Final answer:
Fire stations serving remote and outlying areas or auxiliary airfields may operate at inadequate levels of service with an approved response time.
Step-by-step explanation:
In fire departments, there are different levels of service depending on the area being served. Fire stations serving remote and outlying areas or auxiliary airfields may operate at inadequate levels of service with an approved response time. This means that they may have longer response times compared to fire stations in more populated areas, but this is considered acceptable and approved for these specific locations.
