Yep, we saw that performance really well a couple of days ago. I was flying a Phenom back from Brazil and had to climb from the low teens (IIRC) to the mid-30's with the Engine Ice and Wing/Stab protection on. I think from T/O to TOC (FL380 IIRC) it took us about 45 mins. Of course we were at Max Gross, and was insanely hot and humid. Today, back in the States, however, in clear air we were still doing between 1000-1250fpm all the way to FL360, again at MGTOW.
On a related note, how do you like the Garmin Prodigy on the Phenom?
