What are "lost procedures" in aviation?

Lost procedures in aviation refer specifically to the protocols that pilots follow when they are unable to determine their position during flight. This situation can arise due to a variety of factors, such as equipment failure, poor visibility, or navigational errors. The procedures typically involve steps the pilot should take to regain situational awareness and safely navigate to a known location.

These procedures usually include actions such as identifying landmarks, using navigational aids, communicating with air traffic control (ATC) for assistance, and following established flight paths to safely return to known airspace. Understanding and practicing lost procedures is crucial for maintaining safety during flight, especially in controlled airspace or areas with significant traffic. This knowledge equips pilots to remain calm and methodical in their decision-making when faced with disorientation, ensuring effective navigation and communication during challenging situations.
