What is the first action to take in the event of an engine failure in flight?

The first action to take in the event of an engine failure in flight is to establish your glide speed. This is crucial because maintaining the proper glide speed optimizes your aircraft's performance in a no-power situation, allowing you to maximize your glide range and control the aircraft effectively. By achieving the best glide speed, you can assess your situation more efficiently, manage your altitude, and maintain a controlled descent while you address the emergency.

Once glide speed is established, you can then evaluate your options for a safe landing site, manage any emergency procedures, and communicate with air traffic control if necessary. This prioritization helps ensure the best chance of a safe outcome during an engine failure scenario.
