Left bottom. You should see a figure like:

X X

or

XX XX

Where the X's are numbers, there is no decimal so if you see '54' it means 5.4G. Right side, current G, left side, permitted max G under current flight conditions.

I have never owned any Lock On series until last night so I am unaware of the flight dynamics programmed for any of the aircraft, however, it seems to me like the F-15C (the only plane I have studied and flew) has extremely simple game flight dynamics as compared to the A-10C. I have my settings set for simulation and was just wondering if I had a setting wrong or this is just the way it is. The Su-25T has a far more realistic flight model than the F-15C. Any insight would be appreciated.

How to disable, the absolutely annoying, slow zoom out animation when you just start the mission/enter the cockpit?

Correct, the old LO aircraft have a simple flight model. It is adequate for simulating the aircraft's real flight parameters, but it will feel like on rails compared to the A-10C flight model. The Su-25 was added with FC, and it was the first aircraft to feature the advanced flight model (AFM). The AFM itself has gone through several iterations, and will not be retrofitted to the original stable of lock-on aircraft.

Hey Jake, yes you are correct.

The FC aircraft utilize what is called a SFM (Simplified Flight Model) it is defined by a few dozen parameters and a couple tables...what happens with this is that the aircraft utilizing a SFM pretty much all fly and feel the same.

The A-10C utilizes a much higher fidelity AFM where ED has built the flight model from the ground up and probably is using source CFD/Wind Tunnel/Analytical data of much much higher detail than the couple dozen parameters you define within an SFM. It is also probably using the flight control system control laws of the A-10C which really gives it that unique feeling.

The control laws for all the SFM aircraft are essentially the same from what I can tell. For example..do a pitch doublet (quick full throw of pitch surfaces full-up then full-down then back to center) if you watch the dynamic response of the aircraft between say the Su-33 and the F-15 you won't really see a big difference where in reality, their control laws would have dictated the desired response.

Are there any plans from ED to update at least a few of these SFMs?

I cannot tell you how disappointed I am to here this.

I really have no idea, but I don't think that is that plan to increase the fidelity of the flight models.

Maybe a year or so from now when we've solved more of the issues we are seeing with the EFM API, I would love to start working on one, but right now the API is too broken/undocumented/early stages for someone outside of ED to develop, we'll see how things go later

To be fair to ED, they explained pretty thoroughly what you were going to get in the level of fidelity of the flight models well ahead of time. However, being that you had never flown previous lock on sims you would have no idea what level of fidelity a lock on aircraft would "feel like". I can understand how you would think, having only owned DCS stuff, that it would feel at a minimum as good as the SU-25T flight model since you had no other baseline to go off of.

What are EFM and API?

I'm very sorry, I'm not in the How To thread anymore!

I sometimes mix EFM(External Flight Model)/AFM (Advanced Flight Model) since I'm not sure what the differences are...but the EFM is the API that we can use to code up C++ flight models from the ground up and defining the basic forces and moments, it is called "External Flight Model" since you code it up and it compiles as an external DLL that the sim interfaces with. API is application programming interface, meaning that they, so far, have thrown in a dozen or so function that I can interface with to accomplish this.

Does that help? Sorry for the flurry of acronyms!
