Olá! Acho que há muitos Portugueses por aqui, mas é dar sinal.
About the Headwind A330, for the 2020 there aren't many options, or in my view, not better options. Maybe LVFR heavy's will be something to look at, but at the moment Headwind is the best one for me.
About the problems, a new installation appears to solve the fact that the transfer pumps didn't work, but it still very wind sensitive and the nose that keeps trying to climb be it self. At least in the flights I tried.
For sure, it will be solved.
