What standard specifies the procedure for initiating a PEL after a bird strike?

The correct answer pertains to the standard that outlines the procedure for initiating a Post-Event Launch (PEL) following a bird strike. In aviation operations, bird strikes can pose significant risks, and thus, having a standardized procedure is crucial for addressing such incidents effectively.

The standard that focuses specifically on bird strike protocol, detailing the necessary steps and considerations following such an event, is the one related to bird strike procedures. This encompasses actions that need to be taken to ensure the safety and operational integrity of the aircraft after encountering a bird strike.

The other standards listed deal with unrelated procedures: visual signals, engine malfunctions, and ejection protocols. While these are important in their respective contexts, they do not address the specific actions required for managing the aftermath of a bird strike. Therefore, the standard that specifically emphasizes the procedures associated with bird strikes is the one that should be referenced for initiating a PEL in those circumstances.
