VFR (visual flight rules) corridor
A pathway through Class B airspace, with defined vertical and lateral boundaries, in which aircraft may operate without an ATC (air traffic control) clearance or communication with air traffic control. These corridors are, in effect, a “hole” through Class B airspace. A corridor is surrounded on all sides by Class B airspace and does not extend down to the surface like a VFR fly-way. Because of finite lat eral and vertical limits, and the volume of VFR traffic using a corridor, extreme caution and vigilance must be exercised.
