I have often found when I'm on top that the cloud just keeps going up and before long I'm starting to worry about airways. I have an IMCr and would hate to be up there without having the skills to let-down safely.
If you have an IMC rating why not just fly through it if there's an airway bothering you? Depending on icing levels etc yada yada.
Is it just me that finds instrument flying very satisfying?
