AVISIM is AVISU’s intelligent airport simulation and analytics platform. AVISU is a specialist Air Traffic Management consultancy that advises customers across the air transport industry on procedures and technology, with the aim of improving operations in terms of safety and efficiency.
The airport domain is a key focus area for AVISU as traffic numbers continue to rise globally and infrastructure costs and risks increase. Realising capacity growth is complex, and new systems and procedures are increasingly difficult to assess on a business-case basis. AVISIM was born out of the desire to improve the quality of data used in how AVISU analyses a subject and presents advice on the path forward.
It has a powerful capability to simulate changes in the way airport surface movements occur, assessing the benefits in time, fuel, safety and gate allocation. AVISIM can perform analyses linked to airside surface operations across a variety of environmental conditions, airport systems capability and operational procedures — providing performance evidence to back up decision-making on the efficiency and safety of surface movements.
Runway and intersection analysis
AVISIM provides an assessment of runway usage, with analytical output on a range of indicators from intersections to occupancy and runway allocation. The most revealing analysis is when bad weather or peak periods combine, exposing how the operation handles pressure and where improvements can be made. Intersections are where the majority of safety and efficiency problems exist; AVISIM’s graphical interface is ideal for identifying hotspot intersections in fast time across present and future scenarios.
‘What-if’ capability
AVISIM has the capability to perform ‘what-if’ analysis to prove benefit cases or to assess planned infrastructure or procedure changes on the horizon. The software is exceptionally flexible, enabling any planned infrastructure and procedural changes to be modelled and their impact on performance assessed before commitment.
Taxi and turnaround performance
Moving aircraft and vehicles around the airport surface is complex and unpredictable, making resource planning and runway utilisation inefficient, and severely impacting On-Time Performance. AVISIM analyses large volumes of data on movement to assess indicators from taxi times to taxi speeds. A critical area linked to customer satisfaction is turnaround management, which impacts gate allocation, runway utilisation and compliance with departure slots. AVISIM identifies gates where turnaround performance is degraded and correlates this to weather, peak periods, aircraft type and international versus domestic traffic.
How AVISU helps
AVISIM puts measurable evidence behind airport surface decisions — before capital is committed.
