• A. Routine maintenance check
• B. Bird strike incident
• C. Aircraft accident on or near the airport
• D. Security breach

Answer: (C)

In the context of airport emergencies, the term 'Alert III' specifically refers to an aircraft accident that has occurred on or near the airport. This alert level indicates a serious situation that requires immediate response from emergency services, including fire, medical, and police personnel. The declaration of an Alert III signifies that an aircraft has either crashed at the airport or is involved in an incident that poses a significant threat to the safety of the passengers, crew, and airport staff.

An Alert III can arise from various scenarios, such as a crash during takeoff or landing, or a malfunction that might lead to a loss of control. The prompt recognition of this alert helps ensure that the appropriate resources are allocated swiftly to manage the emergency effectively.

Other options, while representing important aspects of airport operations and safety, do not match the critical nature of an Alert III situation. Routine maintenance checks are preventive measures to ensure aircraft safety, bird strike incidents pertain to wildlife hazards that can occur but may not always lead to an emergency, and security breaches involve threats that are unrelated to aircraft accidents. Hence, knowing the specific meaning of 'Alert III' is essential for effective emergency management at the airport.
