It is an open-source web application designed to assist flight simulator users who do not have access to the tool (Electronic Flight Bag) that an airline pilot would have. When accessing the application, the user is presented with a list of registered airports and, after choosing one, the runway information, airport frequencies (tower, ground, ATIS, etc.), and navigation frequencies (ILS, VOR, etc.) are displayed. Information on the current weather conditions of the aerodrome (wind, visibility, temperature, etc.) is also presented, both in the official format (METAR), obtained every hour from an external API, and in a text in natural language for better understanding by the beginner player. A user with administrator permission can add and edit airports. Additional modules are available, such as calculation of the wind components on each runway and the descent profile.
