Addendums: National Airspace System

Updated: May 13

On these Addendum pages we post small changes or corrections to lessons that have not yet made it into all of the lessons formats (video, podcast, PDF, and quiz). If there are no updates or changes then we will indicate "None" below. Once these addendums have been added to each lesson element then they will be deleted from this list.

Current Addendums

  1. Military Training Routes (MTRs) are discussed at 34:20 in the video presentation. 4 digit MTRs are for route segments below 1,500 AGL (not 2,500). 3 digit route segments have at least 1 portion of the route above 1,500 AGL (the entire route does not have to be above 1,500' just one segment).

  2. Special VFR was accidentally omitted from the lesson video. It has been added to the lesson PDF and will be re-added to the lesson video in an update coming shortly.
