RT Practical
Madgav
The RT Practical dosn't require flight subject to IFR. In all cases the pilot qualification will be a PPL with no additional ratings. You may be required to transit Class A Controlled Airspace. VFR flight is not available in Class 'A', true. Why do you believe that SVFR transits only apply "in special circumstances"?
In the UK it is true that SVFR flight is not permitted in 'Airways. However, such a restriction is not applied to other forms of Class 'A'.
