How is Class B airspace depicted on a sectional chart?

Class B airspace is depicted on a sectional chart with a solid blue line. This representation is important for pilots to visually identify the airspace boundaries and understand where they need to obtain clearance to operate. The solid blue line creates a clear distinction from other classes of airspace to aid in navigation and maintain safety, making it essential for pilots to recognize this visual cue during flight planning and operations.

Understanding the markings on sectional charts is pivotal as it informs pilots about airspace requirements and regulations. Knowledge of these markings helps ensure compliance with air traffic control (ATC) and enhances safety when flying in more complex airspace environments commonly associated with busy airports.
