Hello you lot,

I reinstalled the game yesterday (after mr. Jumoschwanz actually SENT me a better videocard than I had...http://forums.ubi.com/groupee_common/emoticons/icon_eek.gif -Salute-! There IS hope for this community! http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif), and went online. I activated wonder woman view, and noticed something that really looked like a velocity vector in jet fighters over the gunsight. But it wasn't a velocity vector, since it didn't drop when I lowered my speed for landing... So... what is it? Some sort of gunsight?

It was originally designed for carrier landings in PF. It tells you where the plane is going as opposed to wear it's pointing (the fixed centre of the circle). It helps you with your angle of attack so you can perform 3 point landings on the tail of the carrier. Once you get used to it, you switch to cockpit on and Robert's your father's brother, so to speak. If you SHIFT/F1 (or whatevere you've slaved your keys to to change views again) you get the crosshairs you'd be familiar with in Wonder Woman view.

Ah yes, that's what I meant with velocity vector... Might not have been the correct term.

But then I wonder why it didn't drop when my speed decreased... I know it didn't when my speed was 190 in a FW190-A6, and it felt like the plane was dropping. But I'm not really familiar with 402 yet, so it might be me. Anyway, thanks for clearing it up!

If you're used to flying sims that have modern aircraft in them you will notice the difference in how close the velocity vector indication stays to the aircrafts actual center (Except in yaw). Modern aircraft, especially military jet types can easily exceed the usual maximum that can be found in older or less powerful aircraft types which on average is about 15 degrees. Today€s modern jets and even some little prop jobs can easily exceed that with out stalling.

That's what it is indeed, the speed or velocity vector. The following is from ReadmePF.rtf, in your main IL2-FB-PF directory:

If you turn off the 3D cockpit (Shift-F1 by default, with €œNo Cockpit€ set to On in the Difficulty section), you will see an extra reticle floating around the virtual cockpit. When landing, try to keep decreasing your airspeed, and keep the reticle on the centerline of the carrier deck, at about 1/5th of the total length away from the stern. In other words, this reticle shows you the direction of your speed vector, and the landing angle should be about twice as shallow as when landing on a land strip.

If it didn't appear to drop relative to your cockpit, it must have been because you were adjusting your pitch attitude/angle of attack at the same time as decreasing your speed. If you check when landing, it will be dropping on final approach and when flaring... if performing a conventional landing anyway http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Cheers,

Ah ok, I must've done something wrong then.. (I did actually... I landed too fast I think...And one stutter later I was a wreck sitting next to the runway http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif )
Anyway thanks for the info... Not that I fly wonder woman much... But I was wondering what it was 8)
