Recently sat an ME flight test on a PA34 and the wx was certainly not the best...what appeared to be some light showers rapidly turned into heavier ones, contrary to very recent METARS and an improving TAF...
A comment was made a page or two back about high throttle RPM keeping the rain off the windshield...rightly so in a single, but not in the twin - being prepared and familiar with your instruments is certainly useful, because on that ocassion I had almost nil forward viz through the screen....still made the test more challenging!
