Also, many steam gauges have a noticeable lag, since it takes a while for pressure to proliferate to the mechanism. Though I only have experience of civilian types, not military. In my case we are talking about between .5 and 1 second, during which a lot can happen in a performance aircraft.

 

Another possibility is effects of rising air, but in that department I am out of my depth since I don't know how the vectors are calculated. Also, since the aircraft is above the cloud line such a discrepancy is less likely.

The FPI comes from inertial data IIRC, not sure about the gauge.

Well, there's also the "option" of pure mechanical lag, again depending on mechanism. Even if variometer data is taken from another source, there might be more lag in moving the needle, depending on how it's made. (Similar thing is why on many steam altimeters you will tap it gently with your knuckle to "loosen" the needle when in a regime of rapid climb or descent - at least in civilian types. I have flown a few aircraft where I didn't have to do this and military applications should be a bit ahead.)

 

All of this said: if the simulation is tight enough that the discrepancy is caused by something like the scenarios described, what would happen in my pants would not be printable. :P

In my flight club's Cessna 150 it takes even longer, I mean the lag thing annoyed the hell out of me in the beginning - I got too much used to super responsive gauges of PC flight sims I guess, and had trouble leveling altitude correctly in the real thing :p So I'm looking forward that DCS makes these gauges work realistically as they do in RL - too bad the weather engine is still totally simple - air just is too smooth.

Ethereal ... why not have a look at how the Su-25/Su-25T VVI works in LOFC ... you might do stuff in your pants ;)

Question.

Why on one of the cockpit screenshots we see on HUD that the flight path vector is below the horizon line - however the (steam gauge) vertical speed indicator shows the a/c is climbing?

Why there is discrepancy between two instruments? Are they using independent systems for measure? Is one system lagging more then the other?

Most probably the screenshot was taken the split second the nose was moved below the horizont.

'cause then I'd have to install it using one of my last activations - after somehow managing to find the Lock On disc. The latter being the bigger difficulty, since it's been missing for quite a while and it's not easy to find yet another one. (Reason why I love digital distribution being that I have had no less than three LockOn discs and the last one's gone while moving house. :P )

 

Though I am now tempted to reassemble my old Athlon machine... I think it's still on the harddrive... Hm... Wonder if the CD is still in that disc drive as well... :P

your answer

 

For heaven's sake people, it's a shot from a pre-alpha build! Relax.

 

I myself am jus' drouling over the L.O.D. of it all.

 

EDIT you're nick picking over the game before its even in beta.... not a lot of devs can make people do that.

No worries! We all know it will be tip-top (at least most cases) on the release date. Edited by Poko24

Maybe it is not a screenshot, but I find it relevant.

My love climbed into A-10C cockpit during RADOM AIR SHOW 2009, here's the picture :thumbsup:

Lucky One :thumbup: Dumb Polish MP wouldn't let me in even if I had invitation from the crew.:angry:

ED, she will enjoy to fly DCS:A-10C too, I'm sure about it:thumbup: So hurry up with the release :) Note the art on the ladder doors, hahaha :D

AFAIK the principle behind Su-25 VVI (which is probably the same in the whole family of Russian machines) is based on inertia - not pressure. So the delay is close to nothing. Plus note the scale/accuracy. Indeed the delay of VVI in Cessna C152 is so long that pilot needs to fly by hood-horizon reference first and then control the vertical velocity on the VVI. I don't recommend preparing yourself for flights in Cessna C152 using LO Flaming cliffs... ;)
