Inadvertent flight into IMC?-just finished my IMC course, no probs with that one.
Even with an IR or IMCR, entry into IMC can still be inadvertent, and although it may not carry the risks of losing control, it can still entail the risks of icing, terrain avoidance and aircraft separation.
Unless you've put the planning in to MSA and traffic service etc, then you should still look to remain clear of IMC.
