Application for the establishment of a danger area (D-area)

The complete application must be received by the Swedish Transport Agency no later than seven weeks before the current time for establishing a danger area.

Processing of personal data

Here you will find information about how the Swedish Transport Agency processes personal data collected via the website and through our e-services (in swedish).

Your application must include the following

1. Contact information (mandatory)

State the organization or authority, including address, postal code, postal address, telephone number, email and contact person.

2. Planned activities (mandatory)

Describe why the danger area is needed, acticities, operations etc.

3. Justification (mandatory)

Justify the need for a danger area and what purpose of the danger area is to be achieved.

4. Designation, lateral boundaries and height of the danger area (mandatory)

Name

State your proposal regarding a name of the danger area. The name should be traceable to the geographical location to where the danger area is located.

Coordinates and horizontal limits including buffer

The danger area must be defined with coordinates in WGS84 format. Please use an appropriate relaxation method to minimize the number of coordinates. The coordinates of the area must be given with the most northwestern point first followed by coordinates continuing clockwise to end in the same originating coordinate.

Example:
625038N 0124302E
624756N 0125849E
624213N 0125126E
624738N 0124025E
625038N 0124302E

When flying with a drone, a safety buffer of 1 NM on the inside of the danger area must be applied.

Use LFV's drone map, the coordinate tool or drawing tool, to draw the area or validate that the coordinates correspond to the desired area. When using other GIS tools that use a different reference system, the coordinates should be transformed to WGS84 (degrees, minutes, seconds). Up to two decimals are accepted.

Upper limit including buffer

State what height (upper limit) the danger area should have

Upper limit is stated in ft AMSL (feet above mean sea level). This means that you must know the highest point of the ground within the danger area.

When flying with drones, a vertical safety buffer of 500 ft on the inside of the danger area must be added.

Use the appropriate mapping tool to identify altitudes to obtain the highest point in the area + flight altitude + buffer.

An example: Highest point within the area = 259m AMSL. Flying in the area is conducted at 120m with a 150m buffer = 529m. Convert 529m to feet and round up = 1736ft which rounded up is 1800ft AMSL).

Other examples:
GND-4000 ft AMSL
GND-FL70 
3000 ft AMSL-FL195

5. Validity periods (mandatory)

Start time date (yyyy-mm-dd) and time in UTC (eg 2022-01-01, 0900)

Closing time date (yyyy-mm-dd) and time in UTC (eg 2022-12-31, 2359).

Specified validity periods

Enter H24 if the validity period is continuous between the date range. If the time period is the same every day, use the term "daily" start time-end time. for example 2022-01-01 - 2022-12-31 daily 0900–1600.
If the time period varies daily, enter the time for each day:

Example:
MON 0900-1600.
TUE 0900-1300.
WED 0800-1300.
THU N/A
FRI 1100-1400.

6. Risk mitigating measures

For UAS-operations risk mitigating measures must be in place.

Please clearly state the risk mitigation measures that is in force, both organizational and on board the UAV.

Examples of risk mitgating measures that are or may be conditions that have to be met are:

• ADS-B IN transponder
• Geofencing or geocage technology
• Usage of correct local hight references
• Position lights
• Active monitoring of one's own system
• Operational autorization(s)
• ERP and detect and avoid measures/routines
• Communication means to other aircraft/pilots
• Capacity for electronic conspicuity

7. Collaboration

Has there been collaboration with other authorities, stakeholders and business actors in the area that may be affected by the danger area? If yes, state who you have had contact with and what the outcome was.

8. Other documentation (mandatory)

Attach a map of the restricted area (preferably made with the Dronechart).

If you fly drones in the specific category according to (EU) 2019/947, please attach a copy of the operational permit.

You may also enter other information that may be important for the Swedish Transport Agency's processing of the case.
