# Description

The purpose of this e-book - to make the process of calculating their own aircraft more affordable for a wide range of amateur designers. Despite the fact that there is a sufficient number of books on aviation planning for schools and benefits for designers, they are sinning unnecessary complexity in the presentation of the material, considering all aspects of the design of aircraft, including for example, and supersonic. New Designer is virtually 100% of the aircraft designs for independent operations and training. For such aircraft developed certain criteria to get a simple to operate and safe to use the unit. It was they who formed the basis of this guide. Everything else should be added that the proposed guide you to illustrate the calculation process uses a single example, that allows us to follow the entire process from beginning to end.

So, by setting in Step 1 of 4 parameters - number of seats, the stall speed, the power of the motor used and the operational handling, you will determine the future:
