When should emergency procedures be invoked?

• A. Immediately when the emergency occurs
• B. Only after ATC approval
• C. After landing
• D. At pilot discretion

Answer: (A)

In an emergency, acting right away is essential to stabilize the situation, preserve the aircraft’s control, and ensure timely coordination with air traffic control. You invoke emergency procedures the moment the threat is detected, which includes declaring mayday and starting the relevant memory items and QRH steps without waiting for anyone’s permission. This immediate action gives you the best chance to address the danger, set proper priority for your route and alternate options, and let ATC assist with traffic management and rescue coordination once the emergency is declared. Delaying for approval or waiting until after landing introduces dangerous delays; choosing to act now aligns with how emergencies are managed to maximize safety.
