Flight model thoughts

[sdflyer]

bbrz,

 

In that experience I had as a student, the nose pitched up suddenly and violently. There is no room for debate about that happening or why. Of course, the plane began sinking AFTER that. It had suddenly lost lift.

 

So, how about we all cut the “mines bigger than yours” crap, and end this?

 

 

I’m going to reply since you quoted me.

We are sharing our experiences. Some of us fly for pleasure, some are commercially, some are teaching ..it doesn’t matter who fly and how. We are trying to establish common ground in understanding of flight physics relative to Spit in DCS to the best of our knowledge. So sorry if it hurts you feeling it wasn’t my intent at all .

My feelings were not hurt. It was my experiences that were being questioned.

Experience affect perceptions. So we all have different perceptions based on our experiences. Sharing them not a reason to get hostile about it

It's very easy to be tricked by our sensorial input...

 

Then, some aircraft pitch down, while most pitch up, on flap deployment... What I really like to see is that a flight simulator tries, within what is possible for the available computing power, to replicate as close to real as possible all of these effects, preferably without any sort of "scripted" effects.... DCS is doing a great job for sure. Can it get better ? Of course it can.... and will most probably because the Spitfire is still in EA.

Am I missing something? With DCS Spit I have to fly with 1 notch nose up trim. With A2A and CloD Spits I am flying 1 notch nose down trim. I heard that Spitfire is a tail heavy plane.

If you're not using a FFB controller, make sure you untick FF in one of the configuration menus, I don't recall exactly which one though :-/

 

I always have to trim the Spitfire IX in DCS nose heavy, or push the stick inflight ... and even looking at the tail you'll clearly see, just like in many real world youtubes, the elevator slightly displaced down...

I’m using warthog hotas. I checked that ff is unticked. Whats going on? :D

@ Jcomm, Vino refers to trim indicator, so type of his joystick is irrelevant.

 

@ Vino, I've been wondering about the same thing for a long time. I think it's the question of interpretation of how trim indicator works. Note that in DCS Spit manual, it's stated that neutral position of elevator tab equals two notches up from the center (?). Thus when we have to fly with one notch up to keep the plane level in DCS, it supposedly corresponds to roughly about one notch of trim "nose heaviness" (as can be indeed seen on external view of the elevator in flight). That would be an equivalent of one notch down in other simulators you mentioned, which I presume interpret center position of indicator arrow as the neutral one.

 

So the plane in all sims actually flies the same way, only the trim indicator causes confusion. Now, which implementation of that instrument is correct for "our" Mk IX? I don't know, though It's difficult not to have doubts about DCS's version, after watching vids like that one:

AH! Ok Art-J, I didn't notice he was referring to the trim gauge... thx for that.

 

Good question regarding which one is correctly implemented. In IL2 BoS we read 0% trim when the needle is up, like during landing on your video. That's the reference I've been using for neutral pitch trim, also in DCS.
