jsolecki 0 Posted November 11, 2014 Share Posted November 11, 2014 I just tried yesterday new A320. Very nice plane but just a small problem on left MCDU : First flight was made with following flightplan : LFLS27 WS VNE MEN GAI AGN AUCHE VAKPI LFBT20 at FL320 in Clear weather conditions At the beginning of the flight MCDU showed T/C at 18 Nm BEFORE MEN During Climb, T/C was continuesly moving back and just before reaching FL 320, MCDU showed T/C at 58 NM AFTER MEN. Really FL320 was reached at 34Nm BEFORE MEN Flight was entirely in managed mode and T/C was correct on ND. All the flight was good : it seems to be a problem on MCDU Same effect on both Sims : P3Dv2.4 and FSX I apologize for my english (school is very far ) Best regards Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted November 11, 2014 Deputy Sheriffs Share Posted November 11, 2014 Don't apologize for your english, it is very good. And on top of that you gave us a description of the problem that really helps us to understand what you mean and see in the sim.. I think I know what the problem is here but I will first forward it to the dev. Thanks Link to comment Share on other sites More sharing options...
jsolecki 0 Posted November 20, 2014 Author Share Posted November 20, 2014 Sorry but new version 1.1 seems to have the same problem. I just loaded it this afternoon and install after uninstalling the old one and in the same flight and conditions of my precedent post the effect was exactly the same : T/C is not correctly displayed on the MCDU and moves back continuesly during Climb after a short time of flight. Perhaps developpers have not looked at this problem for version 1.1 ? Best regards J-C Solecki Link to comment Share on other sites More sharing options...
ubersu 23 Posted November 20, 2014 Share Posted November 20, 2014 Assuming T/C is computed during climb it is always going to move in response to winds aloft and air temperature. Turn off all weather and wind and see if the T/C indicator shifts around... DJ Link to comment Share on other sites More sharing options...
jsolecki 0 Posted November 20, 2014 Author Share Posted November 20, 2014 All my tests were done with Clear weather conditions that's to say with no wind and standard temperature. T/C is well displayed on ND but completely false on the MCDU during Climb. JCS Link to comment Share on other sites More sharing options...
Joshua Che. 1601 Posted November 21, 2014 Share Posted November 21, 2014 This is a known very low priority issue. The prediction system was optimized around descends and no attention was paid to climb (climb predicting is of not much use). It is highly unlikely it will be changed anytime soon Link to comment Share on other sites More sharing options...
Don Lee 6 Posted November 22, 2014 Share Posted November 22, 2014 I had this problem too, it caused that I reached T/D before T/C, but in the beginning it saw a long way of my cruise space, optimized cruise alt was FL370 but I could only climb to FL280.

Hi Don, you should not primarily rely on this calculation. If your flight is short, it either doesn't make sense or is simply not possible to reach such a high flight level. Do this planning beforehand and will not have such unwanted surprises. Link to comment Share on other sites More sharing options...
PikalaxALT 19 Posted November 24, 2014 Share Posted November 24, 2014 I had this problem too, it caused that I reached T/D before T/C, but in the beginning it saw a long way of my cruise space, optimized cruise alt was FL370 but I could only climb to FL280. Don, I had a very similar problem recently in the NGX. I had missed my after takeoff checklist, and when I noticed that my climb rate was slow, I eventually realized that my gear was still extended. Whoops! Anyway, make sure that your airbus is in clean configuration: gear up no lights, flaps zero, spoilers retracted. Link to comment Share on other sites More sharing options...
Don Lee 6 Posted November 24, 2014 Share Posted November 24, 2014 It's not going to happen to me as my VA will give me a penalty if I don't put the gear up when I get positive climb rate and lock it below 10,000ft. Link to comment Share on other sites More sharing options...
