PC simulator for IFR
 

What is your recommendation for the best IFR simulator of a PC.
I have windows 10, looking for a sim with an EC135 cockpit mock up.
Only need it to up my IFR skills & knowledge

http://www.luizmonteiro.com/learning_vor_sim.aspx these online instrument simulators are some of the greatest free IFR Sims available, they focus on instrument resins and not the flying, but honestly, it's the lack of knowledge that causes bad technique

Hands down Lockheed Martins Prepared 3D.

For the purpose intended, almost anything, even FS 2002, which doesn't leach into Windows too much, although nothing has a 135 inbuilt as far as I knoiw, unless someone has done a third party mod.

If you want tweakability and more accuraate modelling, X-plane.

Try RANT as they have worked on writing it with EC135 instrumentation.

Belly Tank you are terribly misinformed.

X-plane is excellent. Look to see if a third-party has made a 135 addition that you can buy for X-plane; I bought a 139 addition and it works well, apart from a few minor radio differences.
