What is the maximum speed of the Viking?

The Viking, which refers to a type of sailplane or glider, is indeed classified as a glider. As such, it does not have a maximum speed in the same way powered aircraft do; its performance is instead measured in terms of glide ratios and maneuvers during unpowered flight. Unlike powered aircraft, which rely on engines to maintain flight speed, gliders depend on rising air currents and their aerodynamic design to sustain flight.

The options that suggest maximum speeds, such as 55 knots, 60 knots, or 65 knots, are generally applicable to powered aircraft or specific airspeed characteristics pertinent to those aircrafts' designs. Since the Viking operates without an engine, it does not achieve or maintain speeds measured in knots like a powered aircraft would. Understanding the nature of gliders and their operation reinforces why identifying the Viking as a glider with no assigned maximum speed is the correct approach. This knowledge is essential in the context of airmanship, especially when distinguishing between types of aircraft and their operational capabilities.
