Charles Radley

My career encompasses 19 years in aerospace system engineering with an emphasis on system safety and range safety. I have become a recognized expert in the NASA Payload Safety and the USAF Range Safety processes, via achieving NASA/DOD approvals for multiple spacecraft. So much so that I participated in an inter-agency committee to develop federal software safety standards, and was principal author of NASA-GB-1740.13-96 NASA Guidebook for Safety Critical Software. That Guidebook is now referenced by the FAA Advisory Circular 431.35-2.

A special aspect of my background is that I am truly interdisciplinary, with in-depth knowledge of the safety aspects of every subsystem and component part of an aerospace vehicle, including hardware and software, electrical, mechanical and all other subsystems.

Seasoned aerospace professional and space enthusiast. Highly motivated with an extensive breadth of
interdisciplinary technical and management skills. Specialized in all aspects of systems safety.
Follows a strong sense of ethics, and thereby gained the trust of government regulators (e.g. NASA,
DOD) and customers.
-Analyzes detailed complex issues while putting them in the “big picture” context
- Distills key points of complex issues for presentation to executives, regulators, subordinates
- Effective communicator. Team player and team leader
- Detail oriented while retaining a big picture perspective.
