What are the required operating limits of a glider?

The required operating limits of a glider include specific speed parameters that are crucial for safe flight operations. The correct choice encompasses maximum aero tow/ground launch speed, maneuvering speed, and never exceed speed.

Maximum aero tow speed ensures that the glider is operated safely during towing and prevents structural stress on the glider and the tow aircraft. Maneuvering speed is essential because it indicates the maximum speed at which the glider can be flown while still retaining control and responsiveness during maneuvers, particularly in turbulent conditions. Never exceed speed is a critical limit that marks the maximum speed that should never be exceeded under any circumstance to avoid structural failures or loss of control.

While other options mention various speed and performance metrics, they do not collectively reflect the required operating limits essential for the safe and effective operation of a glider in day-to-day practice. The other options might include parameters that are relevant in certain contexts but do not address the comprehensive set of operating limits necessary for glider flight safety.
