Meztilabar It may also be feasible to move other gates uprange and further reduce the need for downrange facilities. Login or Register to save! Operational responsibilities, such as eer safety requirements, operational testing and evaluation, and all prelaunch and launch safety operational functions, would be retained by AFSPC. Converge the modeling and analysis approaches, tools, assumptions, and operational procedures used at the Western and Eastern Ranges. Range safety user manual EWR Eastern and Western Range To manage the safety aspects of the acquisition-like functions specified in the memorandum of agreement, AFMC should establish an independent safety office. If downrange tracking is needed for reasons other than risk management, those requirements should be documented.

Brakus A clear distinction would be made between non-negotiable performance-based requirements and approved methods of compliance that can be waived if an equally effective alternative is available. First, most major vehicle events staging and engine starts occur within approximately seconds of launch while the vehicle is well within the area covered by uprange assets.

No launch site worker or member of the general public has been killed or seriously injured in any of the 4, launches conducted at the ER and WR during the entire year ewg of the space age. Nuclear and chemical industry Netherlands. Vandenberg Air Force Base, Calif. The National Academies Press. However, conservatism may also overly restrict operations and should be carefully limited.

In addition, print and electronic accessibility to a variety of Range Safety documents is discussed. The use of gates and their locations are defined by EWR and related Air Force documents—the committee knows of no international agreements that require their use. Destruct lines and flight termination system requirements should be defined and implemented in a way that is directly traceable to accepted risk standards. 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.

Tailoring provides range users great flexibility, but it also reveals a serious shortcoming in the usability of EWR EWR includes a great deal of detailed information on organizational roles and responsibilities.

Er 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. 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.

Detailed, often step-by-step procedures and processes are dictated in annexes. 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. Eliminate requirements that cannot be validated. With space launches, this risk applies to the loss of the mission, property damage, or casualties for mission personnel or the public at large.

Finally, general safety assessment and modeling issues are presented, followed by an outline of the major differences in modeling swr analysis methods at WR and ER.

When combined with the subsequent probabilities of impacting a populated area and causing casualties, 5 the risks from flying over Africa appear to be well within the standard acceptable for the U. Even if a failure were to occur more than seconds after launch, the vehicle is travelling very fast and it would break up from dynamic forces upon reentering the atmosphere.

Also, close working relationships between operational staff at the ranges and acquisition staff within AFMC must be maintained to ensure that new systems and system modifications are consistent with operational needs and can be ewwr implemented in an operational setting. At the ER, the measured winds are compared against predefined worst-case winds to determine if the launch may proceed.

The location of the Africa gate typically corresponds to the position of the IIP at approximately to seconds after launch see Figure Page 22 Share Cite. 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.

The Western Range implements this policy by constraining the azimuth of orbital launches. Several factors suggest that the collective risk standard, E ccould still be met if the Africa gates were moved uprange.

Page 17 Share Cite. The tailoring process has. The vehicle must pass through the gate or the flight will be terminated. These include differences in analysis software packages, methods of defining ship exclusion zones, and displays for monitoring the launch vehicle trajectory.

System program directors are responsible for all aspects of new system. Over the years, research and development related to ICBMs, SLBMs, and other space launch systems have been reduced, and operations have became increasingly important. P c can be used to whether specific personnel are at high risk in a given area. Thus, in terms of range safety there is no clear justification for retaining downrange assets at Antigua and Ascension.

Hazardous material storage Hong Kong. These thresholds are ultimately based on impact limit lines ILLswhich extend downrange from the launch site and define the area in which debris from planned stage drops, vehicle explosions, swr thrust termination may land. AFSPC should simplify EWR so that all requirements are performance based and consistent with both established risk standards for space launch e. Such changes could render invalid the informed decision process which helps protect the government from liability RCC, a.

These acquisition-like functions overlap the responsibilities of AFMC. The goal should be to obtain the most accurate answer, not most conservative one.

Flight trajectories and ILLs are calculated and approved prior to launch to protect people and property. Despite the inherent danger of space launches, the U.

Obtaining final Range Safety approval to launch can be a tedious and difficult objective to achieve; however, with an understanding of the process, proper planning, and proper engineering, you can accomplish this goal in a manner that is consistent with mission objectives with little or no impact to your program budget or schedule. The Range Safety office will support you in your effort to achieve a successful and safe mission. Although this Handbook is not regulatory except when repeating or referencing EWR , it does contain guidance that will make the Range Safety approval to launch process simpler and more expedient. The Handbook is divided into four separate sections.
