Fire Buddy is a training aid for engine and truck companies. For the engine, it allows the calculation of friction loss and engine pressure for a given hoseline. The user can pre-define multiple hose loads where commonly used or preconnected lines can be saved and recalled. Friction loss can be calculated for hose diameters from 3/4" to 6" with appliances. Elevation changes, friction loss and required nozzle pressure are all used to calculate the necessary engine pressure.

For the truck, it allows the user to make calculations related to the reach of an aerial ladder. The user specifies two of the following three parameters: Ladder extension, distance away from the building and vertical height of the building. The app will then calculate the third parameter as well as the angle of the ladder that will be required.
