Where is controlled airspace

The good news is that the different types of special use airspace are pretty easy to identify with their unique codes and symbols. Most of these symbols are summarized below:. P and are marked by solid blue lines with hash marks. As its name implies, drone flight in Prohibited Areas is strictly restricted, even if you have secured airspace authorization in the area.

Prohibited Areas are typically declared for the sake of national security and welfare. R and are marked by solid blue lines with hash marks. Drone flight in Restricted Areas is not completely prohibited, but a drone pilot will need to secure authorization from the appropriate controlling agency. This agency may not necessarily be the FAA, as Restricted Areas may involve testing of military artillery and missiles. Approval of requests to fly drones in Restricted Areas is upon the discretion of the controlling agency.

W and are bounded by solid blue lines with hash marks. Drone pilots may fly their drones in Warning Areas even without prior authorization but are advised to exercise extra caution.

Air traffic activity in Warning Areas is not as severe as in Prohibited and Restricted Areas but may still be hazardous to non-participating aircraft. A are marked with solid magenta lines with hash marks. Air traffic over Alert Areas is expected to be unusually high typically because of flight training exercises and air shows.

Another aspect of air traffic in Alert Areas is that it can proceed in ways that are unpredictable and unusual. There may not always be a controlling agency for an Alert Area, so a drone pilot may proceed with their operations without securing prior authorization. Military Operation Areas MOA are bounded by solid magenta lines with has marks and are labeled in a manner that is very hard to miss e. Military activities in MOA may range from training exercises to actual operations.

This means that flying drones in MOAs is extremely dangerous and is not advised. If there is an operation ATC in the area, the facility may provide instructions on whether drone flight is cleared in a MOA. The number can have three digits e. VR , indicating that the military operations are being conducted at above feet. On the other hand, the number can also have four digits e. VR which indicates that the operations are being conducted below feet.

As its name implies, an MTR is a route that is used by the military for flight training. Since the aircraft in these routes fly at very high speeds, drone pilots are advised to steer clear of them.

Temporary Flight Restrictions TFRs are declared in areas where there are temporary hazards or security issues, prompting the restriction of uncontrolled aircraft flight. The common reasons for declaring TFRs include the movement of the President or Vice-President, the presence of special foreign dignitaries, large-scale entertainment or sports events, disaster relief, or emergency response.

One thing common with all these reasons is that they are very serious, so a TFR is not something to be taken lightly. Drone flight is strictly prohibited in TFR areas unless authorization has been granted by the proper agency. The database is arranged chronologically by default but can also be filtered by state. Sectional charts are an invaluable tool for situational awareness and flight planning.

Looking at sectional charts can seem overwhelming for beginners. With a bit of patience, you will eventually learn to make the most out of all the information that a sectional chart offers.

Airports and airport information Airports can be found all over sectional charts and are some of the most important points of interest. Elevation The airport is located at an elevation of feet MSL above mean sea level. Terrain and obstacles Aside from points of interest, sectional charts also provide guidance for pilots to avoid obstacles and to fly above constantly changing terrain.

Terrain contour lines Contour lines connect points of equal elevation. The graduations between the lines may vary based on the resolution of the map, but intervals of 50 to feet are common. Terrain shaded relief Shaded relief maps are a way of visually representing the terrain of the map by allowing the viewer to see the terrain features as if there is a light source from the north-west.

There are also several other symbols found in sectional charts to represent various types of obstacles, as summarized below: Maximum Elevation Figure MEF The MEF represents the highest elevation of any terrain or man-made features in a quadrant. Its figures are rounded up to the nearest hundreds are expressed in hundreds of feet.

For this example, the figure refers to feet elevation. This database is updated as necessary and each obstacle is evaluated before being added to sectional charts. Checkpoint Obstacles denoted by a black and white symbol are those are used by the FAA as checkpoints. Lighted obstacles Lighted obstacles are those that have high-intensity and strobing lights Controlled vs.

In sectional charts, MOAs are commonly described with details on the times of operation, altitudes affected, and the relevant controlling agency. MOAs are indicated in sectional charts by a solid magenta line with hash marks. The labels for MOAs are impossible to miss e. Similar to MOAs, Alert Areas are patches of airspace where an unusually high level of air traffic is expected.

The military typically uses Alert Areas for flight training and exercises. What this implies is that aircraft flying over Alert Areas may behave in unusual and surprising ways, perhaps at altitudes and speeds that you would not expect. This can place your drone in a lot of danger, so extra vigilance is recommended if you really must fly in an Alert Area. They are, however, labeled A-XXX e. National Security Areas are impossible to miss on sectional charts, as they are labeled with a magenta-bounded text notice that requests all pilots to avoid flight within the area.

As its name implies, this restriction is put in place in the interest of the safety and security of personnel or ground facilities. The best thing to do when you spot a National Security Area is to do exactly what the notice says. They also have no set dimensions or controlling agency.

This very vague statement usually implies the disposal of ordnance or testing of some sort of artillery. Another thing that makes CFAs unique is that all activity will stop as soon as the people involves spot an aircraft. In fact, you can fly in and out of a CFA without even knowing. Military training routes, as their name imply, are routes used by the military for flight training activities. As such, aircraft along an MTRs can move very fast and can cruise at exceptionally low altitudes.

This makes it a really good idea to steer clear of any MTRs. MTRs are marked in sectional charts by arrows and labeled with either a VR visual route or IR instrument route prefix followed by a number. An MTR with a four-digit numeral component e.

VR operates at above feet. Naturally, a drone pilot should be more concerned about four-digit MTRs. An area with an active temporary flight restriction TFR is an area where drone flight is limited due to a temporary hazard or security issue.

Most TFRs are implemented for the movement of the President or other essential government officials , disaster relief operations, wildfire response, and large-scale entertainment events, such as sports events or concerts. With multiple incidences of drones having close encounters with manned aircraft over the last several years, we expect the FAA to become even stricter in the implementation of airspace-related flight restrictions for drone pilots. This can be done by simply looking up a sectional chart whenever you go out for a drone flight, noting the location of controlled and restricted airspace and recalling the related flight restrictions.

With enough repetition, airspace classifications can start to become second nature to you. Your email address will not be published. Sign me up for the newsletter! Posted on August 30, DJI has just released the Mavic Air 2.

The configuration of each Class B airspace area is individually tailored, consists of a surface area and two or more layers some Class B airspace areas resemble upside-down wedding cakes , and is designed to contain all published instrument procedures once an aircraft enters the airspace. An air traffic control ATC clearance is required for all aircraft to operate in the area, and all aircraft that are so cleared receive separation services within the airspace. Generally, airspace from the surface to 4, feet above the airport elevation charted in MSL surrounding those airports that have an operational control tower, are serviced by a radar approach control, and have a certain number of IFR operations or passenger enplanements.

Although the configuration of each Class C area is individually tailored, the airspace usually consists of a surface area with a 5 NM radius, an outer circle with a 10 NM radius that extends from 1, feet to 4, feet above the airport elevation and an outer area.

Each aircraft must establish two-way radio communications with the ATC facility providing air traffic services prior to entering the airspace and thereafter maintain those communications while within the airspace.
