Most of the current ICAO annexes, standards, and other publications are available through Engineering Workbench, a service for engineering and design professionals.
Members of the UND community (having an email address ending in @und.edu) are able to sign up for, and then access, ICAO publications through this website:
You need to sign up with your UND email and a password of your choice when you first click the link:
It does not have to be your UND password; like subscriptions to the New York Times and Aviation Week & Space Technology, the access is controlled by the vendor, not through checking UND IP addresses.
When you sign up, the vendor will send you an access code, that sometimes will take a little while to appear in your inbox. Once you have that, and enter it to complete your signup process, you can sign in through the link above whenever you want to access ICAO materials.
Searching and Reading Engineering Workbench materials
If you know the name of the document you need (e.g., "ICAO Annex 13") you can type that into the search bar and hit enter, and it should be one of the first results. However, many of these documents are available in several languages, so make sure you click the right one!
If you search for a keyword ("UAS," "safety investigator," etc) it will search not just what UND subscribes to, but the thousands of other products the vendor offers for sale (ICAO and otherwise). To restrict your search to just what we have available, click the "My Subscriptions" box on the upper left of the results window:
Notes
If you have any questions, feel free to reach out to the aerospace librarian, Alfred Wallace, for more details.
ICAO -- most recent editions and updates were ordered 3/2017. Print copies will ordinarily no longer be maintained, and materials are now on Engineering Workbench.
