How to work with DronView app

DronView is a special module of the AisView application designed for pre-flight training of drone operators and pilots. It introduces users to the layout of the airspace from an aerial perspective, especially at low heights up to 120 m above the ground. The displayed data is supplemented with topographic background and current meteorological information.

The application is operated by ANS CR and is available at or via a mobile application downloadable from App Store or Google Play.

Ukazka DronView
The DronView application does not take into account the risks of drone operation to persons, buildings, infrastructure etc. located on the ground, which are described in the applicable legislation.

The user interface

The basic screen consists of a topographic map of the Czech Republic with a graphical representation of aerial objects together with control elements (buttons). The buttons are used to control the map and associated functions such as printing, searching, switching between languages, switching to MetView (for current weather information), displaying the map layer of grids and obstacles or displaying the help, in which the user can find a detailed description of the application and all its available functionality.

The user can also register and then log in to the application via the map window. Some functions such as flight planning and saving flights are only available for registered users.

Information about objects

Information about the objects can be obtained by clicking on the map. Subsequently, a data window will pop up, in which tabs with their names are displayed for all objects at the click point. The top of the window then shows the geographical coordinates and the times of civil dawn, dusk, sunrise and sunset, together with links to documents setting out the rules, procedures and protective zones that condition the operation of drones. By clicking on the tab with the name of the object, its descriptive data will be loaded and displayed. At the same time, this object is highlighted in dark grey on the map.

Overview of objects in the map
CTR Controlled area (for controlled airports) and special use areas
P Prohibited area
R Restricted area
D Dangerous area
TSA Temporary segregated area
TRA Temporary reserved area
ATZ Aerodrome traffic zone (for uncontrolled aerodromes)
HEL Heliports
SLZ Sport flying equipment areas - areas for flights and landing of Sport flying equipment
PG Parachute glider/hang glider
PGZ Paragliding zone
OBST Obstacle
GRID Display of the limit height below which the pilot must operate drone without violating airport protective zones

The display of objects in the map depends on the height and time filter, which the user can set himself. The default setting for height is <120 m. The default time setting then displays current airspace information for the next four hours. The time is always given in UTC.


Also important to every pilot are NOTAMs, messages containing information about the establishment, condition or change of any aeronautical equipment, service or procedures, or about hazards of which timely knowledge is essential. NOTAMs are drawn directly on the map in DronView app, assigned to a specific object, or displayed via the red "unassigned NOTAMs" window, which lists those NOTAMs that are not graphically represented on the map.

Based on the height and time filter settings, the pilot gets to know the required information about the spaces and their limits drawn to fly with drones at a given time.

Airspace layout changes dynamically over time. It is therefore advisable to plan the flight as close to the start as possible.

Flight planning

The registered user has the option to plan his/her flight directly in the app. Through an intuitive interface, the user plots the flight on the map and adds the necessary information. For the most accurate planning, the application offers several auxiliary tools. This is a search for a place according to the entered coordinates or their precise interpretation based on the cursor movement on the map. The user enters the horizontal extent of his planned flight on the map by drawing a circle, polygon or line. He then specifies his vertical limitation by selecting the maximum flight height and the time limitation by entering the date and the expected time interval of flying.

In a CTR (MCTR in the case of military airports), the new GRID map tool can be used for drone flight planning. This map layer specifies to the user the maximum possible flight height of the drone in a specific location of the controlled area without the need for coordination (with air traffic control and the airport operator).

Saved flight plans are anonymously available on the map as a drone icon for other app users. The reason for displaying the plan is to reduce the risk of collision with another drone or aircraft.

Please note that by planning a flight in DronView you are in no way obtaining a operational authorization issued by the Civil Aviation Authority or ANS.

The user has the option to store his planned flights in folders that he creates himself. Flights can be moved freely within the folders and copies can be made for planning future flights. It is also possible to archive past flights and edit or delete planned flights (flights that have not yet taken place in terms of time assignment).

The user is also offered the option to save information about their drones in the application and thus have a comprehensive overview of them with all relevant information (type, operator registration number, license plate, take-off weight etc.).

When using the app, please pay particular attention to:

  • appropriate filter settings for the intended operating height and weight of the drone (settings are related to the applied operating restrictions),
  • correct input or interpretation of height (AGL - above ground level, AMSL - above mean sea level),
  • the correct setting or interpretation of the flight time or series of flights (the time is given in UTC = Coordinated Universal Time),
  • ground risks that the operation of a drone may pose to persons or infrastructure on the ground (resulting from a general measure issued by the CAA), which DronView does not contain,
  • for planning flights and subsequent work with them in the form of creating copies, deleting, archiving, editing or saving information about drones, it is necessary to register in the application (the interface for filling in the registration data is available both on the web and in the mobile application).
