2. Private aircraft only

3. All aircraft

4. Military aircraft only

The correct answer is: All aircraft

SIGMETs, or Significant Meteorological Information, are issued to warn of weather conditions that are hazardous to all aircraft regardless of their operation type. This includes commercial, private, and military aircraft. The primary purpose of SIGMETs is to provide critical information about phenomena such as severe turbulence, thunderstorms, icing, and volcanic ash that can pose risks to flight safety. These warnings are comprehensive since adverse weather can affect any aircraft, and pilots must be aware of these conditions to make informed decisions about flight safety, route planning, and in-flight operational adjustments. By catering to all types of aircraft, SIGMETs help ensure the safety of all pilots and passengers flying under various regulations and operational contexts.
