Intuitive airspace visualisation

Presenting 3D geographical data in a 2D report in a way that is intuitive for multiple audiences is challenging. Important characteristics get lost in a flat representation. Airspace is typically structured in complex 3D shapes and flight tracking is incomplete without information on altitudes. To...

Applying Airport Noise Zones In India

Airports in highly developed regions have long been required to publish airport noise zones. In 2018, India’s Ministry of Environment, Forest and Climate Change announced a similar requirement, but the criteria, methodology and application are open to individual airport interpretation. Looking to international best practices...

Risk-Assessing Sustainable Energy Solutions For Airports

To70 Netherlands Managing Director Ruud Ummels will be speaking at the ACI Airport Exchange in Abu Dhabi at the end of November 2019. The paper he will be presenting, Successful technical and business strategies to implement solar and wind energy at or near your airport,...

Understanding Aviation’s Nitrogen Deposition Challenge

Compliance with nitrogen deposition regulations has recently become a pressing issue in the Netherlands due to changes to the permit process for activities in and around protected natural areas. Dutch airports are required to include any effect they have in their Environmental Impact Report. With...

Aviation & Climate change: What airports can do

Aviation has a significant impact on global climate change, as aircraft and airport operations release tonnes of CO2 into the air. Though most is emitted during the fuel-intensive aircraft cruising phase, airport operations on the ground and in the surrounding airspace can have a big...

The Challenge of Managing Airside Waste

The worldwide boom in air transport is increasing connectivity, providing jobs and boosting economies. As with most economic growth, however, more air transport generates more waste. The need for sustainability and counteracting climate change is making effective waste management systems at airports invaluable. But one...

Say (how) you feel the noise!

When we imagine aircraft noise, we automatically picture a specifically personal situation with a plane flying overhead. By contrast, aircraft noise exposure policies are made for long-term exposure levels under varying conditions and while balancing the interests of multiple parties. It’s hard to imagine what...

What’s that noise?

There has been some recent debate in the Netherlands about the aircraft noise exposure calculations used to set government regulatory policy. Community groups and experts alike have expressed concerns about the trustworthiness of aircraft noise calculations in general. As noise modelling is a big part...

Could Schiphol’s future be at sea?

Relocating Schiphol Airport from the Netherland’s densely populated west coast into the North Sea is an idea that comes up from time to time, most recently from Schiphol’s own CEO. If anyone can engineer a large offshore island airport, it’s probably the Dutch. However, engineering...

Aircraft noise modelling: migrating INM to AEDT

The Integrated Noise Model (INM) used in Australia for modelling aircraft noise has reached its final iteration and is due to be replaced over the next few years. Some differences in how noise contours are modelled in the newer AEDT application will require careful management...
