Consider first Joan's definition of Maximum Velocity: "These are the settings to which a ship's speed-governors are set. This is always a relative velocity; a ship's computer sets it relative to (a) the flagship, (b) an escorted vessel, (c) a nearby planetary body, (d) a Confederation beacon, or (e) a value derived from radar positions of all visible ships. The velocity is expressed in kilometers per second."
The key term is relative. This means that while the Ferret's maximum speed will always be 500 kps to the Scimitar's 360 kps, it will rarely be actually moving at 500 kilometers per second.
Ok... I apologize, but I fail to understand this. If the Ferret's speed is 500kps relative to another gravitational body (flagship, an escorted vessel, a nearby planetary body etc.) this means that to achieve the 500kps
relative velocity, the Ferret must actually be travelling at an even
greater velocity!
If for example, a car is traveling 50km/h relative to a walking man, who in turn is walking 6km/h (in the same direction), this means that the car is traveling a6t 56km/h... That is of course if the two bodies are traveling in the
same direction...
So what I don't understand is
how the measurement is taken into account in the WC world, how the fighter's speed can be matched and measured relative to something else, which from what I understood is randomly selected, and whose direction compared to the fighter's is obviously changing all the time, because of the constant manoeuvering...
Under optimum conditions the maximum speed of the Ferret will be 500 kilometers per second. These are the conditions that affect all craft in the same area -- things like the effect of gravity, availability of hydrogen and maneuvering requirements. They affect both the Scimitar and the Ferret, enforcing the same amount of limitations on them both. It is only when traveling in a straight line in deep space with excess spaceborn hydrogen that a Ferret can travel 500 kps actual... but it will always out-run the Scimitar at the same rate, no matter the conditions.
Optimum conditions are rarely met. Almost all fighter combat involves maneuvering inside of star systems with a more limited supply of hydrogen. For that reason a fighter may travel as slowly as a several hundred meters per second -- but it will still be traveling at the same ratio of speed compared to all other ships in the area.
Ok, this a bit more clear to me. The fact that 500kps for the Ferret is only a
theoretical value, that can be achieved only is optimum conditions...
However, if the Ferret would be traveling at 366 meters per second while flying over the Ferret, dropping from a theoretical value of 500kps to 266mps seems a
huge drop to me, which is more confusing that it is seeming to make sense (which I guess it does, only I don't grasp it).
