I actually didn’t want to make a topic because the forum is full of pilots, but after a intensive search on tje forum I couldn’t find one. So I apolsgize for making an annoying topic.
My question for the pilots or for people who also know: How is the wind (shown in the picture below marked in red) on the PFD measured. Is it taking from a radar on the ground or does the aircraft have an equipment that can measure the wind outside? If it is the second one do you also know the name of the equipment?
