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...

To70’s Civil Aviation Safety Review 2018

Sadly, the historical lack of fatal civil aviation accidents involving large turbojet-powered passenger aircraft in 2017 was not to be continued in 2018. In fact, the number rose to slightly above the most recent five-year average. Whilst aviation is still one of the safest modes...

Introducing To70 Belgium

We recently expanded To70’s international network of consultants with a new European location in Belgium. The country has many of the same capacity challenges as the rest of Europe, and we believe having a foot on the ground in Belgium with both global experience and...

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...

The problems of setting aircraft noise limits

Earlier this month, the World Health Organisation (WHO) published its long-awaited Environmental Noise Guidelines for the European Region. In it, the recommended maximum annual average level for aircraft noise is lower than for other modes of transport, lower than current EU policy, and lower than...

Impact of noise guidelines for the European region

Noise is one of the top environmental risks to health, according to the World Health Organisation (WHO), and a growing concern. The just-released Environmental Noise Guidelines for the European Region include environmental noise guidelines for transportation noise sources, the impact of which could be considerable...

Fooling ourselves with digital transformation?

The term digital transformation gets tossed around a lot in the aviation industry these days. Digital is apparently the new normal. And the term is often applied to ‘plug-and-play’ tools from IT providers as a sales ploy, regardless of whether it is true. The idea...

Managing departures beyond airports

In this second article on airspace capacity management in growing aviation markets, we look at the advanced technique the aviation industry uses to manage departure demand. When there is too little airspace available on busy routes and adding flight paths is not an option, a...

Understanding all sides of airspace capacity

Building new airports and adding runways to meet capacity demands in strong growth markets, such as Australia, enables more aircraft operations. Unfortunately, with that also comes more constraint points. Understanding the nature of this new demand on the system is the first step in developing...
