No, at or ABOVE -30C. At lower than -30C the water particles in the atmosphere are already ice crystals and do not adhere to the inlet surfaces. It states this elsewhere in the NATOPS.

Can someone from ED please confirm they're looking into this at least? I've added the chart one last time so everyone can see the icing conditions that should trigger the inlet ice warning. It's all rather self explanatory. INLET TEMP is available on the DDI engine display and Mach is on the HUD. It's easy to see that it's currently triggering outside of these parameters.

The inlet ice warning comes on literally every time you fly in below zero OAT. It's that prevalent... I know you're saying that inlet icing is not specifically 'tied' to inlet temp but I still think you could model icing conditions semi accurately without taking humidity into account. Sure, we might get an icing warning while there is no visible weather but at least it would be in the 'danger zone' Mach/inlet temp parameters stated in the NATOPS. There are also weather settings in the mission editor that it could be tied to (clouds, fog etc).

Ok, now we're getting somewhere. I'm not saying that activating the anti-ice system on removes the caution or even has any effect on the icing probe. I'm saying that when the icing condition no longer exist (i.e flying outside of the Mach/inlet temp parameters that encompass the 'icing danger zone') the warning should clear as the ice on the sensor melts. This is not currently happening. Also, the inlet ice caution is displaying when flying well outside of 'icing danger zone' parameters.

Read the NATOPS. If visible icing exists on the LEF's there are separate procedures to protect the engine from ice FOD. If no visible icing exists there are procedures to prevent ice buildup (Engine anti-ice switch ON, increase Mach, INCREASE INLET TEMPERATURE ON THE DDI, climb/decend above/below icing conditions). When clear of icing conditions AND CAUTION REMOVED - Engine anti-ice switch OFF.

OK, I've done my own thorough testing now. The icing advisory appears below ~30k ft whenever the outside air temperature is below freezing. Turning engine anti-ice on and increasing Mach has no effect. It seems to go away after a certain amount of time and then return again regardless of whether corrective action is taken. I think we can safely say this is a bug now.

Inlet temp should give a fair indication of inlet icing. That's why the NATOPS says to switch on anti-ice and and increase airspeed until the caution is removed and inlet temp is above 5°C. The icing sensor and inlet temperature probe are right next to each other.

Inlet icing linked to outside air temperature rather than inlet temperature Please see tests done in this post. https://forums.eagle.ru/showpost.php?p=3560450&postcount=121 This chart shows the actual conditions for inlet icing and that they are tied to inlet temperature, not OAT. https://forums.eagle.ru/attachment.php?attachmentid=189390&d=1530993784 The NATOPS stated corrective action is to increase airspeed until INLET TEMP is at least +5°C (10° preferred), which ties in with that graph. https://uploads.tapatalk-cdn.com/20180707/8ebd3763577f0f8cf49c9e52204550a1.jpg

An inlet temperature of 25°C at Mach 0.7 is clearly not indicative of 'icing conditions'. Look here! https://forums.eagle.ru/attachment.php?attachmentid=189390&d=1530993784 At Mach 0.7 it's anything below 5°C down to -7.5°C.

https://forums.eagle.ru/attachment.php?attachmentid=189586&d=1531168120 Put it this way - If the T2 was reading 25°C would you really expect to see ice buildup on the ice detector probe? In that photo of the inlet you posted the T2 and ice detector probe look about the same distance from the engine face. I wouldn't expect to see an engine icing warning above Mach 0.3 unless the T2 was reading below 5°C as listed in the NATOPS and shown here. https://forums.eagle.ru/showpost.php?p=3558278&postcount=29

Ah ok, I've read back through the thread and see what you mean now. Still, it seems to me that we shouldn't be getting an icing warning when the inlet temperature is 20°C even if the OAT is below freezing. Aerodynamic heating should be sufficient to prevent any ice buildup on the detector probe in the first place.

I didn't check. But you're saying I would still get an engine ice warning even with the anti ice system on? That doesn't sound right at all to me. I had it on the whole time. Why would the engine still be icing?

I tested by turning on anti ice on the carrier and taking off. Still got the engine ice advisory warning and master caution. Looks like a bug to me.

Yeah, confirmed bug here. Very weird behaviour.

Same here with my RX480. AMD driver issue with VR I think.

Yeah... I'm guessing it's just a side effect of having an AMD card and the devs not optimising/bug fixing that well for it.

I'm using an Oculus Rift CV1 and this sometimes happens to the menus when I load into the sim. It mostly happens when I exit a mission and click 'Fly again' Running latest graphics (uninstalled with DDU in safe mode and reinstalled) plus chipset drivers and latest bios. Done cleanup and repair on DCS world as explained here https://www.digitalcombatsimulator.com/en/support/faq/709/ AMD RX480

[NOT A BUG] Left DDI graphical glitch Please look again at this image. This is a bug as the HSI text on the blanked out ADV line is still visible as a shadow on the DDI.

I bought it yesterday. Pretty fun and worth $35 but incomplete as it stands. The only issue now is DCS won't stop crashing. Although I've had that problem for a while. Not related to the Harrier.

It's probably related to air pressure and temperature. I'm sure ED have done their research though.

How big is the update for us folks still at work?

I'm finding this really funny sat at work... But the second I get home I'll be whining like the rest of you!

If it's out in the next hour or so, I'm driving home from work at lunch to start the updater!

Waiting impatiently since 2013

Probably intentional. The SA-13 is an optically guided SHORAD system which the A-10C is capable of dealing with. The HARM missile is carried by SEAD F-16's is not capable of targeting Strella's due to their lack of radar emission. Typical loadout for SEAD F-16: Sniper / HTS / ECM pods 2 x AGM-88 2 x Tanks 4 x A-A The idea of SEAD is to disable enemy radars or force them to stop emitting long enough to carry out an attack.
