Course Description

This basic maintenance course offers a foundational understanding of helicopter operations through two integral modules. In Module 1, helicopter mechanics delve into aerodynamics, acquainting themselves with essential terminology and exploring the peculiarities of air flow around rotating wings. The module also addresses the influence of gyroscopic forces, encompassing the theory of flight and its application to different flight phases, including drift, the coriolis effect, autorotation, and ground effect. The training is reinforced with a multiple-choice questionnaire.


In Module 2, the focus shifts to helicopter construction and systems, covering fuselage construction methods, main and tail rotor components, fuel storage, hydraulic systems for flight control load reduction, and rotor blade tracking. The course concludes with a comprehensive multiple-choice questionnaire, ensuring participants acquire a holistic understanding of basic helicopter principles and operations.
