This Topic is not really related to the thread of MSN141.
Could you please switch topoic to the thread of MSN65 or MSN71?

We can only say that at this moment of time, these two frames are been reworked towards potential customers like French Bee and Virgin Atlantic. From past experience between Airbus and Virgin Atlantic, they have an “understanding” - after VS received a few frames from Airbus and happy with their performance, Airbus refurbish and rework on prototype frames (on all four A340-300 and A340-600 that I’ve mentioned before) accordingly to VS’ standard configuration. Then the frames will be financed through Airbus Finance on a 10 or 12 years lease to Virgin (and they’ve never extended lease on these prototype frames). So they’ve never shown as a firm order for Virgin on the book. |

dear friends, I am writing a book and have a question about airplane's power reduction after takeoff. Here is a short video of Delta's A350-900 taking off and if you listen for a couple of seconds, there is a distinct change in engine's sound: I always thought that it means engine power reduction upon reaching the cruising altitude, but seeing the airplane do it shortly after takeoff it must mean something else? I need the exact name of the process taking place as I don't want to look foolish writing nonsense  Anyway, as the story goes, my character who was really afraid to fly, noticed this sound during the takeoff and was frightened that they gonna crash... I thank you all in advance for helping me on this |

Climb almost always uses less thrust than at take off, no? I've seen this with pretty much every take off. Here you can see the pilot pulling back the thrust a few moments after take off. foreigner , good luck with your book! Edit: You'll find some good answers in this a.net thread. www.airliners.net/forum/viewtopic.php?f=5&t=1403959 |

an average person would not know that this is "derated climb", so I cannot use it even if it is true. The question is if it is reasonable to call it "reduction of power", or, perhaps, "loss of power" in the eyes of a scared passenger.
thoughts?

"Reduction of power/thrust" would be most appropriate in layman's terms. "loss of power" would seem signify something abnormal. You can see the following thrust lever of an A330. The CL is for Climb, which is less than TO/GA.  karlenepetitt.blogspot.com/2011/04/a330-thrust-levers.html (A good resource for understanding some of the Airbus thrust lever basics.) |
