Okay LH423, about the second engine choice for the 318 now. You learn something new every day.
I personally think that is a mistake by Airbus because it will drive up costs.
Now as to the flame from Pratt-Whitney... What's up with that? I am human, I make mistakes. My bad. But, you cry about another poster criticizing you (really not as harsh as you took it to be considering no one used the word 'insane') and then you flame me for an honest mistake?
Anyways, I do clearly remember reading in AW&ST that P&W were considering a geared turbofan for the 318 project.
USAirways737: As for the 717-200 not a good choice for medium range, that's not really what I was getting at. It only has a range of nearly 1600 miles. (Obviously not enough for US transcon.) The 318 range is a whopping 3200 miles. That range comes at a price, and that is structural weight; it weighs much much more than the 717. I believe though it is also much faster than the 717. The end results of all these facts is that the 717 being slower, but incredibly efficient, and short ranged makes it an EXCELLENT short hopper jet, with quick turnarounds, and serviceability at locations that don't offer ammenities such as large ground staff or long runways. Its slow speed isn't much of a consideration since the trips will be spent mostly taking off and in landing patterns where all planes go about the same speed anyways. The 318, being bigger (in weight) affords it double the range of the 717, and allows transcontinental service from markets that are too small to justify any other bird. Think about it!
Providence to Fresno, or Tallahassee-Wallawalla.
Well, maybe not that small, but the 318 would allow nonstops that currently aren't feasible.
Just don't make the mistake that if two planes are the same capacity that they serve the same role. The 717 and the 318 are not in the same market, and do not serve the same purpose. I get a little upset when I hear things like "I prefer the 318 over the 717." (Let aside that not a single one of us has ever seen or riden a 318...) Well, I prefer the 777 over the J41. Doesn't really say much though, does it?
