Despite numerous attempts and having read many previous posts on this issue, which appeared to have been fixed - see You Tube: DCS DEAD Demo dated Jan 10 2021 below but then undone following a recent patch, there remains a bug that precludes designating more than one TGT at at time when carrying multiple J-82s using TOO. On designating a TGT, the TOO system loads the same TGT information onto each of the weapons. If you designate a new TGT into another weapon, it overwrites all the weapons with the same new TGT information. Therefore, it would seem that it is now only possible to pre-designate and attack one target at a time using J-82 in TOO mode. I appreciate that multiple targets can be attacked in other ways (PP & TOO), but could the J-82 TOO system be modified back to accepting and saving multiple designations, rather than one target at a time?

Got it - thank you both. ML

Thanks Mobius 708 - what is CSS A/P? ML

Thank you Svende_Dellepude. Good spot. It would seem that deselecting the modes does not deactivate the AP. On selecting the AP modes they each appear on the ADV line. Once deselected, the AP mode appears on the ADV line (as you noted). Thus, the only way to turn the AP off is through the Paddle Switch. I wonder if this is the case in the aircraft itself? Many thanks ML

Following Swiftwin9s' suggestion, I have made a video that demonstrates the issue with the trim/stab divergence (apologies for the poor quality but you can see the problem). This appears to be related to prior use of the autopilot before going ‘on speed’ during the ICLS approach. I flew the full approach 3 times: A. Without any use of the autopilot = no issues with time/stab. B. With use of the heading and barometric height holds, disengaged with the Paddle Switch prior to going ‘on speed’ = no issues with trim/stab. C. With use of the heading and barometric height holds, disengaged in turn with the respective Option Selection Buttons prior to going ‘on speed’ = significant issues with trim/stab diverging from a steady ↑12 degrees. These divergences occurred at least 6 times on the final approach as the power was reduced to increase RoD, as follows: 1. 15 secs/4.7 miles pre-descent = ↑16 degrees 2. 46 Secs/4 miles pre-descent = ↑16 degrees 3. 1 min 5 secs/3.5 miles entering the descent on the ICLS = ↑15 degrees 4. 1 min 26 secs/3 miles in the descent = ↑15 degrees 5. 2 mins 27 secs/1.6 miles = ↑16 degrees 6. 3 mins 13 secs/.7 miles = ↑19 degrees – which makes the approach extremely challenging! With each event I needed to add at least 2 blips of trim the counter the divergence and return 'on speed'. Whilst there was a little turbulence it did not unduly affect the approach. I welcome any thoughts or comments. ML PS. excellent diagrams provided above by Cruizzzzer.

Thanks Mobius708. The thread in the bugs forum is describing a very similar experience to mine. I only use auto throttle in the cruise. Yes, there is some turbulence, but a U tube video of the same approach dosent seem to have the same problem. I have downloaded the mission, where the problem occurs at the back end of the approach - but this has happened on other missions. ML

Mobius708 - Thanks for the reply. I am refering to the FCS sub-menu page - having stabilised on-speed with confortable RoD (700fpm), with little throttle input to change the RoD, the trim (STAB) then wanders significantly causing the speed to increase or decrease and the E bracket subsequently follows. In answer to your question - No, on-speed is not maintained, the speed increases or decreases depending on the pitch/stab runaway, which makes the approach very difficult to fly in IMC! I have just flown a straight in approach using the ICLS in the Mission Qual CAT 1 mission and had no diffiuclty at all with the STAB. Could this be a configuration issue - where the gear and flaps go down quite quickly which then causes the FCS to chase itself? Any further thoughts? ML

I keep finding in the later part of an ICLS approach that pitch trim moves from the datum set at a stable 11 degrees and steady on speed, down to 8 and up to as much as 15 with no trim or pitch input, towards the end of IMC appraoches. Can anyone help addrss this issue?

Thanks for the replies. The bombs are BRU-33 CBU-99. I have just tried arming as before, but set EFUZ to Off, and.......SUCCESS! Thank you.

I am at a loss as to how to arm a RET bomb. I have tried different missions and training and cannot get the bomb to fuse. I have also followed two u-tube lessons, but to no avail. Having selected RET, then Auto, then MFUZ to VT 1500, I then select EFUSE to INST and a cross appears through the Prog and RET on the DDI, and Auto on the HUD. Grateful for help in establishing the correct procedure for arming a RET bomb. Many thanks.

Fixed - thank you

I would appreciate some help returning my dcs 2.5 back to a single screen. I was exploring options to show the FCDs on my single screen and selected in Options ‘camera + LMFCD Automatic Placement’. Somehow, this was activated. I now have a split screen with the right hand area showing half of the options page. I have selected ‘1 screen’ but cannot activate it. How do I return to a single screen?
