Synopsis: 

Synopsis What is RAMS Plus? Overview of RAMS Plus For those who are not familiar with the tool Las Vegas Example Description Interactive Demo

What is RAMS Plus? : 

What is RAMS Plus? Comprehensive, high fidelity, gate-to-gate ATM fast-time simulation tool Developed originally under aegis of EUROCONTROL, beginning in 1991 Developed, supported, and distributed by ISA Software since 2000 User base FAA HQ, Tech Center, NASA Langley EUROCONTROL Experimental Centre, HQ, CRDS ATC Service Providers, research organizations: USA, Spain, UK, Italy, Portugal, Sweden, Bulgaria, Australia, Africa (ASECNA), Japan, Korea, China…

RAMS Plus CapabilitiesInteroperable Model: 

RAMS Plus Capabilities Interoperable Model Many RAMS Plus Interfaces now open Integrated with several external tools OPGen (Route Optimisation Tool – CSSI Inc.) Augmented Flight Deck Model (AFDM - FAA/ISA Free Flight Model) Common ATM Information State Space (CAISS – FAA/ISA SWIM model) JCAISS/TFM Model (FAA/ISA Traffic Flow Manager model) JCAISS/FOC Model (FAA/ISA Flight Ops Centre model) PITOT (AENA) Multi-Workload Model (MWM – Wickens workload analysis tool) E-TLM (Tactical Load Monitor – RAMS Plus & MWM used to predict future workload)

RAMS Plus CapabilitiesModeling Flights: 

RAMS Plus Capabilities Modeling Flights Flight Plans Aircraft performance from BADA, other sources + wind Radar 4D profiles from radar, real-/ fast-time tools Performance modeled from 4D data; extrapolated if maneuvering required Import/export from other sources ETMS radar, flight plans, adaptation currently supported Other parsers available XML, other import/exports

RAMS Plus CapabilitiesModeling Airspace: 

RAMS Plus Capabilities Modeling Airspace Centers, sectors, routes, … all the usual Restricted zones for SUAs, weather Dynamic schedules Dynamic sectors SUA activation schedules Moving weather fronts, with or without knowledge in advance

RAMS Plus CapabilitiesModeling Controllers: 

RAMS Plus Capabilities Modeling Controllers Two controllers per sector: planning (D) and tactical (R) Controller windows configurable, dynamic Runway Schedule Controller to manage runway demand Handoffs, other events occur based on time/distance or stochastic distributions Select and customize resolution and task rulebases, by sector type if desired

Controller Windows: 

Controller Windows Sector Boundary Tactical Window Flight Path IBE4014 FL350 Planning Window

Conflict Detection: 

Conflict Detection Configurable separation rules Standard, RVSM Optional hierarchy -- nav equipment, navaids, restrictions, controller separations Dynamic multipliers based on relative positions Head-on conflicts can start earlier Conflicts on parallel routes can be skipped Full geometry provided (angles, speeds, headings, cl/des rates, CPA coords, ..)

Rulebases and ATC Events: 

Rulebases and ATC Events Rulebases for conflict resolution, tasks Over 100+ ATC Triggers Aircraft Events: Cruise, Climb, Performance Band, etc. Sector Events: Entry, Exit, Clip/Pointout, etc. Controller Events: Handoff, conflict search/detect, etc. … Actors assignable: controller, pilot, telephone… Dynamic relationships, conditions TactHandoffWeight = 2.0 + (.1 * N_other_aircraft_in_sec) If traffic count > 50% of sector threshold, [trigger task]

TMA Model Improvements: 

TMA Model Improvements Enhanced Hold Stack Modelling Improved Resolution Maneuvers Enhanced Turn Behaviour for RNP modelling Navigational Uncertainty Dynamic Airport Configuration (in work) Integration of AMAN/DMAN CDM Tool (AENA/PITOT)

Ground (Airport) Model: 

Ground (Airport) Model Since Summer 2003 – New Ground Component Fully integrated with airside (and also stand-alone) Continuous Enhancements with Partners Air Services Australia, NATS UK, AENA, FAA … Full operational ground model Ground Controller rules under development Integrates with our (EEC) environmental tools & projects (ENHANCE/INM, AEM, STBEC, ALAQS etc)

Simulation Outputs: Our Philosophy: 

Simulation Outputs: Our Philosophy Every study has different goals, therefore: Record all the details RAMS Plus produces detailed, thorough, parseable ASCII outputs Outputs enhanced as users present requirements Provide a flexible reporting tool: ATM Analyser Driven by XML metadata Users free to choose aggregations, metrics, filters, time steps Reports, listings, exports XML data table and chart for Excel Special reports for more complex metrics: EEC Capacity, sector density/throughput (minute by minute, smoothed)
