Which of the following is true regarding airspace authorization?

Airspace authorization is a crucial aspect of maintaining safety and efficiency within the National Airspace System. The statement regarding working near Class B airspace being a requirement for authorization is correct. Class B airspace, which surrounds major airports, is designed to manage high volumes of traffic in a controlled environment. Pilots operating within or even near Class B airspace must have specific clearance to ensure that they do not interfere with commercial and dense general aviation traffic, as this area is characterized by heavy aerospace activity and strict operational protocols.

When pilots approach Class B airspace, obtaining authorization from air traffic control is necessary to ensure that they can enter and operate safely within that airspace. This includes understanding the lateral and vertical limits of Class B airspace and following the established protocols for communication and navigation.

The other statements do not accurately represent airspace authorization requirements. Class G airspace, being uncontrolled, typically does not require prior authorization for operations, and operations in Class D airspace do not solely require authorization—though pilots must contact the control tower before entering to communicate their intentions and receive necessary instructions. Understanding these distinctions is vital for any pilot operating in diverse airspace environments.
