From 13-23 November 2020 Navigraph is conducting a FlightSim Community Survey together with several major addon developers and organizations within the flight simulation community. The survey, the largest of its kind, aims to gauge the prevailing flight simulation trends and users’ requests for future development.
Like previous years, this survey has an emphasis on the major flight simulators including Lockheed Martin’s Prepar3D, but now also includes questions about simulators on mobile devices, combat simulators, and helicopter simulation.
This is the largest and most comprehensive flight simulation survey in the world! By participating you are influencing the future of the community.
On the 10th of December (tentatively) results will be presented on https://blog.navigraph.com.
The following list of updates has been categorized based on the installer required. The Client installer is required for Prepar3D v5.1, however the Content, Scenery, and SDK installers are optional. You must first have Prepar3D v5 installed to utilize the Client only installer.
To install the Prepar3D v5.1 Client, you must first uninstall the previous Prepar3D v5.0 Client through Programs and Features in Windows Control Panel. Do not deactivate your license when prompted. If you selected to deactivate your license during uninstallation of your current Client, you will be prompted to reactivate Prepar3D.

FSFlyingSchool is an add-on team of artificially intelligent instructors for Lockheed Martin’s Prepar3D v5. It provides talking instructors to pilots on any flight, in any powered airplane, anywhere in the world. From the moment the flight starts, to the time the pilot walks away, the instructor is monitoring the pilot’s actions and will comment on and advise in hundreds of different areas, from airmanship to taxiing – navigation to weather considerations, and a great deal more.
Pilots have been flying with FSFlyingSchool for 14 years, during which time it has won 5 Classic Product Awards from PC Pilot Magazine.
Over 70 areas of airmanship are monitored during flight and full logs are maintained which can be reviewed later and indeed analyzed by several powerful tools built into FSFlyingSchool.
Pilots can talk back too. The voice command pack allows the pilot to ask for lots of useful information and to keep the instructor informed of the pilot’s intentions – this in turn leads to a deeply immersive simulation.
Optionally, pilots can position the aircraft for approaches to any land runway in the world within seconds by using the ‘On Approach’ function of FSFlyingSchool with a few mouse clicks. These approaches include final, intersecting final, downwind, base and entering the pattern.
In addition, 15 specific popular aircraft are covered in a greater level of detail. The instructor knows their checklists and details such as power settings, fuel management, v-speeds, carburetor heat, cowl flaps, primer, fuel pumps, propeller levers and much more.
Pilots can try all this out with the free demo which has no time limit and comes with a full set of manuals.
