What is an advantage of electric landing gear compared to hydraulic landing gear?

• A. More weight
• B. Less noise
• C. Requires more maintenance
• D. Longer extension time

Answer: (B)

The advantage of electric landing gear compared to hydraulic landing gear is that it produces less noise during operation. Electric systems typically operate more quietly than hydraulic systems, which can generate noise due to fluid movement and mechanical actuators. This reduced noise can enhance the overall comfort of passengers and contribute to a quieter operating environment, which is increasingly important in modern aviation, especially for operations in noise-sensitive areas.

Electric landing gear systems also tend to be more straightforward in terms of design, which can lead to potential benefits in reliability and total weight, but these aspects are not directly addressed by the other options. Elements such as increased weight, maintenance requirements, and extension time would not normally be considered advantages of electric systems when compared to hydraulic systems.
