Departing VFR, what is the furthest distance you can proceed without an IFR clearance?

• A. No further than 25 miles
• B. No further than 50 miles
• C. No further than 100 miles
• D. No limit

Answer: (B)

When you depart under VFR, you’re not in an ATC-cleared IFR flight path yet, so you’re still under VFR separation. ATC uses a practical boundary to manage traffic when you’re not IFR-cleared: within a 50-mile radius of the departure airport you can proceed under VFR without an IFR clearance. Beyond that distance, entering the en route airspace typically requires an IFR clearance (or a specific ATC clearance to enter). So the furthest you can go without obtaining an IFR clearance is 50 miles from the departure airport. This keeps the control environment manageable as you move from the local terminal area into the en route structure.
