FSX-MS ActiveSky 2016 Aircraft falling out of sky during cruise?

[Airplane_21]

I'm really hoping a fellow flight simmer would be able to shed light on what's going on.

When ascending to cruise altitude/flying at cruise altitude, if I attempt to momentarily change simulator windows (as in, pressing ALT+ENT to minimize FSX or enter the map view mode by selecting World > Map), on entering back into the sim my aircraft drops out of the sky because my airspeed plunges to 0 KTS.

I thought maybe Ultimate Ground X or AISmooth addon(s) were causing issues, so I disabled both of them and only ran AS16. Issue still continued.

I thought maybe increasing the simulation speed to 4x is causing issues, so I flew in normal simulation speed to cruise altitude. Issue still continued.

Event though I always go through pre-flight checklists before take off, I double checked that my pitot heat/anti-ice systems were on, and sure enough they were. I confirmed this on various aircraft, including the default A321/B737/B747 and even my payware PMDG 777 and 747.  Issue continued!

I am now quite simply stumped as to what is causing my aircraft to suddenly just stall out of the sky and drop the airspeed to 0KTS out of nowhere. My aircraft just falls out of the sky and crashes!

Could anyone please help me figure out what is going on. 😞

Why is Active Sky 2016 quoted in your title?   Have you shown it to be related to the problem?

I would agree with John B - I think your title is perhaps unintentionally misleading!

I have used AS2016 for many years with many different aircraft and have never come across an issue like this related to it. Although I would be very surprised if this is anything to do with Active Sky, one way to check this would be to fly the scenarios in question with AS2016 deactivated/uninstalled and try to replicate the problem.

The only time I have ever encountered anything like this in the past was once or twice when I reloaded an autosaved flight following an FSX crash to desktop and the autosaved flight was in midair with AP/FMC engaged when the CTD occurred.

Of course I have, I've referenced AS16 all throughout my post. My aircraft speed drops to 0KTS when ActiveSky 2016 is being used for real world weather at cruise altitude. Apologies if my post was unclear, but yes my whole issue pertains to AS16!

Like scianoir, I have used AS16 extensively in the past without any issues. I would be surprised if that was the sole cause of your problem.  You have not actually said if you tested the same situation without starting AS16. If so, what result.

If the problem does not occur when your other software is running, and with just AS16 shut down, it's possible you have a corrupt download.

In that case start by completely uninstalling your current version of AS16. Try running the same flights, with and without your other addon software, and see what happens.

Make a fresh download of AS16 and install that. See what happens.

It's a good idea, after each of these of these changes to exit FSX and restart the pc, so each test gets off to a clean start.

After the above processes, if the problem persists only when using AS16, I suggest raising a ticket with HiFiSim. They are experts in this field

Thanks John, I appreciate the insight.

I'll give the trial-and-testing a go and see what comes about.

Which aircraft? Al or just one in particular? And I'd love to see if AS16 is in fact the issue as like many here mention I have not had issues with AS16 either. NOt saying it can't be an issue, but it's unlikely to do so. I think it's gauge or something else with the aircraft. What you say is that when the cockpit losses focus the airspeed drops. There's a reason for that.

Some feedback would be good if only to satisfy my curiosity!
