Jespersson 17 Posted October 25, 2018 Share Posted October 25, 2018 Hi! I have recognised quite significant differences in the take-off and climb performance of the different engine options for the A320. So far I have not flown both engine versions of the A319 or 321 so I can't say for sure that the same applies to them. But I did some testing and got these results. I know that the engines are slightly weaker on the IAE but the climb rate and take-off distance is quite significantly different. Of course I don't know all the facts of the buses but the IAE seems to climb like an A340-300 at times (which we all know is not a good thing ) so I'd love some input on this from someone who really know how the buses are supposed to behave. For testing purposes I used clear weather and no winds. Let me know if you need any additional info.

Meyerflyer 154 Posted October 25, 2018 Share Posted October 25, 2018 Hello, you may have a look on this thread. Did you modify the Flex temp for takeoff or did you leave it? If you took another flex temp setting, please try not changing it and post your results here. That would be an interesting information. http://forum.aerosoft.com/index.php?/topic/140250-takeoff-thrust-with-higher-flex-temp-is-lower-than-climb-thrust/ Link to comment Share on other sites More sharing options...
