With a Pandememic grounding many to their residence.... How to maintain flight hours? No matter your Country, is grounding affecting license requirements(Passenger, Cargo or even Private) and how are the hours being rectified. CNN actually posed a great question in this article and I am also curious to know if this has been addressed CNN: What happens when pilots don't get their flying hours?.

Many countries are extending validation periods, but ultimately it's a question that isn't fully answered yet. Right now the focus is on the pandemic - the practical concequences come second.

Chances are it will be a combination of extending legally mandated periods, and common sense by operators.
