How is ice accumulation prevented on the F/A-18 E/F?

The prevention of ice accumulation on the F/A-18 E/F is primarily achieved through the use of anti-ice systems and adherence to proper pre-flight checks. The aircraft is equipped with an anti-ice system that utilizes heated engine air that is bled off and directed to critical surfaces such as the wings and tail to ensure that ice does not form during flight. This is especially important during flight in conditions where moisture is present, such as in clouds or precipitation, where ice could potentially build up and affect the aircraft's performance and safety.

Moreover, conducting thorough pre-flight checks allows crew members to assess environmental conditions and ensure that all systems, including the anti-ice mechanisms, are functioning properly before takeoff. This combination of active anti-ice systems during flight and diligent pre-flight procedures is crucial for maintaining safe operation in icy conditions.

While de-icing chemicals can be useful on other types of aircraft, they are not the primary method used for the F/A-18 E/F. Regular engine run-ups serve primarily to ensure engine performance and check system functionality, rather than directly prevent ice formation. Heating the cockpit, while important for crew comfort, does not contribute to the prevention of ice accumulation on the aircraft's critical flight surfaces.
