I will not speculating,
but from now with all the concrete fact we have, A/C being in a severe Icing condition, leading to a loss of many parameters
with the full parameters I’ve got now, it is clear for me that A/C condition was out of normal condition
I’m surely an engineer specialist, with quite a good and long experience on this A/C, but rationally, I still can.t explain this !!!!!!!!!!!!!
