correct as is My MavF wont launch with lockon.

[DmitriKozlowsky]

I admit. I am stumped. MavF (IR) wont launch.

I am in AG mode

MavF seeker locked ON. Or so it appears.

Master Arm ON

INRNG que

Launch- But MavF wont do it.

Do you have the Mav display uncaged and as SOI? It won't launch through the TGP.

[DmitriKozlowsky]

Its UNCAGED. AFAIK can tell it is SOI. Look at the track. Its says n L MDI UNCAGED

[Furiz]

@DmitriKozlowsky Hey, I saw your track and that dot inside the flight path marker says your HUD has TDC assigned, if Mav was selected there should be an asterisk in the upper right cornet of the Mav display but there isn't one, also Mav did not lock that building, screenshot from your track:

You need to assign TDC to your left DDI (Sensor Control Switch LEFT) and Mav will attempt to lock the target if I remember correctly.

[DmitriKozlowsky]

Omigosh. This module's switchology for MavF is crazy confusing. Its locked on, it shows. Its in range, and its uncaged. Whats missing?

[DmitriKozlowsky]

I dont get something here. 

With Left MDI as SOI, and MavF uncaged, and Master Arm ON. I CANNOT MOVE THE TARGET TRIANGLE!!!! It does not move. When I make HUD the SOI , I can slew the diamond and MavF triangle caret moves with it. Then as soon as I uncage, the MavF triangle goes nuts! It moves by itself somewhere. It does  not slew under my control. I dont understand what its doing. I have no cpontrol over it. But I should. MavF selected, UNCAGED, L MDI as SOI, Master Arm ON. But I get no slew control. Very confusing.

To Slew MavF with L MDI as SOI, uncage, then  hold down TDC DEPRESS while slewing using TDC axis. That does not work. As soon as I uncage the triangle runs away. No control.

Somehow I got it to lock on to the Molnya. But I dont understand of sequence. I dont understand why the slew caret has a mind of its own. Why I cannot slew MavF seeker indepently of HUD?  Why it wont lock on and stay locked on. Whoever designed this is dish!

I just did some tests. As far as I can tell, if you designate a target via another sensor (i.e. HUD...thats what I tested at least), the MAV is uncaged automatically. This is also indicated on the MAV display top right corner. So maybe you have designated a target with HUD already and now pressed the CAGE/UNCAGE button agin and thus accidentially caged the missile again, which would look like it moves uncontrollably. Or also, if there is no heat source to lock onto it will go crazy.

Another thing I´ve noticed: If you have designated a target with another sensor, and you now switch to the MAV screen, you have to UNDESIGNATE (NWS button) in order to be able to move the MAV reticle.

Now I think the MAV should not be used as a poor-man´s targeting pod. You should acquire the target by other means first and only finetune the seeker head if needed.

So, if you acquire the target with your own eyeballs:

Assuming you are A-G mode, MAV selected, Master Arm ON

- SCS forward to make the HUD TDC priority

- make sure MAV is still CAGED, so the MAV triangle is on the boresight line on the HUD

- point the triangle on the target as good as possible

- TDC depress to designate target (missile is now automatically uncaged and more or less slewed to target)

- SCS left to make MAV TDC priority

if MAV is not perfectly locked on target:

- NWS press to undesignate

- use TDC depress slew to move MAV crosshair on target

- closed crosshair on target -> SHOOT

 

I have not tested this now, but the principle should remain the same with other sensors (TGP, HMD).

Thats is dish-bag bonkers! Switchology sequence is absurdly complex

[Phantom711]

I am not very familiar with how it works in the other jets (i.e. F-16, A-10), but once you got the hang of the logic in the Hornet, it makes perfect sense.

EDIT: Just watched a video how it works in the F-16. It´s not that much different from how it works there.
