The regulator makes it possible to start different types of airplanes with a single starter, providing it the pressure and air flow required. Upon the operator selecting the start step corresponding to the plane to start, the convenient rating of the turbine is set by operating a simple control that controls the flow of fuel to the combustion chamber, using the indications of a sensor that indicates to it the rotation speed achieved by the turbine. When the operation so requires, in order to obtain the pressure and air flow that the airplane needs to start, the system also activates different mechanisms. As an alternative, by means of a microprocessor the start step corresponding to the plane to start can be chosen automatically, using the indications of pressure and flow at the inlet of the airplane.

Electricity generating tractor for various airport services, constituted by an electric-drive car on whose platform a driver's cabin is positioned in its front side, which driver's cabin is provided with control and check instruments, and in its rear side a generator is installed, which consists of a Diesel engine driving a three-phase alternator equipped with a suitable rectifier in order to supply the direct current necessary for causing said car to move, for checking the on-board aircraft instruments from ground level, and for starting up the turbine engines of the aircrafts. Alongside said generator groups of electrical batteries are installed, which are automatically connected with said generator in order to act as back-up batteries; said back-up batteries are suitable for directly powering the car drive motors, and for supplying the necessary electrical energy for starting up the turbine engines of the aircrafts, and for carrying out the on-board checks in all cases of stopping of said generator.
