This issue has been further developed in the Flight Safety Analyst Handbook:. Section 1 presents the historical basis for EWRexplains the organization of the chapters in the Range Safety Requirements, and describes the organization and management of the 45th and 30th Space Wings with a focus on the Offices of Safety and those groups impacting the safety approval process.

Ewrr responsibilities, such as generating safety requirements, operational testing and evaluation, and all prelaunch and launch safety operational functions, would be retained by AFSPC. The AFMC safety office would also be responsible for certifying safety readiness for other government, civil, and commercial launch operations at the WR and ER, as outlined below. Numbers indicate time after launch in seconds.

These inconsistencies are examined in light of the risk posed by vehicles as they approach orbit to show that downrange safety-related assets can be eliminated while safety is maintained within accepted limits. See Primary Recommendation on Roles and Responsibilities, below. In a space operations command i. Participants in Committee Meetings 49—50 Appendix D: The ILLs are not explicitly defined by safety metrics such as E c.



Streamlining Space Launch Range Safety discusses whether range safety processes can be made more efficient and less costly without compromising public safety. At the WR, safety analyses are rerun on launch days using measured wind data to reevaluate the safety metrics and verify that the launch meets the accepted safety criteria.

The number of individual requirements in EWRwhich add to the costs borne by both the Air Force and the launch customer, would be greatly reduced. The basic responsibility of the range safety offices—the protection of human life and property—should not be changed. The IIP encounters the Africa gate seconds after launch. If the IIP fails fwr move downrange at the proper rate as shown on the chevron display, destruct commands are sent. It will be important to establish a concept of operations that ensures ewf decisions are objective and provides for effective communications between acquisition and operational commands involved in range safety.

P c can be used to determine whether specific personnel are at high risk in a given area. At the ER, the measured winds are compared against predefined worst-case winds to determine if the launch may proceed. Our interpretation is that DoD Directive In fact, the additional complexity may have no effect—or even a negative effect— on accuracy.

The goal should be to obtain the most accurate answer, not the most conservative one.

This issue has been identified and discussed by the RCC:. The committee endorses this and other efforts to determine the validity of ewf requirements in light of industry standards and existing laws and regulations. For example, the ranges use different assumptions and models in computing safety metrics, such as E cand they use analytical results differently.

As indicated above and in Appendix Ethe committee noted that conservatism is, in fact, built into many range safety analytical models and procedures.

ew The gates are perpendicular to the nominal trajectory, and the width of the gates accounts for tracking uncertainties and acceptable variations in trajectory. Switch between the Original Pageswhere you can read the report as it appeared in print, and Text Pages for the web version, where you can highlight and search the text.

In parallel with this study, SMC, which is part of AFMC, initiated a study to document the sources of requirements, determine which requirements are design solutions, and identify the actual standards represented by design solutions. Risk standards then can be used to derive safety requirements, and old requirements not needed to satisfy risk standards can be eliminated.
