Paul, Per your advice I obtained the free lasso utility. I have the GTN-750 set to high priority using 4 cores. FSX is set for "normal" priority for the time being. An added bonus is the response time (the time it takes the GTN to boot up when I load the aircraft, and the time it takes to change screens in the GTN-750 when using the mouse to change screens in the GTN) has improved. Thanks much for the advice.

Thanks all for the information. I wasn't aware of process lasso. I'll give it a try. I have a quad-core cpu (Intel i5-6500).

90% of my flights in FSX are with the A2A C182 Skylane and the Flysimware Lear 35, which both have the Flight 1 GTN-750 installed. About a month ago, I began to have significant stuttering problems with FSX where, previously, this was not an issue other than the occasional microstutter. Despite the stuttering, I was consistently getting 40-50 fps and higher but the stutters continued to get worse. I tried numerous fixes, e.g.; updating my video card driver(Nvidia GTX 750 ti) and making some changes in my fsx.cfg, At one point I thought Active Sky Next (ASN) might be the cause of the problem, but this turned out not to be the case when I did a flight without ASN and still had the stuttering. Then I recalled that the stuttering began around the same time that I had to reinstall the GTN-750 after it failed to display in the panels of the two aircraft. (I never determined what caused this but after reinstalling it, it worked properly) Today after attempting another flight out of PAJN (Juneau, AK) in the Lear 35, and getting severe stuttering as soon as I began taxiiing to the runway, I decided to uninstall the GTN-750. ( I backed up the installation file so I can reinstall it at any time). Without the GTN-750 in my panel, the flight was stutter-free and smooth as silk. I would really like to continue use the GTN so I'm wondering if anyone else has, or had, the same issue and can provide some information or recommend an alternative to the GTN-750.. Thanks. Bob .

Problem resolved. When I initially installed the Cherokee, the Aircraft Configurator was not in the Tools Folder. So, I assumed that it simply wasn't available for my version of FSX (boxed version). Yesterday, I posted this issue on the A2A Cherokke forum and explained the problem. Nick, who I believe is the forum moderator, advised that an update file was available and recommended that I download and install it, which I did this morning. The Aircraft Configurator, along with the Input Configurator and a file called "ac.cfg" are now in the Tools folder. I just activated the GTN 750 in the Cherokee cockpit. Bob

Well after delving into this a little more, it appears that I'm out of luck because the Cherokee 180 for the FSX boxed version does not have the "airport configurator" utility, as far as I can tell. It does not appear in the appropriate A2A folder or any sub-folders. It does have an "input configurator" but this utility won't accomplish what my original post was addressing. So I have to use the 2d version of the GTN 750 unless I upgrade to the FSX Steam version or P3d.

Thank you Bert.

Thanks for the information. I took a look at the Aircraft Configurator but, to be honest, I can't figure out how I would use it to integrate the GTN 750 into the Cherokee VC. Is there a tutorial that is available?

I purchased the A2A cherokee 180 and installed the Flight 1 GTN 750 into the aircraft but...it only appears as a movable 2D panel in the cherokee VC. I want to integrate the GTN 750 into the 3d Cherokee panel. I know this can be done as I've seen it in a youtube video. The Cherokee manual provided by A2A does not discuss this matter. Does anyone know how this can be accomplished and/or is there a tutorial that will provide this informaton? Thanks for any information. Bob

I think I found a solution which has worked so far. At the beginning of the flight, sitting on the tarmac, getting the A/C ready for my flight and starting up the engines etc., I place the taxi/landing lights switch in the "taxi-light" (mid-range) position and leave it there. I do this whether or not my flight begins in daylight. For the remainder of the flight until the landing phase, I keep the light-switch in the taxi-light position. Then, if I land in dark conditions, (late-evening/night), I place the switch in the far-up (landing lights on) position to turn on the landing lights as I approach the airport. When I turn off the runway, I switch to the taxi-lights. Using this procedure, the landing and taxi lights now illuminate the ground in front of the aircraft. So the key point here, which has resolved my issue, is to turn on the taxi light-switch at the very beginning of the flight (even when it's mid-day) and keep it there, rather than wait until the landing phase to turn on the landing lights (if needed).

Bob, Tks for reply. I'm using the boxed version of FSX. Is there a "dynamic lighting" feature? I know Prepar3d has this. I did have the landing/taxi light switch located on the panel in the "on" position for taxi and landing lights. Well, I'll keep working on it. Will post back if I solve the issue.

I have updated my Learjet 35 to the latest version, 3.0. I have noticed that the taxi and landing lights, from the cockpit view, are not illuminating the ground in front of the aircraft, although in spot view I can see see that the lights are on. I was not having this issue in prior versions of the lear. I don't know if this is a specific problem with v3.0 or if there may be something I may be overlooking. Any advice appreciated. Thanks. Bob

Matthias, Thanks very much for that very helpful information. Thinking back to my last flight with the Lear, I'm almost certain that the reason I assumed I was not getting fuel from the tip tanks to the wing tanks was that I failed to insure that the jet pumps were on. Although, as you indicate in another post, gravity feeds the fuel from the tips initially and the jet pumps only come into play when the fuel in the tips goes to less than about 50 percent. I definitely will monitor this on my next flight. As you suggest, I always start FSX with a previously saved flight specifically, the stock Cessna 172 sitting at my "home" airport, KCMA, in a "cold and dark" start situation. Thanks again, Bob

Thanks. Should the transfer switch be in the neutral position? Because unlike previous versions, I'm not seeing fuel being transferred to the wing tanks from the tip tanks. The fuel runs out in the wings and then I have to transfer from the fuselage. I'm probably not doing something correctly.

With version 2.6, I'm having a problem with how fuel is sent from the tip tanks to the wing tanks. I believe that in the real aircraft, fuel flows first from the tip tanks to the wing tanks and, when that is exhausted, fuel can be transferred to the wing tanks from the fuselage. This is the way it seemed to work before version 2.6. Now, I'm not seeing any fuel flow from the tip tanks to the wing tanks. According to the 2.6 update at the flysmware website: 1. "'tip tanks are now externanl (sic) in the cfg. file so fuel never burns from the tip tanks" 2. " Fuel valve now transfers tip tanks to wing tanks when tip tanks are 50%". First question. Where is the valve that transfers the fuel from the tip tanks to the wing tanks? (I thought this was an automatic process). The only related item I can locate is the switch on the console which transfers fuel from the fuselage to the wings but has no effect on transferring fuel from the tip tanks. 2nd question. The second statement does not seem to make sense. Should it not say, "Fuel valve now transfers tip tanks to wing tanks when WING tanks are below 50%. Thanks to anyone who can answer and clarify this for me. Bob

If you want a payware bizjet where everything actually works, including the autopilot, get my personal favorite, the Flysimware Learjet 35A. If you do get it, I highly recommend also purchasing the Flight 1 Garmin GTN 750.
