Meet our RPAS and dangerous goods experts at Avalon


Is the flying car really the future of air travel? Will drones finally take over your parcel delivery and render your local postie redundant? Are vertiports actually more than just glorified helipads?

Avalon airshow biplanes flying in a pair

That's just a few of the question our remotely piloted aircraft subject matter experts (SMEs) will be on hand to answer at the Avalon Airshow next week.

Drop in at our brand-new stand in Hall 1 - 1G21 and have a chat to one of our emerging aviation technology specialist's, Simon Butler.

While only a year into his role at CASA, he's tasked with developing the people items described in our Remotely Piloted Aircraft Systems and Advanced Air Mobility roadmap.

Simon also has 21 years' experience as a professional helicopter pilot with a background in oil and gas both in the UK and around Australia. He was also an all-weather search and rescue for the UK coastguard.

He holds airline transport licences from both the UK and Australia, as well as a commercial pilot's licence and instructor rating from the US Federal Aviation Administration.

Our other SMEs on the stand include:
