Am I biased?

In the airliners.net forum there is a discussion about my last blog entry and that I am biased towards Airbus and the GTF and against Boeing and GE/CFM.

Am I? Well, yes and no! I am partially biased - but only by knowledge (where applicable). After all I am an engineer always looking for the best technical solution.
And I am not biased - I have absolutely nothing against the B737MAX itself. In fact, if you look at a posts from June 2011  you will see that I was sceptical that Boeing will do a NSA (New Small Aircraft) but was in favor of the reengining. I am very sure that Boeing will build a very capable aircraft. If the fuel burn improvement comes out as advertised by Boeing, the range capability of the B737MAX-8 will be for sure better than that of the A320 family. The article from Aspire Aviation points it out, although with the same payload as the A320 (150pax) the B737MAX-8 range will be boosted more than 405nm (as this is the range increase at max payload), so the advantage for the MAX is even larger than 3645nm vs. 3510nm.
I have just (and admittedly not just one time) offered my doubts about the LEAP-X concept, especially for the B737, where the fan diameter is restricted. You just can't argue against physics. And I have seen and read that I am not the only one who have doubts - also regarding the LEAP-1A for the A320neo. And in my last blog I just quoted what was stated in the article with some own comments. I will quote now the preamble of this article to underline that these statements are not my statements, but that they seem to be well researched and credible:

Before you read this article
In the course of its research Airline Economics has gained direct input from the signatories on both sides of agreements for the aircraft and engines in question, from airlines, original equipment manufacturers and lessors. We also have had input from people involved in deals and engineering input from those working on the programmes. Airline Economics is now aware how much was paid for what, what mistakes were made, and knows who is worried. See Airline Economics, issues one, two and three, 201, for background on these aircraft and their engines. Thank you to those that helped with this article.

Currently I am working on a comparison between the A350 family and the proposed B777-X. I am not done yet, but I can already say that the A350, especially the -1000 will not look too good. The -800 will be (if ever build, what seems to be doubtful) what Michael O'Leary would call a dogs dinner, but falls out of the comparison with the B777-X family anyway and does not look good against the B787 family.
Finally, I am a big fan of the GE90-115B fan - not to forget the rest of the engine!
