Gee whiz guys, maybe folks just did not understand what Pyro and HT said about the system. Allow me to quantify;
1) The PL is an augmentation of the current view system. i.e. is does not work automatically, it requires YOU to get a manual line-of-sight visual fix on the target and then press a key to lock the target(? workin from memory HT).
Once locked, AND you do not manually change your view so that the acquired target is not in view, your head will turn through the same motions as your manual view system is. The head turns do not keep the plane centered, but only change when the acquired target reaches the edge of your periphery view.
If you manually change your view and lose visual with the target, you must manually find the target again before the PL starts to work again.
If an obstruction of the target,that is PL'ed, occurs, your view will no longer automatically change and you will again have to manually get sight of your target again, before the PL takes over.
All this assumes you have enabled the PL AND have acquired a visual on the target AND you have not manually switched views so the target is no longer in line of sight.
This system is the best compromise between the way it really works in RL and the way it HAS worked in other sims and best of all, it does not have to be used. It is simply quite ingenious.
Pyro, HT, if I stepped on any toes, I apologize, but the mole hill was starting to look like Mt. Everest.
