Select the true statement regarding NOTAMs.

The statement regarding NOTAMs that is true is that they can be obtained from Flight Service as part of an online weather briefing, during a phone briefing, or through various FAA online tools designed to search for NOTAMs. This access is crucial for pilots because NOTAMs provide important information about the status of airports, navigation aids, airspace restrictions, and other critical safety information that could affect flight operations.

Utilizing Flight Service for NOTAMs is a standard part of pre-flight planning. Whether pilots obtain this information digitally or via telephone, it ensures that they are always informed about current conditions and any relevant notices that could impact their flight. This resource is particularly valuable in ensuring flight safety, as NOTAMs may alert pilots to temporary changes in airspace or airport operations.

Other options suggest limited or inaccurate sources for accessing NOTAMs, emphasizing that NOTAMs are not exclusively issued for emergencies, cannot be accessed via phone, or are not provided by Flight Service, which diminishes the understanding of how crucial NOTAMs are for all flight operations, not just those in emergency situations.
