[REPORTED]Elevation cursor

[Fox One]

From real aircraft manual:

 

"The antenna elevation position is independent of aircraft pitch attitude, and the angle between the antenna and the ARL is indicated by the elevation cursor on the right side of the scope display."

 

The antenna being pitch stabilised in search, this means if the plane maneuvers nose up, the elevation cursor moves down, and if the plane maneuvers nose down, the elevation cursor moves up. Currently the elevation cursor doesn't move when changing aircraft pitch.

 

Here you can see the elevation cursor moving during maneuvers:

I'm also wondering about this.

 

First I thought that the attitude was taken into account, and from the definition in the manual it seems to be confirmed:

 

- pg. 142, ARL is the line of reference for the armament and is only relative to the aircraft;

- pg. 150, elevation control is relative to ARL (45° up to 40° down).

 

Then there is the elevation correction mentioned by Fox One, if the attitude changes.

 

But in DCS 1.5.5.58891.190, it still seems as if the F-5 doesn't care about the attitude, the elevation is only relative to the horizon. If I have a target 20° up, and find the radar echo by setting an elevation 20° up, then move the aircraft attitude to point directly at the aircraft, nothing changes for the radar, the cursor remains at 20°, and the echo remains visible.

 

Did I misinterpret the manual? I didn't test if an attitude change of more than 40° would make the echo disappear.

Currently in simulator the elevation cursor in search mode is obviously showing the angle between the antenna and the local horizon. Antenna pitch stabilization in search works fine, it's just the elevation cursor that is incorrect.

 

Real manual states clearly enough that cursor shows angle between the antenna and the ARL, which implies that due to antenna pitch stabilization in search, if you change pitch the elevation cursor should move.

 

In video link in first post it is clearly visible that elevation cursor moves in opposite way to the nose movement in pitch - nose moves up, elevation cursor moves down. Just as expected from flight manual description. So there is no misunderstanding of the system on my part.

Did you put the correct video link? I didn't watch the entire clip, but all I saw was the pilot looking at the window to stay in formation with the flight leader. If that's at a specific time, could you please tell us so we don't have to go through the entire video?

 

So I think we both agree there is stabilization in pitch and roll when in search mode, but there is a problem with the implementation of the elevation which should be relative to ARL and not the horizon.

It's a 360 deg video. Use the mouse to rotate the view until you see the instrument panel. What is interesting to this thread starts at 63s as my original link shows.

Huh, interesting find. I'm sorry that I've read it so late. We'll look into this issue and correct as needed. Thank you for feedback!

That's so silly of me :D Yes, I can see it now.

This would make the radar a lot easier to use. Good find!

This would simplify things and make it much easier to see aircraft that are on the radar. You if you detected a bandit at 10 degrees radar elevation you could then match the elevation bar on the radar to the 10 degree marker and know that the target is right on the nose.
