Hi there,

 

I was wondering if the tgp Air to Air mode was implemented as intended.

 

I was doing the air to air training mission and it asked me to use tgp in aa mode to lock a su-27.

 

When slewing the cross onto the su on the tgp screen and tms up to lock it i noticed that there wasnt a diamond or indication present on the HUD. Only the little dot on the tgp screen in which direction the camera was watching.

 

Accidently I overflew the Su-27 and was having a hellavu time locating the SU again. I had to fly and watch the tgp screen where the dot was positioned. I had to have the dot bang on in the middle of the screen and scan the skies through my hud. some time after i saw a pixel through the hud which was the SU.

 

I tried setting the TGP to SOI and then setting the locked su to SPI but all never made any difference to my hud info. I had to resolve to pixel spotting while closely monitoring my tgp screen to get the directional dot dead on in the center.

 

Am I doing something wrong? I can not imagine that this system would not allow a diamond or box on the hud to monitor where my air to air lock is located. Furthermore when I tried to lock the second SU in my tgp screen I had no idea how high or low the camera was looking. Just the general direction it was pointing to.in the manual it states that when first used it will be located 45 mils blabla and dead on in front of you. But afterwards its guess work.

 

Thanks for reading this :)

Yeh I've been wondering about his one also. ED ? Why no Diamond in HUD to denote position of TGP when in Air to Air mode please?

Hi there

 

Ok I don't have the official documentation but according to the beta manual it states this:

 

Figure 478. TGP A-A Target Point Track

7. To initiate an auto-track of the target, press TMS Forward Short. Upon doing so, a tracking gate box will surround the target and the TGP will go into POINT tracking mode.

8. With the target being tracked, you may then wish to set it as the SPI by pressing TMS Forward Long. Once SPI, you will now have the SPI locator line on the HUD to help locate the target when not in the HUD field of view. You may also automatically slew the AIM/CATM-9M seeker to the target with the Slave All to SPI command by pressing China Hat Forward Long. PAGE 571

 

I don't mind there not being a box or diamond present if the real a-10 has this same "deficiency".

 

However in above explanation it states: Once SPI, you will now have the SPI locator line on the HUD to help locate the target when not in the HUD field of view.

 

The SPI locator line on the HUD is not present. I remember reading somewhere to a similair question that airborne targets cannot be set to be SPI. This is not the case however because I was able to set it to SPI and then slave all (being the AIM/CATM-9M seeker) to SPI. So all in all I am now able to find my locked target again by slaving the seeker to SPI.

 

My question has been changed to the following:

 

Should there be a SPI locator line on the HUD when the (point tracked AND set to SPI with TMS forward long obviously) airborn target is out of the HUD's FOV, or, is this an error in the manual.

 

 

edit: Should this thread be moved? I'm becoming aware that this is not a training mission issue but inherent to the avionics/weapon systems.

Manual is incorrect - cannot set an airborne target as SPI. What you are doing is slaving the AIM-9 seeker to the TGP LOS, hence the absence of HUD SPI symbology.

Hi all,

 

@Viper : it is strange, IIRC there is a wedding cake in the TAD when you press TMS up long in the TGP in AA mode with an AC locked.

 

Having the problem mentioned above by Kingpinda (and no AIM9), I "solved" the problem by hooking the wedding cake in the TAD : there appears a "hook box" (with dotted lines) in the HUD, more or less on the position of the AC locked in the TGP.

 

Doesn't it mean that the AC is the SPI?
