PurposeThe development of the procedural simulator for the

UAV’s operators training (Flight Plan Programming)

TasksTo analyse the general principles of the unmanned

aircraft systems;To process information about the existing methods of

operators training and methods of flight simulation;To choose an appropriate mathematical model for the

flight programming;To develop a navigational model and the algorithm of

the simulator;To implement the developed models and algorithms

to create procedural simulator 2

Conclusions

As a result of the work the model of the procedural simulator for the UAV’s operators training was created. Simulation method used for programming was previously presented at scientific conferences. For further improvement and promotions of practical usage of the developed trainer model the list of recommendations is created.

Recommendations

The simulator may be used in the educational process to study the basic principles of the UAV flight

Developed model of the UAV simulator can be used for future flight simulation projects

Approbation of the results1. Proposed UAV simulation method firstly was

represented at the All-Ukrainian competition of student research papers "Aviation and rocket-space equipment. Air Navigation" (02.04.2015).

2. Also there was the participation in XII International Scientific Conference "AVIA 2015" (28.04.2015)
