Just like air law the theory makes little sense until you start to use it. Trying to practise flying IMC whether on a computer or for real is hopeless without proper instruction.
Being able to legally fly IMC changes the way you plan and execute your trips. It results in a huge boost to your confidence and a lot less cancelled trips.
When you are at home your local friendly airfield
can do IMC training. The guys at Cabro in Aberdeen may be able to do your FAA IR.
