Hello,

 

I'm just starting to learn the NGX but I have ran into a problem. After setting up the plane as per the instructions in Tutorial #1, I slowly moved the throttles to 40% N1, then clicked TOGA. In about 3 seconds, the autothrottle disconnects. I've done the tutorial 1 twice and A/T disconnected during takeoff on both occasions.

 

I have a Saitek Throttle Quandrant and I calibrate it using FSUIPC.

 

Am I doing something wrong? What's seems to be the cause of this problem?

 

Many thanks in advance!

 

Nick

Unfortunately this is common, you have to setup as separate way, there are already many thread on it.

Throttle must setup in FSX.

Interesting seeing how I have mine set up just fine through FSUIPC...

Sure- but that's dealing with multiple throttles with separate axes. I'm referencing a single throttle setup- like the Saitek quadrant and my flight stick.

Just tried Tutorial #1 again with just 1 axis set for all throttles. A/T doesn't disconnect but doesn't advance the throttle to takeoff speed after clicking TOGA. It stayed at 49% N1 and wouldn't go up. The tutorial says to establish 40% N1 which I did (and stayed at 40% for about 5 secs), but for some weird reason TOGA doesn't kick in completely.

what FMA says?

Maybe attach a picture and we can see if it's a config error. Remember that you do not arm spoilers, and you must have both FD's on.

You need to make sure your trim is in the correct position on your yoke or stick move it around when trying to hit AP switch this is the problem well not actually a problem just something you need to be aware of try it you'll like it, over & out.

Thanks for the replies.

 

I followed the tutorial to the letter and both FD were on. Trim was set correctly and I double-checked it as well. Spoilers were not armed.

 

I'll try and do it again and take pictures if something weird happens.

Tried the tutorial again and I was able to complete it. One strange thing was that on final approach with GS locked I didn't see "LAND 3" in PFD. Instead, SINGLE CH popped up. But the autoland went without a hitch. I just need to be more careful following the tutorial to avoid any mistakes.

 

I found a imperfect way to bypass the FSUIPC autothrottle problem. I set up the axis in FSX and calibrate them in FSUIPC. Then on takeoff, I use the keyboard (F3) to advance the throttle to 40% N1. The A/T didn't complain. However, I'm sure there will be instances when the above won't work.

 

Thanks again for all your help!

Nick when you find what works be it software or hardware and combination of both stick with it sounds like you are getting the hang of it well done.

It would be because you aren't in a dual channel mode where both autopilots are active for the approach (Or you you haven't gotten to about 1500ft agl). You must the nav frequency set in both nav radios, as well as the course in both course selectors. Then you will be able to perform a dual channel approach and autoland.

 

Now, if your aircraft is fail-passive, then you can conduct an autoland and rollout where it will be able to maintain the centerline until disconnect. This is an expensive option in real-world, so very few carriers have it installed.

that was a great post. I remember reading it some time ago and passed it by, thinking my throttles were ok. After re reading it, I deleted the joystick calibrations in FSUIPC and set my thrust lever axes as throttle 1 set and throttle 2 set, sending to FS for calibrations (as per Jason's post). Auto throttle seems to be rock steady now, no more disconnects. I can also take advantage of the blue arc as well as move my thrust levers without having the AT disconnect. Glad this topic was revisited. Thanks.

My throttle issues disappeared when I reverted to setting them up entirely within FSUIPC.
