Flew to Kuwait and the weather there showed visibility of 2.5 miles. As I made my descent and approach I could see the ground clearly and it was a bright and sunny day. As I decended below 3000ft I was suddenly in thick fog. It kinda reminded me of FSX default weather where it would do the same thing and the low vis just jumps in from nowhere. It's a real immersion killer when a few moments earlier you could see the ground clearly.

 

I am currently using the trial and also tried FS Global Weather which is also available on trial. That handled low visibility much better by inserting the low visibility much earlier and more gradually.

 

The thing is, in all other respects Active Sky Next wins hands down so I am hoping there is some setting I can adjust so low vis is depicted earlier and not suddenly at low altitude. In all the comments and reviews I have not seen this issue mentioned before.

I would have posted this in the Hifi forums, where they can actually read your experience and may choose to implement a new feature for SP1.

I have not had this happen. I also suggest posting at www.hifitechinc.com to see what they can do re your settings.

Actually this issue have been discussed several times here and there, I 'm afraid it is a flaw and cannot be remedied through settings.

ASN has a visibility setting called 'Default haze layer'. By default it is set to be disabled but you can try and enable that option, set historic weather (to re-create the low vis) and see if that makes a difference.

ASN has a few quirks but I think most of them are due to P3D and not ASN and I also doubt if ASN can do something about it. I have to say ASN has more quirks than I expected because the blah blah makes it sound it's almost perfect but I still get sudden changes in weather, clouds in the distance showing up in front of clouds nearby, a wall of fog with a very hard edge, etc. But as you said, ASN wins hands down in all other respects (historic weather that's loaded automatically based on the time in the sim, automatic loading of flight plan, audio ATIS for departure, enroute and destination, settings for maximum wind, etc.) so I am very happy with my purchase. (I already owned OpusFSX but it never clicked with me, obviously because it doesn't have all the things I just mentioned but also because it comes with too many extra's and cryptic option I don't need and want and I just never liked the interface and the too frequent updates (yeah, I'm crazy LOL).

I've noticed the wall of fog with the very hard edges too but other than that - ASN - wow. I just had the most immersive flight I've had in years, I'm talking a "Mitch flight" here. Spent a few hours gettin' my Orbx on earlier and finally did KBZN - KWYS - KJAC in the Metroliner (so far - sim's still running, so is ASN). Using historical weather for 8/25/14, departed KBZN at 6:45 AM local (sim time). KJAC was badly socked in, I slipped in on the VOR first from about 30 nm North, then the ILS when it came into range. Popped out at about 200' AGL and greased 'er on. The clouds hanging in the Tetons inbound from 20,000' were flippin spectacular, something I've never seen in the sim before! A definite positive of ASN!

 

Another tank o' gas and I'm back on the road again! Gotta hit Idaho Falls before I call it a night!

Thanks for the replies. I posted on the developer website and they quickly replied. It seems the volumetric fog is global and it means the problem can occur if one area close to the destination has good visibility but the destination does not. The volumetric fog can then appear suddenly. They are looking at solutions and also seeing if LM can resolve this.
