID Separation
Enforces minimum separation between aircraft on the same or diverging Standard Instrument Departures.
See It In Action
Real-time departure sequencing with full A-CDM integration — from the flight table to the timeline view.
How It Works
SlotAero integrates into the A-CDM milestone approach, from airline TOBT input through to wheels-off.
TOBT
Airline provides Target Off-Block Time
TSAT
System calculates optimal start-up time
Startup
Controller approves engine start
Taxi
Aircraft follows predicted taxi route
Departure
Sequenced take-off within CTOT window
