The question is ambiguous, but the answer is probably supposed to be "decreasing".

The explanation provided is sort of misleading if taken to the word. The flat-rated portion of the takeoff...

I don't think it is a wheel loading issue - which can be easily controlled in design - as much as it is the MTOGW of the airplane when it comes to runway and taxiway bridges.

I think it makes sense for the carriers introducing the A380 to foot a significant portion of the costs to accommodate it - especially since we are talking about foreign carriers for the most part. ...

Yes - understood.
My point is that the 80E1 is a fairly mild derivative of the 80C2, and was probably certified based on a "same core" philosophy - i.e. the high compressor, burner and high turbine...

320Driver - I find your praise of Airbus and GE quite interesting in what might otherwise be cause for concern in the community. Since this problem is apparently (per the recent operator letter and...

LGB -





In your timing proposition for takeoff, it seems it would be a human factors challenge to add another task to the takeoff workload. But it is an interesting concept. I wonder how...

I have read that the Venezuelans (accident site) and Colombians (carrier home) are the primary investigators on this accident. It appears that the BEA's task was to assist the investigators in...

The 777 had a wingspan length constraints of 200 ft. maximum (it ended up at 199'11"), which was probably based on airline input (presumably to fit 747 Classic gates). Some airlines also wanted...

Never trust GE for a real-world EPR definition.

The more standard definition (ala P&W) for a dual-spool turbofan uses the LP turbine EXIT total pressure, not the inlet.

I think the first...

Southwest, American, United (mid-90's to mid 00's), KLM, Northwest, DHL are just a few non-whites that immediately come to mind. Thousands of airplanes in that group.
