Hello,
A very interesting thread. I would like to add a few comments, but I'm only a casual flight simmer, so forgive me if some of my remarks are a bit naive :P
1) Letting go of padlock. My main problem with the padlock in IL-2 and LOMAC , especially on ground targets, is that as you make your pass you get a vertigo-inducing snap-round of viewpoint that is most unnatural. Sure you disable the padlock manually just as you make your approach, but this seems unecessary. The system should let it go.
2) Direction vs. FOV. Sometimes, I think when I have a padlocked enemy who is drifting from my central vision, it would be preferable to have my view zoom out to keep him in sight rather than stay at the same zoom but track around (and lose awareness of where I'm flying). But I know that zooming in and out can have a penalty cost for fps.
3) Automatically flicking between different views. So, because I find in-cockpit padlock rather unhelpful, I *do* use the out-of cockpit F5 views quite a lot. Maybe it's not the purists' way, and I have no problem with being able to selectively disable these views for MP play, but whatever. What I tend to do is just flick to F5 for a moment to get my bearings, then back to cockpit. I sometimes think that an "intelligent" padlock could maybe do these things automatically - say every 5-10s flick to the F5 view for one second, then zoom out for 1 second, or snap round for 1 second, presumably this is a bit more like the way pilots fly IRL, their head is on the go the whole time and also they are building up a mental picture of what's going on in 3D. So automatically flicking between these different modes would mimic a pilot taking a quick look over his right shoulder, then back to the controls, then visualising what he has to do in his mind's eye if you like, then executing it.
A limited version of the same idea would be to enable more definable snapviews for each cockpit. There could be one set of snapviews for checking your instruments (focus and zoom in) and another for checking the sky around you.
Then, with a programmable joystick, you could even do a macro that snapped you through all these different views, checking the sky around you.
Anyways, just a few thoughts, and the link to that SimHQ article is really nice, mirrors how I feel in many ways.
