Sample text
A new airplane must have all the features desired by the public and you have to know and anticipate what those features are. As an example, in history, the Boeing 247 had many of the technical advances of the DC-3. It was built only a year or two ahead of the DC-3. Most of you have never heard of a Boeing 247 because it was too small and after Boeing built something like 65 of them it disappeared from production. It was a fine looking airplane and it still is today. But it was a ten passenger airplane.
The number of factors involved in a market are very great. First, there is the basic travel growth pattern which will be discussed in more detail later. The there's the capacity of the projected-airplane. If you build the wrong size, just after you have spent several hundred million dollars in development, somebody else will come and build the right size and you'll have to take your airplanes and sell them off as unique lunchrooms. History has a few of those. There was large engine airplane built in the twenties called the Fokker F-32.
The next important characteristic is range. In order to get the market, the airplane has to be designed to cover the distances required by the passengers and the airplanes at that time. If the market is growing a great deal internationally, a new airplane tailored to the transcontinental routes with poor ability to do the international job, will face a severely reduced market. g. the DC-9 and the 737. Companies look for niches that can be filled in the spectrum of airplane range and payload. Then there is the total operating cost.
