Final answer:
True. Failure to route the restraint lines properly through the garters could cause serious injury during ejection/emergency egress.
Step-by-step explanation:
True. Failure to route the restraint lines properly through the garters could indeed cause serious injury during ejection or emergency egress.
The garters on an ejection seat are designed to secure the occupant in place during high-speed ejections and emergency egress. Restraint lines are typically routed through these garters to provide additional security and avoid unwanted movement. If these lines are not properly routed, they may not provide the intended restraint, leading to potential injury or even fatality in extreme cases.
For example, if the lines are not routed through the garters and become entangled with other parts of the ejection seat or the occupant's body during an ejection, it can impede their safe exit from the aircraft and expose them to greater risks.
