Which of the following statements about AIRMETs is true?

AIRMETs are indeed designed to provide information about weather conditions that are less severe than those addressed by SIGMETs. Specifically, AIRMETs are issued for weather phenomena that may be hazardous to smaller aircraft, including conditions like moderate turbulence, icing, and widespread areas of reduced visibility, but not to the level of intensity that would warrant a SIGMET. SIGMETs, on the other hand, cover significant weather conditions that could be hazardous to all aircraft, such as severe turbulence, severe icing, and other conditions deemed dangerous.

This fundamental distinction between AIRMETs and SIGMETs is why the statement that AIRMETs concern weather of less severity is accurate. Focusing on this differentiation helps pilots and flight planners make informed decisions regarding safety when operating in various weather conditions.
