Blog: Are View-limiting Devices Necessary for IFR Training?
The FAA talks about view-limiting devices being used during instrument training but doesn't fully explain why they are necessary.

Join me in a thought experiment. Go back to when you began training for your instrument rating. Do you remember wearing a view-limiting device (VLD) of some sort? A hood, Foggles, something that fit over your glasses or otherwise restricted your view so you could (theoretically) only see the instrument panel and not the outside world?

I’d like to raise some questions: what is a VLD exactly and are they truly necessary? And has anyone ever done any research to prove that VLDs are beneficial?
