The best thing to do when you spot a National Security Area is to do exactly what the notice says. No ATC clearance is required for VFR flight in Class E airspace, and pilots of all ratings are allowed. Class B airspace is designated where an operational need exists to provide air traffic control service to IFR aircraft and to control VFR aircraft. Also depicted on the sectional chart are all sorts of other types of airspace that aren’t the typical Class A, B, C, D, E, and G. Some are more advisory in nature, such as the Military Operation Areas (MOAs) and some are no fly zones, which result in a chat with authorities if entered. Typically, Class G airspace includes all of the airspace below 14,500 ft. that is not otherwise designated Class B, C, or D airspace. A handy guide to the marks used to identify Special Use Airspace in sectional charts can be found below: As its name implies, all drone flight (and any flight, for that matter) is prohibited in Prohibited Areas even if you have secured prior ATC authorization. Although there is a lot of material that may refer to uncontrolled airspace as Class F, the standards of the International Civil Aviation Organization (ICAO) has declared that there is no such thing as Class F airspace. In the example image above, the blue number in the box is 38, meaning the airspace ceiling extends up to 3,800 feet. This airspace surrounds airports with control towers, and is tailored to meet a respective airport’s needs. If you’re aspiring to get a Part 107 license for commercial drone flight, then you are going to need to know airspace classifications in and out. Flight under both visual flight rules (VFR) and instrument flight rules (IFR) is permitted in controlled airspace. Thus, to identify a class G airspace, one must first look for signs of any of the 5 controlled classes. Thus, accepting or requesting a direct routing that leads outside of the defined airway may put you into class G airspace. In sectional charts, Alert Areas are marked using the same pattern as MOAs. However, class G is not represented on a sectional chart. Take note that although there is no need to secure any authorization when flying drones in Uncontrolled Airspace, you still need to follow general flight rules and restrictions. Also referred to as Class G (Golf) airspace, this is the least restrictive of all airspace types. Canadian airspace is the region of airspace above the surface of the Earth that falls within a region roughly defined as either the Canadian land mass, the Canadian Arctic or the Canadian archipelago, as well as areas of the high seas. Airspace Altitude; Class A: All: Class B: Generally, from surface to 10,000 feet mean sea level (MSL) including the airspace from portions of Class Bravo that extend beyond the Mode C Veil up to 10,000 feet MSL (e.g. Class E airspace is controlled, such as airspace that surrounds instrument approach paths or federal airways, in all other locations other than Class A, B, C or D airspace, not including the uncontrolled Class G airspace. In the UK class G airspace is uncontrolled. VFR flights are separated when flying in B class airspace. (Aviation fact: Altitudes above 18,000 are referred to as “flight level XXX” in hundreds of feet.) For instance, a plane flying at FL380 is flying at an altitude of 38,000ft MSL. Military aircraft travel at high speeds and can be difficult to see, hence the depiction on sectional charts. On one hand, you have the regularly scheduled passenger flights on airliners going from city to city. Most of the reasons for declaring Special Use Airspace are military in nature or have to do with national security, so you’d best heed any rules that restrict or prohibit drone flight in these areas.

In this article, we go through the different airspace classes, the related restriction per class, and how to identify them in a sectional chart. This means that drone pilots need to know if their planned drone flight mission falls within the boundary of controlled airspace. Because it is uncontrolled, there are no communication requirements for Class G, and pilots of all ratings are allowed to operate. Before entering the airspace, a pilot must establish two-way radio communication with air traffic control. In this case, the controlled airspace in the immediate vicinity of the runway starts at the surface and extends up to 9000 feet. ATC approval will be needed for drone flight in Class B airspace. Class D: Airspace from the surface to 2,500 feet AGL above an airport. They are distinguished from other types of special use airspace in that activities are stopped immediately when an aircraft is approaching the area. Like Class A airspace, two-way communication and positive clearance is required before entering Class B airspace, and all cleared aircraft receive separation services. For the drone pilot, the base of the controlled airspace plays huge role in determining whether or not they need to secure ATC authorization before flying. Prohibited areas are charted as a “P” with a number (e.g. However, 12 of them do not allow operations by pilots with less than a private pilot certificate. The mystery of the blue shading . Airspace classes may be one of the most complex topics that a drone pilot needs to know, but it’s also one of the most important. This section does not cite any sources. www.asf.org The airspace above the United States can seem as complex and convoluted as a soap opera plot. Here we show and explain the primary types of airspace found in the US National Airspace System. Uncontrolled airspace is airspace where no ATC regulation service is provided or required, mostly due to practical reasons. a Class E SAE airspace is sitting adjacent to a Class Commercial drone operators are required to get permission from the FAA before flying in controlled airspace. Areas with temporary flight restrictions (TFR) are also considered special use airspace and are usually declared for events that draw huge crowds over which aircraft flight is deemed too dangerous.
