As we previously wrote, operations within 3nm of a DND managed aerodrome will still require SFOCs under the new regulations, and are not part of standard Advanced operations.
For clarification on this issue and its impact on operators that fly frequently in these zones, we reached out to Transport Canada for clarification on how this will be managed:
Our intention is to issue a standing SFOC to cover these types of situations and you should be able to work with DND and NAV Canada to continue to operate as you have been.
This is reassuring to know it can be dealt with under Standing SFOCs.
We have asked further on if an assured UAV is required under such an SFOC and are awaiting further information.
