Describe the procedure to leave an airway in order to continue to a destination outside of CAS.

• A. Climb to 7000 ft and proceed
• B. Descend to the destination outside CAS
• C. Request a descent, then when the clearance is given for that action, you can carry out the manoeuvre
• D. Fly direct without clearance

Answer: (C)

Leaving a route in controlled airspace requires approval from ATC. An airway is within CAS, so you can’t just exit or change your mode of flight without being cleared to do so. The proper way is to request a descent because lowering your altitude is the typical way to transition from the controlled airspace that houses the airway to the airspace outside it. Once ATC grants the descent clearance, you execute the descent and proceed to your destination outside CAS as instructed. Climbing to a higher altitude doesn’t guarantee you’re outside CAS, and descending or flying direct without a clearance would violate ATC rules and could create separation hazards.
