AAAE ACE Operations Module 3 Practice Exam

Service levels describe how robust the weather data and reporting are at airports. For Service Level B, the FAA and NWS define it as Level C data plus augmented data beyond what ASOS can provide. In other words, to reach Level B, an airport must deliver the more comprehensive Level C observations and add extra data streams or enhancements that go beyond the standard ASOS capabilities. That’s why this option is the best fit: it reflects both the stronger baseline of Level C and the needed augmentation that elevates it to Level B. The other choices either rely on ASOS alone, or reference Level A, or omit the required Level C foundation, so they don’t align with the official definition.
