There are some aspects of the radar and locking things up which concern me too, but not for the reasons you suggest. Principally this is because there is a lot of nonsense and misunderstanding where weapons, radars, scanners, detecting and locking targets is concerned. So in actual fact, I would hope that the scanner would be somewhat limited in capability. This would actually make the game a challenge.
I blame a lot of bad war movies for this sort of expectation personally. Alright, we are in the realms of sci-fi with ED, so a bit of 'magic' is allowed, to take into account extrapolated capabilities of weapon technology in a thousand years, but as Scotty always says: 'ye canne change the laws of physics'.
The amount of crap war movies I've seen where some fighter pilot gets a warning as a heat seeking missile tracks him is hilarious. Heat seekers are passive sensors; there is no way to detect such a passive sensor, because it isn't emitting any signal. Then you have the missiles with endless amounts of fuel which can apparently turn around and make several passes at a target (yes, I'm looking at you Behind Enemy Lines with your magical SA-13 missile), and this isn't even getting deep into the fact that they can pull 25G easily and travel at nearly Mach 3. One look at the size of an average AA missile will tell anyone, who cares to think about it, that the rocket motor would only burn for about five seconds, even if we did not know this was genuinely the case.
Then you have the magical cockpit warning receiver which can not only detect the range, bearing, speed, heading and altitude of everything, but also its type and probably what the pilot had for breakfast, and all this regardless of whether the target is transmitting any electromagnetic radiation of any kind whatsoever. The enemy could be parked up on the ground and these magical warning receivers still display the things. How the hell are they actually managing this?
You also have the magical radars which, unlike the real thing, don't give your position away long before you have detected a readable return. These Hollywood wonders don't need to switch between different search and scan patterns, don't need the pulse repetition frequency and strength to be adjusted, can see through clouds, and can apparently 'lock on' to multiple targets flawlessly, enabling the radar to magically guide multiple SARH missiles all at the same time. And they never ever come close to losing that gated aperture return signal sat in a ten degree cone off the nose, even when the aircraft is performing aerobatics that would make most people puke.
Step up everlasting guns. You can cheerfully ignore reality here, despite the fact that, for example, a Supermarine Spitfire Vb had only enough ammo for less than a 10 second burst of fire from its cannons before it had to ****** off home to rearm. And that was one of the best fighters of its time.
I hope ED doesn't pander to all the Hollywood nonsense and actually makes combat a challenge. You know... like it really is when you want to become Elite.
