Airbus339 129 Posted February 2, 2015 Share Posted February 2, 2015 Hello, I've just tested the latest version of the A319 IAE (didn't test the A320 & A321) and I found the initial climb performance are still a bit sluggish when using high flex temperature. For example, I tried a Flex 67 t/o from Gatwick with a 58T A319 and after lift off wasn't able to climb at more than 1200FPM. Then I tried a flex 57 t/o at AMS under the same weight and weather conditions and situation was better with 1800/2000 FPM after lift off. Any thoughts about this?

lucikam 4 Posted February 22, 2015 Share Posted February 22, 2015 I agree. The climb performance of the IAE variant of the A320 is very poor compared to the CFM. I noticed it from the beginning and I have completed several flights on the same route [LHBP-EDDM] with both the Lufthansa [CFM] and the Wizzair [iAE] model, same light load, similar weather. With no exception I found the same: it takes significantly longer for the IAE to reach FL360-380 than the CFM one. For the IAE it often takes 32-35 minutes to reach it. While there can be minor differences performance wise, I doubt that the IAE is this much weaker. Looking around in the forums I also found that many people noticed that same.

In my system both IAE and CFM reach final FL in approximately the same time. What I was saying is that the immediate climb after t/o, in the IAE, is extremely sluggish if using low flex settings Link to comment Share on other sites More sharing options...
wiss 2 Posted February 22, 2015 Share Posted February 22, 2015 I have the same issue, but the climb rate becomes normal once I retract the flaps. Could be the flaps for the A319 IAE make too much drag? Link to comment Share on other sites More sharing options...

craigy 20 Posted March 17, 2015 Share Posted March 17, 2015 Hi I have just tried to depart 3 times from EGKK in A319 IAE. The proposed flex was 57 but I reduced it to 40 and the aircraft fails to climb and crashes. I don't have problems with the CFM versions. This has become very frustrating.

craigy 20 Posted March 18, 2015 Share Posted March 18, 2015 Well I did a clean install and the IAE version of the A319 just doesn't want to fly. I'll not waste any more time with it and stick it in the hanger until SP3 is released. Until then will stick with the CFM version that works well.Sorry but there is something wrong with the IAE engine modelling by the way it works on my computer anyway.

airone 18 Posted March 27, 2015 Share Posted March 27, 2015 I agree with all of you, guys. Initian climb perfomance of IAE models still very poor Link to comment Share on other sites More sharing options...
Joshua Che. 1601 Posted March 27, 2015 Share Posted March 27, 2015 The A319 IAE in particular is being looked into with new data. The other "performance" claims will NOT be looked into as explained before in other topics. Use the search function. Link to comment Share on other sites More sharing options...
