If communication fails, what route should be maintained?

If communication fails, what route should be maintained?

• A. Last cleared route
• B. Filed route
• C. Direct route
• D. Last assigned route

Answer: (A)

When radio communication is lost, you should continue along the last route that ATC cleared you to fly. This keeps you on the path ATC intended and maintains separation from other traffic until you can reestablish contact. If no route has been assigned, you would then follow the next priority in the lost-communication procedures (vectored route, then the route you were expected to follow, then the filed route). In short, maintain the last cleared/assigned route.
