Flew an AS350B2 from Louisianna to Anchorage. Saw engine tempreture changes, performance changes, especially taking off at Denver Colorado, which is 5,500ft with a DA of 10,000! due to being 100 degrees outside!

2 big pilots, and bags, wow! we came up very slowly, I was seeing my gauges read some indications I have never seen before.

To Anchorage where the enviroment was totally different. I regularly take off and land with 15- 20kt tail winds, and she handles them just fine. Just need to keep your wits about you. I love the AS350!!
