Hello! I Have an issue with Phenom. I have read all the manuals, emergency checklists ets, but i cannot find any solution yet. So im flying now at 37000ft i have OAT -53oC and my IAS is dead in Both Displays and the Backup also, so i guess that i have ice in my pitot tubes. Since Phenom does not have any pilot heat switches, i opened all the rest anti-ice protections for the engines and surfaces but they have no effect on that. So the question is... what else can i do? Strange but i still have Ground (455kts) and Mach speed (.733kts)... Some people may suggest to fly in lower altitudes but in the current situation that im flying, i think it's not possible (i will have fuel problem then...). Thanks...
