Zamir 0 Report post Posted March 19, 2011 (edited) Hello,can I know what type of Engine does the AirAsia A320 operate?Sometimes I find that AirAsia operate all CFM engines Edited March 19, 2011 by Zamir Share this post Link to post Share on other sites
Gavin Andrew David 6 Report post Posted March 19, 2011 They all run on CFM's none run on IAE I think its CFM56 5B4 Share this post Link to post Share on other sites
Walter Sim 1 Report post Posted March 19, 2011 Think the first few A320s are 5B4's, then the bulk of them have the 5B6 which has less thrust Share this post Link to post Share on other sites
flee 5 Report post Posted March 20, 2011 Aircraft reggos 9M-AFA to 9M-AFF (A320-214) use the CFM56-5B4/P. Aircraft delivered since 9M-AFG (A320-216) have the CFM56-5B6/P. More information on the CFM56 engine variants here Share this post Link to post Share on other sites

More information on the CFM56 engine variants here 9M-AFA is now a -5B6. Anyways not much of a problem as the -5B4 engines with higher thrust ratings (27k) have been reduced to an all fleet rating of 23.5k pounds. Share this post Link to post Share on other sites
Radzi 2 Report post Posted March 20, 2011 Can the thrust rating of the 5B4 be increased by the flight crew to the original 27k rating if necessary? In comparison MH B738 CFM56 engines can be rated at 26, 24 or 22k as needed, just by some selection on the FMC, depending on the need. Share this post Link to post Share on other sites
Gavin Andrew David 6 Report post Posted March 20, 2011 Any reason as to why they changed to 5B6 ? Share this post Link to post Share on other sites
Y. J. Foo 0 Report post Posted March 20, 2011 Are there benefits from the point of fuel consumption and/or MX etc by reducing thrust rating? Share this post Link to post Share on other sites
Radzi 2 Report post Posted March 20, 2011 Reduced thrust = less maintenance = longer engine life. Share this post Link to post Share on other sites

Capt, I don't think they can select anything above the 23.5 as it has already been pin programmed to provide a max of 23.5. I will check and revert to you when I have more information.

I will check and revert to you when I have more information. if you say it is pin programmed then it is just as the same as the 737 classic where there's no such thing as EEC and HMU like 737 NG, only MEC and PMC and a direct thrust control cable from the throttle lever to the MEC.

Sorry for the choice of words, but I believe it was already programmed in the ECU. I stand corrected anyways. Share this post Link to post Share on other sites

Capt,unlike Boeings,the Airbus planes cant derate their engines,but they use derate thrust for takeoff,which they call "Flex" take off(using an assume temp higher than ambient OAT"provided certain criterias are met.The A330 NG can derate their thrust setting to either D1 or D2 depending on company SOP.Having flown the classic B737,A320 and now A330 NG,the Airbus planes have done a lot of improvements to their airplanes.The engines are the same as for the 5B4 or 5B6,its a computer setting which cannot be reset by the flight crew that changes the engine rating.

Ahmad M 1 Report post Posted March 21, 2011 On MH's A330-200 you can do both De-rate and Flex for take off. Share this post Link to post Share on other sites
