Yes this is true, I actually saw an app once that said, dual given, pipeline patrol, or glider/banner towing will not be considered flight experiance towards qualifying (I assume because its single engine/mostly VFR/ time) and in the case of flight instructing they see it as sitting in the right seat riding along. (I am absolutly not saying this is right, I'm just stating the facts), so basically they wanted to know what your multi engine real flying times were (read cross country, instrument) and not much else, I wont debate whether its for better or worse, but the fact is the industry and hiring practices are changing...the definition of a qualified pilot changes almost weekly anymore....
