ifos GmbH

ifos GmbH is a German software company that makes the Flight Planner, a VFR flight planning program with digital ICAO charts. It also offers the Sky-Map navigation app.

Pilots use Flight Planner 6 to plan visual flights on a computer. The software has regular updates through its Update Manager. A recent release added a new variation calculation. It also fixed print problems with approach charts on Windows 11 and added height data to printed NOTAMs, where it is available.

The company sells digital charts for use in both Flight Planner and Sky-Map. Its V500 chart series has a 2026 edition for countries such as Switzerland, Italy, Benelux, Croatia, Hungary, the Czech Republic and Poland. The ICAO chart for Germany and a Lower Airspace route chart for Germany are included in its tripkits and Europe packages. Customers who buy the update guarantee can load new chart versions onto their own devices.

ifos also provides VFR approach and aerodrome charts from the German and Swiss AIP. The German AIP VFR is now part of its AIP-Online service. The software shows weather data from the German weather service, including radar and lightning data. Sky-Map shows information such as airspace, frequency lists along a route, airspace warnings and the new frequency monitoring code that some German air traffic sectors are testing.

The company supports flying events too. It sponsored the 60th International Allgäuflug in 2026, a navigation rally held near Leutkirch. A German ultralight champion also uses Flight Planner to plan his flights.

ifos publishes news in German on chart releases, software updates and changes in its data sources.
