1.2.3 A-A Missiles still not right



Fired against non-manuevering targets, all missiles seem to do a great job during the initial launch stage of calculating a lead pursuit trajectory so as to anticipate where the target will be at time of impact. However, once the missiles have expended their fuel and begin decelerating they seem to lose that lead pursuit trajectory and slowly fall further and further into a trail pursuit. The result is that if a target is travelling perpindicular to the launching aircraft any missile fired at medium to long range will impact the target aircraft nearly sideways. This results in a whole bunch of unnecessary drag on the missile.







Having never fired an air to air missile IRL I cannot say for certain that this is a bug. However, I would think that modern missiles should predict their own deceleration before it occurs and build in additional heading correction during the initial burn phase to compensate for that planned deceleration before reaching target. This would ideally result in a missile impacting at a 90* angle when fired at a perpindicular target.



Edit: The images below illustrate the current model's tendancy to go 'trail' pursuit on a non-manuevering target during the deceleration phase. As the missile gets closer it continues to fall behind and continuously steers itself to correct before impact. This results in too much drag and reduced range. It should be able to impact a non-manuevering target with very minimal steering correction in the deceleration phase.











Again, this target is not manuevering. Yet the missile ends up impacting it at >45* steering correction even though it was launched with the steering dot in the center of the ASE circle.



Firstly, ED thanks for all the hard work you've put in to the sim and patch 1.2.3. I was excited to test out the new missile dynamics but found one glaring problem: The A-A missiles are all still not quite right.Fired against non-manuevering targets, all missiles seem to do a great job during the initial launch stage of calculating a lead pursuit trajectory so as to anticipate where the target will be at time of impact.
