What is VREF Aviation?

VREF Aviation is a global aviation industry benchmark, providing valuable insights and analyses to airlines, manufacturers, and industry professionals. With its extensive research and knowledge base, VREF helps its clients make informed decisions, drive efficiency, and optimize their operations. But what exactly is VREF Aviation, and how can it benefit the aviation industry?

Overview of VREF Aviation

Established in 2008, VREF Aviation is a data-driven aviation company that operates under the Dutch Aviation Centre (DAC). DAC, in turn, is owned by the International Air Transport Association (IATA). This strategic partnership between VREF, DAC, and IATA has allowed VREF to leverage its unique positioning in the global aviation ecosystem.

The Concept Behind VREF

VREF’s primary goal is to create a shared, impartial, and auditable foundation for benchmarking and analysing the operational and financial performances of airlines and aircraft types. To achieve this, VREF relies on meticulously gathered and refined data on fuel consumption, aircraft type, route structure, route characteristics, weather, wind, and numerous other operational and environmental factors.

This comprehensive data, which can be sourced from various systems and data feeds, provides VREF’s expert teams with the essential building blocks for constructing benchmarks, trends, and industry-specific indexes. By focusing on quantifiable and reproducible analysis, VREF eliminates uncertainty and enables companies to effectively evaluate their operations.

How VREF Aviation Measures Performance

To determine operational performance, VREF combines and weighs relevant factors based on the specifics of a given airline’s operation or a specific aircraft type. Some of these factors include:

• Fuel consumption, in units such as Kilogram per available ton of aircraft capacity per unit-distance (KPT/A/t-distance)
• Departure delay minutes per 10,000 blocks flown (DB)
• Cancellations, rejections and ground stop, as per the IATA Industry standards (IRSS)
• Seat per Aircraft Hour Available (SPA/Hour/Available)

The following example illustrates the use of the KPT/A/t-distance factor in an actual flight scenario:

• An Airline operates 12 weekly flights between Los Angeles and Shanghai on a wide-body B747-800. This information allows VREF’s algorithm to derive an exact average fuel consumption value and adjust for seasonal changes. This fuel consumption is normalised by calculating it using a fixed, fuel-saturated distance.
• Over the same time period, VREF benchmarks 18 weekly flights for the Airline between Beijing and Shenzhen on an Airbus A330-200. Combining this with data gathered on various variables (cabin configurations, aircraft state, route information, crew qualifications, flight crew proficiency, etc.) generates reliable data.

The goal behind these meticulous procedures is Transparency, Confidence, Efficiency, and Precision, making it crucial to consider them while examining benchmarks. Moreover, by offering comprehensive comparison possibilities for flight-specific operating performances, it simplifies data collection processes, allows accurate estimation and makes crucial for any meaningful assessments across diverse routes or airline business lines.
