high unwillingly
Last year in the Northern Territory over Black soil plains I was cruising at about 1'000 AGL when the R22 got caught in an updraft. The VSI indicated around the 2000 fpm mark upwards. I had the collective full down, airspeed around 60 kts. the only way i could stop it ascending any more at around 7,500 I started a steep turn and eventually it started to come down. I have around 14,000 in R22's and I have to say it put the wind up me. Nowadays I find I like to stick low before the big updrafts have had a chance to develop.
