Common altitude reference systems webinar #2

27 March 2018

Unmanned Aircraft Systems (UAS) are getting smarter and more powerful with each day. This makes certain UAS operations challenging when considering altitude/height as the 'pilot's' reference points and equipment are not the same as with manned aircraft. This becomes a very serious issue when UAS operate in very low level airspace.

To address this, we are pleased to invite you to our webinar on common altitude reference systems for UAS.

Our online event will be an opportunity to share ideas on how to better integrate UAS into airspace. The webinar will be two hours long and will address:

  • the definition of altitude with regards to UAS operations,
  • discrepancies concerning the reference points, usage of equipment and use of the term “altitude” when referring to UAS operations and
  • areas of concern when referring to small UAS operations or operations close to airports


Register to the event and you will receive instructions, followed by a link to the webinar.

Due to unforeseen circumstances the event has been postponed. More information will be provided soon.

If you cannot join this iteration, you will be able to find deliverables from the event on this page. You are also welcome to join the next airspace assessment webinar.

How to join

We will host this webinar via WebEx. Once you have registered, our organisers will send you a link to the conference. If you do not know how to join a WebEx conference, watch this video:


This joint EUROCONTROL-EASA webinar is part of a reocurring series of three such events with the aim to discuss the problems associated with integrating Unmanned Aircraft Systems (UAS) into the airspace along with manned aviation. The series focuses on three distinct issues:

  • Flight rules,
  • Airspace assessment and
  • A common altitude reference system.
