This post is made under the assumtion that currently the aim assist only tracks for your fastes flying projectiles so I could be wrong about that.
Based on my casual experiance with fighter that feature back-up MGs in a addition to their 20mm and how the aim assist for AA with mixed ammo belt in WT work am I confident enough to say that the aim assist feature in enlisted broken on a fundamental level.
The reason why the aim assist exist is to help novice pilots to actually hit something without the need to commit an eternity to memorise and develop an innate understanding of where to shoot in order to intercept the enemy plane. This process can be very infuriating for beginner as you will struggle to hit anything while experienced players will just shoot you down in an instant before you can react.
This means the aim assist can in theory even the odds in one of the hardest to learn aspects of arial combat. But this is where the current aim assist fails to fully fullfill that promise for a very simple reason that also happens to favor some factions over the othere.
This reson beeing the guns or to be precise the amount of diffrent guns on a plane.
If a plane only has .50cals (like most US planes) it is very easy to determine where the marker would need to be placed as all guns share the same ballistics.
But this is where it gets really interessting for alot of planes.
If a plane has not only 20mm cannons but also low caliber MGs with vastly diffrent velocities and ballistics it no longer that simple. Due to the diffrent balistics it will become impossible for a single marker to predict the necessary lead for both weapons.
You eighter hit the target with the MG and miss with the 20mm gun or hit the target with the MG and miss with the 20mm gun. This mean you never can hit a distant target with 100% of the firepower.
This might be annoying but if you can hit the enemy with the 20mm a few times if will crash and burn regadless of the MG hitting or not.
So your MGs missing is just desireable if means hitting with your 20mm cannons. So surely the aim assist will help new players aim your 20mm cannons to maximise the damage output into the enemy and swich to your MG only once your 20mm are out of bullets.
WRONG!
The aim assist helps you aim the gun type with the most velocity which in fact does mitigate the required lead to some extend in order to “help” new players hit more which does sound good until you remember that larger bullets like the 20mm are subject to more drag and are slower because of it.
This means that the aim assist will only help you hit an enemy with your weakest weapons at distance!
If you want to compete with the veterans you still need to guess where you actually need to aim for the 20mm bullets to hit.
As this is only a problem with planes that feature multiple diffrent kind of guns it does affect some factions more than othere.
The US is rarely affected by this flaw as it is .50 al the way for most planes making it very beginner friendly.
The USSR has a lot of planes with are affected but still have some do not are affected.
Japan and germany feature only planes with smaller backup MG ontop of their normal 20mm with the only exeption beeing the RE 2000 (with only 2 .50cals and no smaller gun) or planes that only feature low caliber guns.
And how does this affect the new player experiance?
It is simple.
This flaw combined with the lackluster damage caused by small caliber MG causes so much confusion for new players as they get lots of hitmarker but the enemy plane just continues flying as if nothing happend.
How could this problem be fixed?
Just manualy set the 20mm as the prefered gun for the aim assist regardless of any othere back-up gun while they still have ammo to shoot and just swich once not.
