GaryMcCl 17 Posted March 15, 2021 Share Posted March 15, 2021 This is very frustrating because it's happening on every take off. I ensure that i don't point the nose up when I leave the runway too much (on the A321 i limit it to 15°). I leave the speed as soon as I get to, which works fine. The problem, however, is that as soon as I turn the AP on, the engines go right down and I end up with a nose pointing up and a alert. Can anyone explain what order I should do, or point me to the right page/documentation? Thanks, Gaz Link to comment Share on other sites More sharing options...
Deputy Sheriffs masterhawk 799 Posted March 16, 2021 Deputy Sheriffs Share Posted March 16, 2021 You have all configured properly? Weights at INIT B and also Vspeeds at PERF TO page? Aircraft is not overloaded? Link to comment Share on other sites More sharing options...

Deputy Sheriffs Hanse 216 Posted March 17, 2021 Deputy Sheriffs Share Posted March 17, 2021 Hi Gaz, looking at the screenshots and the values stated in the INIT B page (ZFW/ZFWCG = 46.9/26.0) as well as in the PERF TO page (/THS = DN2.3) it seems quite normal what happens because those values seem to be completely wrong. Where did you get those values from? Also the BLOCK FUEL of 2.4 for a flight from EGPH to EGKK just covers the trip fuel and does not consider any other parameter like Alternate Destination, Holding, Contingency as well as Final Reserve. Please end us a screenshot of the Load-/Fuelpanner for that flight and I am able to tell you what might be wrong in your handling.

GaryMcCl 17 Posted March 17, 2021 Author Share Posted March 17, 2021 Hi @Hanse I appreciate you looking at this. The FlightPlanner is still showing the flight: Please login to display this image. REALLY hope that helps for any advise. Gaz Link to comment Share on other sites More sharing options...
Deputy Sheriffs mopperle 4162 Posted March 17, 2021 Deputy Sheriffs Share Posted March 17, 2021 I would say your aircraft is not well balanced. Simply avoid any red values on the left side, in your case TOW %MAC. Link to comment Share on other sites More sharing options...
GaryMcCl 17 Posted March 17, 2021 Author Share Posted March 17, 2021 Does that mean I am carrying too much? The balance seems to be corrected when I press the RESET button near Adjust CoG. When I do so, it changes to this: Please login to display this image. But how do I keep it like that.

Deputy Sheriffs mopperle 4162 Posted March 17, 2021 Deputy Sheriffs Share Posted March 17, 2021 I will check this. But btw. under "advanced parameters" I see some sttings making no sense at all: - taxi time 60 miniutes, really? An airline taxiing around 60 min. wuld be commercially dead very soon - alternate distance 20 nm ??? Well, that would be just on the other side of the airport - 80kg final reserve? That's nothing, just enough to run the APU for afew minutes. Link to comment Share on other sites More sharing options...

That's nothing, just enough to run the APU for afew minutes. I understand, but I normally wouldn't have to change any of those settings. I that's what the tool was for. I have to say, I'm not sure. I'm guessing in some circumstances you run out of fuel because of the weather? Maybe (i don't know if it's better), but use SimBrief instead?

Deputy Sheriffs masterhawk 799 Posted March 18, 2021 Deputy Sheriffs Share Posted March 18, 2021 You can use the slider to adjust the CG. Until it’s green (around 26%). That’s the optimal value. Black values will also be ok. But no red ones. Then press generate loadsheet and don’t forget to import it in MCDU 3. Link to comment Share on other sites More sharing options...

Then press generate loadsheet and don’t forget to import it in MCDU 3 I always press the RESET button to make sure those CG values are correct, then I load it into MCDU3. If I then open the Flight Planner I get to see that it has RESET the CG is not black, it's red. So, when I had set it correctly (so it's correct, and black). It's like it's not doing what you say: if I use the fuel planner, it ignores what's on my screen and saves the red (incorrect) figure. Link to comment Share on other sites More sharing options...

Rest will reset the cg slider to the default position that’s all. The default position is not very accurate. I suggest this procedure: 1. Set pax and cargo to desired ZFW 2. Enter departure/arrival to set the fuel 3. cross check all weights are still green 4. use slider to adjust CG to black (optimal green 26%) values 5.

Deputy Sheriffs Hanse 216 Posted March 19, 2021 Deputy Sheriffs Share Posted March 19, 2021 What do you mean by "tellimg me, I am low on fuel". Who is telling you that resp. where do you get this information from or based on which information you assume something like that? Everything seems to be correct. Looking at the screenshot your fuel just before T/D is 2.940 kg. For descent I assume you will need maybe add. 340 kg so that your FOB after landing will be app. at 2.600 kg. Or does the value EFOB on the MCDU FUEL PRED page states something different...... Link to comment Share on other sites More sharing options...
GaryMcCl 17 Posted March 20, 2021 Author Share Posted March 20, 2021 @Hanse, if you look at the entry I last made, there is a screenshot of the cockpit saying that it's fuel is low. That is based on me making sure that I have correctly made entries on the FlightPlanner. So - the flight planner didn't give me the correct data, despite it saying it had.

Deputy Sheriffs Hanse 216 Posted March 20, 2021 Deputy Sheriffs Share Posted March 20, 2021 Gary, the message states "Fuel below 3 T" (below 3.000 kg) and does not state that you are low on fuel. It is just an information and nothing more. If you look into the MCDU FUEL PRED page and if it displays a positive EFOB (normally around 2 T) then everything will be fine.......
