Joan Alonso 64 Posted January 9, 2019 Share Posted January 9, 2019 Hi, I open a new topic regarding this because this topic got lost within other managed speed topics time ago, I can not remember which one. So, some updates ago, the FLEX temp on IAE was working fine as the CFM does with data from http://wabpro.cz Now, numbers higher than the default MCDU flex temp leads the aircraft not to apply the correct thrust but a much lower thrust. (only IAE) If I recall correctly, the problem exists since the IAE climb profile/drag was changed. Are there any news on this? Thank you Link to comment Share on other sites More sharing options...
Deputy Sheriffs Secondator 643 Posted January 9, 2019 Deputy Sheriffs Share Posted January 9, 2019 Hello Joan, Can you give me some more information? What value is it showing to you on top right corner of upper ECAM and what value is the flex thrust giving you? I just checked this on A320 IAE by manually selecting a higher flex temperature than what the FMC automatically gave me after inserting flap value and there seemed to be no problem at all.

Hi, LEBL/LEMD 29º TAT 1015 QNH Wind: 180/12 TOW: 64100 CI: 20 Departure runway 25L / SENI3F to SENIA Default FMC data (FLAPS 1): FLEX: 64º (ECAM showing 64º 1,284) 124 133 134 Data form wabpro (FLAPS 1): FLEX: 70º (ECAM showing 70º 1,255) 144 144 145 It seems underpowered with the non default data, barely takes off at the end of the runway and after liftoff the aircraft can not climb at all. Although it's not a great difference between two given FLEX temps. Link to comment Share on other sites More sharing options...
