Which statement defines Alert III?

Which statement defines Alert III?

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

Answer: (D)

Alert III represents the highest level of airport emergency response and is activated when an aircraft accident has occurred on or near the airfield. In this state, the full emergency response is brought online: firefighting and rescue units, medical teams, and the incident command system are mobilized immediately, with coordinated actions for hazard control, casualty care, and site management. The other situations describe less severe conditions or no alert at all: a local standby is for a defect that doesn’t affect landing, no alert means normal operations, and a serious defect without an actual accident would trigger emergency actions but not the accident-triggered level defined here. Therefore, declaring an accident on or near the airport best matches Alert III.
