I stand informed. Those definitions seem unambiguous, and that's great. I have not had the occasion to fly such larger helicopters. Hopefully lighter helicopters will adopt those seemingly appropriate definitions in the future.
I will always recall doing my confined area training in the SW300, and getting the inevitable caution light from the instructor as I picked up. He seemed surprized when I did not put it right back down in the area, but rather continued back to base a mile away. I explained when questioned that I dicided on the spur of the moment, that on a perfect flying day, I could make it the mile with an unserviceable alternator, rather than shut down in a hole, and hike out. Next time he pressed the transmission chip warning light instead....
