Which of the following actions aligns with evasive measures against lasers?

Taking cover is the most appropriate action aligned with evasive measures against lasers. In an aviation context, when a laser strikes an aircraft, it can pose a significant risk to pilot visibility and overall safety. Taking cover can mean maneuvering the aircraft in a way that minimizes exposure or finding a position where the laser’s incident angle is less harmful.

This response focuses on immediate safety by reducing the likelihood of being directly affected by the laser, which could impair the pilot's ability to operate the aircraft effectively.

While wearing ear protection may be important in noisy environments, it does not provide any benefit specific to laser threats. Maintaining steady altitude could be a tactic in certain scenarios, but it does not inherently provide a defensive strategy against lasers. Using laser detection systems may help in identifying the presence of a laser, but it does not constitute an evasive maneuver. Hence, taking cover is the most proactive and effective approach in dealing with the risk of lasers directed at aircraft.
