Ah, I hadn't considered that. Is that something unique to PR? I don't recall them being added that way in BF2 ( I see everyone say vBF2, is there a reason for this?). I never payed too much attention to it in game then, as it has very little use when you're trying to kill things. But for bringing a loach in or blackhawk and dropping troops, its handy for not slamming into the ground, as there is no variometer to judge your descent and collision detection with the ground can be a bit iffy at times.
I am not, and will not, argue against the current quickness and speed of the ships. They need to be fast to get in and out quickly. While it may not be uber real, its not a simulation - we don't need pilots going down due to settling, VRS, over/under head speed, etc. Just wanted to point out the HUD thing.
edit: at the gent' who stated the blackhawk has a 'glass cockpit' in real life... not quite true. Blackhawks are old ships, they're mostly analog gauges with a handful of LED indicators for things such as fuel, torque, and some warning lights. Some may be upgrading into glass cockpits like some of the C130's in the USAF are doing, and I believe the newer builds have an
option of glass cockpit, but the majority of BH ships currently flying are not glass.
The new 'hawks also have an FLIR option which gives a helmet mounted hud screen and other features. And a terrain following radar/map which may go well against the 'no mini map' crowd
