In which classes of airspace can traffic information help pilots to avoid collisions?

The correct response is the option that includes classes B, C, and D of airspace. In these classifications, traffic information is actively provided to pilots to enhance situational awareness and assist in collision avoidance.

In Class B airspace, which surrounds major airports, air traffic control (ATC) provides detailed traffic information to help pilots maneuver safely among a high volume of air traffic. This includes both transiting aircraft and those in the terminal area.

Class C airspace, typically surrounding mid-sized airports, also benefits from ATC-provided traffic information. Pilots operating within this airspace can receive alerts about nearby traffic, allowing them to make informed decisions about their approach, climb, or descent.

Class D airspace, associated with smaller airports, features ATC services that inform pilots of other known traffic in the vicinity. Although the scale of operations might not be as extensive as in Class B or C, this information remains crucial for maintaining safety and preventing collisions.

Conversely, Class A airspace, which is primarily at high altitudes for high-speed jet operations, operates under different regulations wherein pilots do not typically receive the same level of situational traffic information to avoid collisions. The nature of Class A operations relies on radar and positive air traffic control,
