Abstract

An unmanned aerial vehicle intelligent emergency voice report system and method includes monitoring operational parameters of the UAV, monitoring environmental parameters within and external to the UAV, and processing the operational parameters and the environmental parameters, in a controller, to determine when the UAV is in an emergency condition. When the controller determines the UAV is in an emergency condition, the controller is used to: process the operational parameters to determine how the UAV will respond the emergency condition; automatically determine a communication transmission frequency; tune an onboard communication device to the communication transmission frequency; generate analog voice waveforms that provide information regarding the emergency condition; supply the analog voice waveforms to the onboard communication device; and command the onboard communication device to transmit the analog voice waveforms on the communication transmission frequency.
