In a retractable aircraft landing gear system operating in cold temperatures, which consequence results when hydraulic fluid viscosity increases beyond design limits?

A)Delayed gear retraction/extension cycles
B)Increased structural gear impact forces
C)Runway surface de-icing chemicals seep
D)Reduced tire pressure system efficiency

💡 Explanation

Increased hydraulic fluid viscosity causes slower actuation rates because viscous drag surpasses the hydraulic pump's capacity to deliver flow. Therefore, gear retraction/extension speed drops rather than experiencing increased forces or unrelated effects like de-icing seepage which are independent processes.
