Why PBN is Worth It for General Aviation

As airspace becomes more congested and more noise sensitive, conventional navigation aids can begin to lose the safety and operational benefits they once offered. The advantages of implementing Performance Based Navigation instead are numerous, even for general aviation airfields and many smaller specialist operators. However,...

“It’s Not Rocket Science.” Well, Actually…

You’ve probably heard the phrase “It’s not rocket science” to indicate how something can’t be too hard to figure out. This is because the ‘rocket science’ of Aerospace Engineering is, well, hard. It is a tough field to study, but is it worth it? The...

When an Aeronautical Study Saves Money

Designing an aerodrome that complies with the Annex 14 and PANS-OPS limitation rules on obstacle surfaces can be a complex – and potentially very expensive – exercise, especially near big cities or in mountainous regions. Even less-populated areas can present problems with electricity masts or...

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...

Improving TOBT predictability using actual ready time

Many major European airports have been improving their operational efficiency by implementing Airport CDM information sharing. Some, however, have opted out of a few of the recommended milestones in order to shortcut the implementation process. Not implementing actual event milestones means the airport misses out...

Working on complex ATM performance

The aim of the Single European Sky ATM Research (SESAR) programme is to modernise European ATM. With a very highly complex airspace, Switzerland’s ANSP skyguide is an active SESAR partner, collaborating on multiple projects. To70’s Swiss office has been providing validation and verification support for...

Capacity predictions for runway maintenance planning

When is the best time to plan runway maintenance if you operate a very busy airport? It’s a complicated question, since the answer depends on wind and weather conditions, available capacity, hours of daylight, and the complexity of the maintenance project itself, just to name...

Roadmap to terminal experience excellence

Airports spend millions on implementing new screening technology to make the passenger terminal processing flow faster and as painless as possible. Unfortunately, poor customer service can still completely defeat the purpose of innovations meant to improve the passenger experience. Passengers always remember bad customer service,...

Graduating in airport CDM

A graduation project is not only the final step of your education but also a great way to kick-start your career. At To70, graduate students are allowed a lot of freedom and support in shaping their own graduation projects. In this blog, I want to...

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...
