I bought this product a while back and just started using it on win7 64bit FS9. I created a flight plan in the FMGC along with all of the mandatory information however I prefer to fly in selected mode for full FCU control.

 

The issue I am having is that after take off the aircraft starts climbing normally and eventually uncontrollably even though the autopilot is set with a v/s of 2500 fpm. The aircraft has a hard time accelerating even though it is on selected speed at 230 for example and I am forced to bring the throttle detent to TOGA.

 

Another issue I am having is when I reach close to 30,000 ft. the CL detent can not hold my target speed on the autopilot, the speed just hovers below the target speed on the FCU. Could this be because the nose pitch is too high? I have been setting the cruise altitude and flext temp in the FMGC.

 

Anyone else have this issue?

Check your FMA before takeoff or before engaging the autopilot. "CLB" and "NAV" modes must be armed.

 

For the second issue, I have no idea. Maybe you should check the optimal crusing altitude and if your gross weight isn't too high.

 

On the beginning I found this aircraft very tricky. You have to get used to its logics.

Thanks for the response and well noted. Another issue I as was having is after take off I pitch up 15 and the aircraft wouldn't gain speed on the CL detent, it would stay at 185 unless I used TOGA. I noticed that I set a cost index of 15 and Flex temp of 22. I have since changed this to 30 and 50 respectively. I can't seem to find an explanation on this but could it possible that I was too low of a cost index and Flex temp? therefore the engines were not giving enough power?

Climb thrust should be set only at 800' or 1500' AGL, depending on the procedure. I'm not that familiar with this aircraft to state which is the correct pitch for climb out, but if your weight is correct, gears are up and you're mantaining V2+10 to V2+20, you shouldn't care about pitch.

 

Cost index doesn't affect take-off or climb thrust. It's used to calculate climb, cruise and descent speeds. And Flex temp is irrelevant unless you select the FLX detent. "Flex" is how airbus call their thrust derating method.

I set my climb thrust to 1500' as in the FMGC. I also now fly in manged mode and the fmgc maintains 250 below 1000' and accelerates to 280 for climb. On more than one occasion at around 23000' the aircraft just disregards the FD and goes into a steep climb, speed drops then it descends rapidly. I recover in TOGA and disengage AP and FD and reengage and fully recover. My GW is 150K lbs. My pitch is 05 down and the weather and there is a cross wind of 26 kts. My target altitude is 35K.

 

Could this be a bug with the app or can the wind change in FS9 be that significant to throw the aircraft off by that much?????

 

Could this be the 50 degree flex temp I entered which is giving too little CL EPR? I am at 28K' right now and have a 1.476 EPR for CL.

Check if your GW isn't greater than the maximum take-off weight. 150000lbs is almost equal MTOW (or even greater, depending on the variant).

 

During approach, you'll have to monitor if the autopilot is actually following the glide slope. I've seen more than once the autopilot flying the aircraft below the glide path. If that happens, disengage the AP and fly it manually. About the winds, I'm not sure. I don't use FS9, but I think it may happen if you're using default weather.

 

Flex affects take-off thrust only, but if you are worring about it, why don't you leave it blank?

 

Do use any other add-on aircraft? I've learned that you have to lower you expectations. It just doesn't compare to PMDG or other developers' quality.

According to the Specs chart, the A320's MTOW is 162K lbs. MY GW is always below that by at least 10K lbs.

 

I am confused about something concerning Flex. I typically use TOGA for take off anyway but if Flex is only for take off than how come my CL EPR is limited?

Climb thrust is usually less than take-off thrust in any aircraft. Flex is used to reduce engine wear and noise during take-off roll and initial climb. After you reduce the thrust to CL detent, it's not used any longer. In Boeing aircrafts you can derate climb thrust as well, but I don't think you can do that in Airbusses.

 

CL/CLB thrust is always limited. If you use TOGA thrust for too long, your engines will probably overheat.
