Thank's for the answers.
I'am working on a similar project and the FLIR internal heating capacity does not guarantee deicing. Consequently I inquire about this aspect knowing that the lower pitots are behind.
Thanks a lot for your answer "Hehe".
My concern is with potential significant ice accumulation under severe icing conditions and potential flow "disruptions" in front of lower pitots tubes (static pressure error ?) with AoA for exemple.
