Why should speeds above VNE be avoided in airships?

The correct answer is that speeds above VNE (Velocity Never Exceed) should be avoided in airships because design limit load factors may be exceeded if gusts are encountered. VNE is a critical airspeed that represents the maximum speed an airship can safely fly without risking structural integrity. When operating at these high speeds, especially in turbulent conditions or gusty winds, the forces on the airship can increase significantly, potentially causing it to exceed its structural limits.

Maintaining speeds below VNE helps ensure that the airship can withstand the stresses from external forces, such as wind gusts. Exceeding this speed could lead to structural failure or loss of control, as the airship may experience loads that it was not designed to handle. Therefore, adhering to VNE is essential for the safety and reliability of lighter-than-air operations.

While other options might relate to operational considerations of airships, they do not specifically address the critical structural concerns that arise when speeds exceed VNE, which can lead to serious safety risks.
