The complex situations during a fire disaster, such as high temperature, toxic gas and thick smoke, require helitack crew possess good professional skills.

According to the requirements of helicopter special operation, a prototype is proposed in this paper, and a virtual training system based on some kind of helicopter was developed to validate the prototype’s function, framework design and its capability for further development.
