With the development of a flight preparation assisting system as an example,this paper gives a detailed account of the techniques and method of using electronic chart in general aviation flight preparation,including geographical information,navigational data and how to set up a performance databank for different types of aircraft as well as air route preparation and how to make flight plans,etc.

Aiming at the shortcomings of the conventional flight plan management and based on the algorithm of MK-NN track association, a method is presented to associate integrated track and plan track.

Aimed at the drawback of the conventional flight plan management, a flight plan management system is devised in this paper.

It is aimed at assisting the flight planning process, controlling precisely the planned air traffic flow at stations and areas, presenting advisory suggestions for illegal flights, and to assisting the planner to search for acceptable new time schedule.

A typical algorithm about flight planning is present at length, the database complexity and other difficulties of this algorithm are discussed.

Design and Implementation of the Comprehensive Plan Information Management System;

CPMS can provide a unified information platform and efficient working platform for comprehensive plan management.

The application of CAD in working out enterprise comprehensive plan is introduced.

This paper puts a concept forward to Resoures-lack Production systerm,and estabishs mathmatical modules of(3-arrangement) from Overall Planning to Detail Schaduling for it,i.
