Abstract
Described is a heads-up display system for an aircraft having a rotating propeller assembly. The heads-up display system includes an electrical interconnection sheet and a plurality of light-emitting diodes (LEDs) electrically connected to the electrical interconnection sheet. The heads-up display also includes means for securing the electrical interconnection sheet onto an outer surface of a propeller blade. A graphics generator disposed in the rotating propeller assembly is in electrical communication with the electrical interconnection sheet to control illumination of the LEDs while the propeller assembly rotates.
