ABSTRACT. Consideration of the fog regime in the airports area from Moldavia territory (Romania). In the airports area where the possibility of frequent mists and lasting fog exist, there is a risk that the aviation activity shut down for hours and sometimes for days.

Of all the airports located on the Moldova territory, the Iasi airport have lowest risk of occurrence of fog (33 days/year), and the opposite, with the highest number of days with fog, is Bacău airport (57 days/year). Annual average duration of fog case is between 5.4 hours at Iași and 8.3 hours at Suceava.
