Final answer:
The question involves the ACES II ejection seat system and proper handling of reefing line cutter lanyards. The specific answer, which involves a numerical limit on twists around the mortar tube, requires the technical manual of the ACES II, which should be referred to for accurate information.
Step-by-step explanation:
The student's question relates to the correct handling of the reefing line cutter lanyards on the Advanced Concept Ejection Seat II (ACES II), which is an ejection seat system used in military aircraft. The ACES II is a complex piece of engineering, and it is critical to follow the manufacturer's guidelines precisely when maintaining or preparing the equipment. Incorrect handling of components like the reefing line cutter lanyards could potentially interfere with the operation of the ejection seat, putting the aviator at risk.
The question asks for a specification relating to how many times the reefing line cutter lanyards should be twisted around the mortar tube. Without direct access to the ACES II technical manual, it is not possible to provide the exact number. Generally, students and personnel dealing with this equipment should refer to the technical documentation or ejection seat manual specific to their aircraft for correct procedures.
