Nuclear and chemical industry Netherlands. The basic responsibility of the range safety offices—the protection of human life and property—should not be changed. This issue has been identified and discussed by the RCC:. In the course of its study of the risk criteria used at the WR and ER, the committee reviewed a number of documents. In addition to the operational workforce, each AFSPC range safety office also has an engineering workforce that establishes flight safety system design and testing requirements and certifies that flight safety systems meet safety requirements at the component, subsystem, and system levels.

Several factors suggest that the collective risk standard, E ccould still be met if the Africa gates were moved uprange. Next, certain inconsistencies between these accepted risk-management criteria and operational methods based on risk avoidance are described.
It may also be feasible to move other gates uprange and further reduce the need for downrange facilities. In support of the acquisition process, AFSPC is responsible for defining and prioritizing operational requirements for existing and new launch vehicles and systems and for communicating those requirements to AFMC. See Primary Recommendation on Roles and Responsibilities, below.
The need for tailoring, as it is currently practiced, could be greatly reduced or eliminated. Because the launch rate is quite low compared to the rate at which new technologies are developed, however, it can be difficult to predict the performance of new vehicles or systems using historical data. However, as already noted, the WR has demonstrated that the collective risk standard can be met without tracking, telemetry, or FTS during the later stages of flight.

EWR does not describe the source of most of its requirements. Neither DoD nor AFSPC instructions establish different risk standards for citizens of the United States and citizens of foreign nations, and the ER allows vehicles to proceed over Europe and Africa without further swr if the vehicles have successfully navigated the appropriate gates.
Users would have the option of 1 implementing the approved 1277-1 of compliance to streamline the review process, or 2 using an alternate means of compliance, for which users would accept the responsibility for getting approval. At the Eastern Range, the downrange location of gates and destruct lines and current requirements for downrange coverage by flight termination, telemetry, and tracking systems are not directly related to accepted risk standards e.
Continued evolution and assessment of these modeling and analysis techniques is critical, especially for new types of launch vehicles such as RLVs. Patrick Air Force Base, Fla.: Also, to reduce the need to refer to regulations and instructions issued by other government organizations, many of their requirements were quoted, expanded, or paraphrased and inserted into EWR DoD Department of Defense.

The ewrr process has. The differences may increase costs because of overlap or duplication of effort in developing models, software, and hardware for the two ranges.
The 45th Space Wing made the following statement in response to a query from the committee:. Register for a free account to start saving and receiving special member only perks. First, the current risk criteria used by the Air Force are discussed. Soon thereafter responsibilities for development and sustaining engineering of range instrumentation were transferred back to an acquisition command i. Hazardous material storage Hong Kong. In addition, print and electronic ewwr to 127-11 variety of Range Safety documents is discussed.
Moving the Africa gates uprange has the potential to 12-71 the cost of safety-related downrange assets, decrease the complexity of range safety operations, and reduce launch holds and delays. For example, the ranges use different assumptions and models in computing safety metrics, such as Ear cand they use analytical results differently.
Primary Recommendation on EWR Close coordination between operational staffs at the ranges, system operators or developers, and the AFMC safety office would be necessary to evaluate risks, generate new safety tools, establish appropriate risk standards, and manage risk for these missions.
At this stage of flight, fuel 127- often is used for flight termination instead of explosive 127–1. Page 20 Share Cite. At the ER, the measured winds are compared against predefined worst-case winds to determine if the launch may proceed. Although differences in geography and other factors may make it impractical for the ER and WR to use identical modeling and analysis approaches, an effort should be made to increase the degree of commonality in accordance with the Primary Recommendation on EWR The location of the Africa gate typically corresponds to the position of the IIP at approximately to seconds after launch see Figure Despite the inherent danger of space launches, the U.
Probability of Failure per second. Numbers indicate time after launch in seconds. Requirements for design, qualification, and acceptance testing processes would be removed from EWR and documented in an AFMC handbook describing acceptable means of compliance and lessons learned, in a manner consistent with the Primary Recommendation on EWR AFMC is responsible for development, qualification, and acceptance tests of new or modified systems to show that systems comply with all specifications and 1277-1 provided by the operational organization at the component, subsystem, and system levels.
The basic responsibility of the newly established AFMC safety office would be to support to the system program offices and AFSPC, as appropriate during the acquisition, developmental testing, sustainment, and improvement of space systems.

The last part of this chapter examines risk criteria, risk management, and analysis methods, including the potential for eliminating downrange safety-related assets at the ER.
Vandenberg Air Force Base, Calif.: Periodic, independent reviews should be conducted to ensure that the level of modeling ear is appropriate given the accuracy of model inputs and assumptions.
Our interpretation is that DoD Directive Based on the vehicle.
