Flight Restricted Zone (FRZ): Function and Operation
Navigating the skies with a drone isn't as simple as pointing and flying. In many countries, including Canada, Vietnam, Ukraine, and the United States, Flight Restricted Zones (FRZ) require advance authorization to ensure safety and security.
Authorization Process in Different Countries
In Canada, the Canadian aviation authority, NAV CANADA, is responsible for managing air traffic and issuing RPAS authorizations. Operators must use compliant flight planning apps to request and receive authorization for flights within an FRZ.
Vietnam takes a more stringent approach, with every drone flight (except under 250g drones) requiring a permit from the Ministry of National Defense. Applications must be submitted well in advance (at least 1.5 weeks) before the flight, with final approval coming from the defense ministry due to security concerns.
Ukraine requires permits for any drone operation outside standard rules, such as flying in no-fly zones, above altitude limits, or at night. Applications must be submitted at least 10 working days in advance, and coordinating with local authorities may also be necessary. During wartime, permissions can be very strict or denied.
In the United States, the Federal Aviation Administration's LAANC system enables near-instantaneous digital authorization at over 1,000 airports. For flights near airports or controlled airspace where LAANC is unavailable, a manual process requires advance application.
Determining Proximity to FRZ Using Drone Apps
To avoid violations and understand when a permit is required, most drone apps integrate up-to-date regulatory data and display no-fly zones (NFZs), flight restricted zones (FRZs), and other temporary or permanent restrictions. Features typically include interactive maps showing restricted airspace overlays, alerts and warnings if flying near or inside an FRZ, and links or direct access to the authorization application portals or contacts for permits.
Examples include DJI’s flight apps, which show no-fly zones and restricted areas globally, or national apps provided by aviation authorities. Using these apps before flight helps drone operators comply with local rules and regulations.
In summary, FRZ authorization involves applying to designated government aviation or defense bodies well before the planned flight, with rules and timelines varying by country. Checking proximity to FRZs can be efficiently done via specialized drone apps that display restricted airspace maps and notify users of authorization requirements. As drones become more integrated into commercial and governmental operations, enforcing airspace restrictions has become essential. Operators should always check the local rules before flying, as FRZ rules vary between countries.
Drone operators in Canada must use compliant flight planning apps to get authorization from NAV CANADA for flights within Flight Restricted Zones (FRZ).
Vietnam requires a permit from the Ministry of National Defense for every drone flight, with applications requiring a minimum of 1.5 weeks' advance notice before the flight.
