CommonSenseOTB: in
this post (if I'm understanding it correctly) you seem to be saying you're proposing to change NumericHUDv3 to report the ship's true
forward speed, taking into account any nett velocity component in that direction. Have I got it right?
If so, I assume that you, as a pilot, consider this the best (i.e. most useful/least ambiguous) method of stating the ship's speed. My own personal preference would be to see the ship's true speed in the direction of motion,
irrespective of the direction the ship is currently facing. For much of the time it probably wouldn't matter, as the two would be one and the same. My concern is that, when using military fuel injectors for prolonged periods, the considerable build-up in velocity would lead to some anomalous situations.
The first is where, after giving the mil injectors a sustained burst, I kill the speed and 'coast' to a gradual stop over a period that often exceeds a minute. While coasting, if I spin the ship, I can find myself travelling sideways, backwards, forwards... in fact in all directions. If forward speed is strictly reported, I'll presumably see the speed readout changing, from +300 (say), through 0, to -295, up and down constantly as the velocity decays. Personally, I would much prefer that a speed readout of 0 confirms I'm stationary in space, not scooting sideways at who-knows-what speed.
Another potential situation would arise, I suspect, when the action heats up. I use my (mil) injectors a
lot in combat, so presumably I'm carrying considerable amounts of velocity at such times. Combine that with frequent and often violent changes in direction, and I can imagine significant degrees of 'sideslip' developing, again with a detrimental effect on reported (forward) speed. I
expect to see the speed readout change when I press 'w', 's' or 'i', but
not when I move the joystick: I can't see how that would help me, and in fact it seems likely to prove a distraction.
It's possible I've got this whole thing round my neck and that's not what you're proposing at all. If that's the case, apologies, and I'm happy to be wrong.
