If you conduct a normal approach, below ETL airspeed, and can maintain a constant angle of approach with a rate of descent below 300 fpm you will have IGE hover power. If terrain permits, in the mountains, conduct the approach along a flight path parallel to your anticipated approach path in a manner that allows an escape route. I have used this method for years in BH212s, BH412s, BH206s and BH407s. This method is a least as accurate as accurate as performance charts although charts should always be a starting point. If there is any doubt, when using this method download weight or find a lower spot.
