Richard Dean Anderson – an American actor who portrayed the heroes of my (and certainly not only my) childhood. Who doesn’t know Macgyver or Colonel O’Neill from Stargate? Well, although there are sure to be a few… under this link you’ll find a fan site written by Kate Ritter, which is the deepest well of information and facts about Richard’s life and work that I’ve come across. It also contains “messages” directly from Richard (although not a tool to contact him). Be sure to visit the site, it is full of interesting things.
SimBrief
SimBrief is another great online service. It is powered by Navigraph. Is focused on flight planning and everything, that is related to it. It include detailed fuel calculations for over 120 aircraft types, an extensive route database, real-world weather forecasts, current NOTAMs, ETOPS planning, and much more! It is FREE, but slightly limited in this mode. It will only allow you to use some older (outdated) AIRAC cycle for computing the flight route, but you can use otjher services for that. If you have Navigraph subscription, you will be able to use the latest cycle. The flight planning is there very fast and you will get all the required information at one place. You can export the flight plan to many formats and some aircrafts also support to import the flight plan directly from your SimBrief account.
FsHub
FsHub is a free cloud service that provides virtual pilot and airline flight tracking and performance monitoring for Microsoft Flight Simulator 2020, X-Plane, Prepar3D, FSX, FSX:SE and FS2004! That is the official saying, and I would add it is wonderfull free service. Also offers many “achievements” to give you more reasons to soar the virtual skies and visit places you maybe did not know about existing.
