Answer 22

An authorization issued by an ATC unit for an aircraft to proceed within controlled airspace in accordance with the conditions specified by that unit.

Question 23

Non - ATS Surveillance Route

Answer 23

A route on which an aircraft can determine its own position, track and consequently its minimum IFR altitude without the benefit of ATS Surveillance information
