There has been considerable debate over the speed and power the A340s possess and many attribute this to the underpowered engines. A couple weeks ago, I noticed some posts which stated that Airbus was thinking of upgrading the engines for the A340s due to customer demand. One person had noted that this decision was made before Sabena's recent airbus order and that their A340s will have the brand new upgraded engines. In addition, I believe the engines were still CFM56's but with a slightly higher thrust rating. I was wondering if this was true and what Airbus is actually doing with the issue... I would love some information please.
