The complete RAMS Plus gate-to-gate model consists of two integrated functional domains, the RAMS Plus Airside and Groundside.

Both functional domains work together in the same environment to provide a global macro/micro gate-to-gate view of the air traffic system being modelled.

The RAMS Plus Airside Features & Benefits

RAMS Plus Airside is a runway-to-runway simulator, where the primary functionality includes:

• 4D Flight Trajectory Calculation, including Great Circle and speed/altitude restrictions
• 3D Sectorisation
• 4D Spatial Conflict Detection
• Multiple Separation Strategies (e.g. controllers, equipment, dynamic situations, etc.)
• AI Rulebase Conflict Resolution

• 4D Resolution Maneuvering (for enroute delay)
• TMA (arr/dep sequencing, SIDS/STARS, Holdstacks, vectoring on approach, etc.
• Dynamic Task Assignment
• 1..N Stream Time-Based Metering with user-defined subscription
• Runway scheduling and runway usage conflicts
• Weather (wind effects on airborne aircraft performance)
• Editor and display environment in standard MS Windows look-and-feel
• Animated simulation graphics and replay mode

Primary objectives of the RAMS Plus Airside include:

• Benefits of NexGen and SESAR implementations
• Propose alternative sectorisation.
• Measure controller workload.
• Measure airspace and conflict complexity/density
• Measure airspace safety in relation to separation violations.
• Impacts of free-routing or RVSM concepts.
• Impact of the ATM system on fuelburn.
• Unlimited views of ATM concepts!

The RAMS Plus Groundside Features & Benefits

RAMS Plus Groundside simulates airport operations from the gate to SIDS & STARS, where features include:

• 1..N Airport Layouts within the same scenario.
• Gate allocation by airline/aircraft model.

• Shortest path taxi routes.

• Taxi link speed and separations.
• Taxi links by arrival/departure, airline, and aircraft model.
• AI Rulebase Conflict Resolution
• TMA (arr/dep sequencing, SIDS/STARS, Holdstacks, vectoring on approach, etc.
• 4D Resolution Maneuvering (for TMA approach)
• Runway scheduling and runway usage conflicts
• Runway accel/decel rates by aircraft model.
• Runway hi-speed exits (by aircraft model/type/airline)/
• Runway back-tracking.

• Runway blocking other runways when in use.
• Running crossing for taxiing aircraft.
• Editor and display environment in standard MS Windows look-and-feel
• Animated simulation graphics
• Delay reports by unlimited criteria (e.g. airline, gate(s), runway, departure queue...

Primary objectives of the RAMS Plus Groundside include:

• Propose alternate runway configurations, including new or closed runways.
• Measuring runway demands and operations.
• Measuring ground delay, for example by taxi times, airlines, arr/dep, average flight delay, etc.
• Proposing taxiway configurations.

Using Both Domains Together: Gate-to-Gate

The Airside and Groundside share much of the same data, and co-exist in the same environment. Examples of data and feature overlap include:

• Traffic schedule and profile definition.
• Aircraft model performance data.
• Airports
• Runway configurations.
• SIDS/STARS

The primary objective of using both the Airside and Groundside features together is to measure the impacts of ground operations/delay on the entire ATM System, providing a gate-to-gate view of the scenario being studied. This gate-to-gate view reflects interaction and knock-on effects of aircraft from departure gate passenger loading to arrival gate unloading.
