Which statement defines Alert I?

• A. Full emergency alert: aircraft defect is serious enough to create the possibility of an accident.
• B. Declared when an aircraft accident has occurred on or near the airport.
• C. Local standby alert: aircraft has an operational defect that does not interfere with routine landing.
• D. No alert is issued.

Answer: (C)

Alert levels describe how prepared the airport’s ARFF teams are for an aircraft in trouble. Local standby is the level used when an aircraft has an operational defect that does not interfere with routine landing, so responders stay ready locally but don’t deploy the full emergency resources. This keeps the airport prepared in case the situation worsens, without treating it as an actual emergency.

The other scenarios describe more severe conditions: a full emergency alert is for a threat serious enough to create the possibility of an accident, an actual accident on or near the airport triggers a different incident declaration, and no alert would apply when there’s no need for heightened readiness.
