Une longue analyse sur le pour et le contre (en anglais et aux USA)

Whatever technology you decide to include in your cockpit, understanding the benefits and limitations of your equipment can help you avoid making the kind of serious mistakes that can lead to problems in flight. And remember, no amount of in-flight weather technology can guarantee that you won’t inadvertently end up someplace you’ll wish you weren’t. Avoiding those kinds of situations goes back to proper preflight planning, a solid understanding of meteorology basics, knowing your airplane’s performance and always having a Plan B for when forecast conditions turn out worse than expected.
