ATPL Subject Air Regulations (SARON) and Subject Air Meteorology and Regulations (SAMRA) Practice Exam

Air routes belong to Class G airspace. Class G is defined as uncontrolled airspace, where the pilot is primarily responsible for separation and navigation. In this airspace, there are generally no air traffic control services provided, allowing for greater flexibility in flight operations.

Air routes, also known as "Victor routes" in the U.S., are typically used for navigation by aircraft operating under visual flight rules (VFR) and are designed to facilitate flight within Class G airspace, especially when transitioning to controlled airspace. These routes provide a structured path for pilots to follow, even though the environment itself remains uncontrolled.

While Class A, B, and C airspace are all controlled environments with specific regulations regarding communications and navigation requirements, Class G allows for less restrictive operations. As such, air routes are established in Class G to assist pilots while still enabling freedom of navigation in areas where there are fewer traffic constraints.
