VFR Transit Lanes

Description

• A VFR transit lane is part of a CTR or a CTA released as Class G (uncontrolled) airspace, during daylight hours only, to allow VFR aircraft to transit through airspace not normally used by IFR aircraft.
• When a VFR transit lane is active, aircraft operating under VFR may enter and operate within the lane without a clearance or reference to ATC.
• VFR transit lanes are depicted on VNC with the designation followed by 3 numbers, T---.
