SAAB JAS 39E/F Gripen - General discussion



In any case, separate movement of the outer and inner ailerons is not implemented.
The same goes for the slats.
This is why takeoff and landing occur at a greater distance than they should.

Even with the front fender control button enabled in the game, they reach their maximum position, but the transition occurs at a speed of about 150 km/h.

There are also many questions about the upward deflection angle of the ailerons even with the maneuver button on.

I agree with this.

Also, i just found a video that show the Gripen taxying and parking and you can see the elevons drooping when the engine is turned off.
Timestamped to 2:57 , the engine is turned off and the elevons droop at 3:27

Even so, at 5:53 you can see that the inner ailerons are down, while the outer ones are raised.

The slats are modeled but not implemented in the game. (((

They are, they move when you turn the plane in the game, but mostly at high alfa maneuvers and i’m not sure if they move during slow speeds and while on the ground.

In the game, at a static position and up to speeds of 150-170 km/h, they move like this.
At speeds above the angle, the deviation is much smaller.

They seem to be moving way to little in-game compared to real life.
360 video from cockpit, you can click and drag the video to turn the camera. Look at the left wing (the right one is video bugged).

They’re not as aggressive for deployment unlike the J-10A/C slats in which I think that’s how they should deploy on the Gripen C/E.

This video even shows the movement of the slats during the maneuver.

video shows it well too. Slow flight at decent alpha the slats are deployed

In WT they barely deploy unless you pull really hard all the way.

Shouldn’t the wings be aligned they definitely aren’t in this, I think the Gripens are more seen with their ailerons being aligned when transporting as we see here.

24 min in you can see both sets of ailerons are slightly misaligned
I think for transport its different then standard landing where we see the ailerons split angles.

For the last two images on the right column, the Gripens don’t adjust their canards as shown in the images, and it’s not like Gaijin is unable to model it. Various other canarded aircraft (aside from the J-10 which suffers the same issues) has the canards angled downward while in a high AoA state.

Gripen A/C and E at low speed and high AoA:


Rafale for example in a similar state. Note the canards angled down and stabilizing the aircraft.:

Meanwhile Gripen IRL in a slow speed and high AoA flight:


I’m curious if there has been a bug report submitted about this. Might be worth submitting if there isn’t one existing. Maybe they might fix the slats issue along with this.
