SimBrief

https://www.simbrief.com/

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 It will only allow you to use some older (outdated) AIRAC cycle for computing the flight route, but you can use otjher services for that.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.

VATSIM

Like many people like flying, even if only virtual, there are other people who loves being air traffic controllers, even if only virtual. These two groups meet at VATSIM network, where after registration, which is free, you can fly under control of virtual air traffic control operated by real humans. Almost everybody tries to stick with real world procedures here, which makes VATSIM a great learning environment even for real world flying ATC communications.

Angle Of Attack

nor virtual aviation is about ability to apply full throttle. If you want to learn to fly like a pro, I don’t know better source than Angle Of Attack, where you find professional video training. You can go through basics of flying with small airplanes all the way to “heavy metal” like Boeing 737,747 or MD-11. Aviator 90 – the basic training is for free, but neither the payed courses cannot be considered wasted money at least by my opinion.
