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 127-1 (Eastern and Western Range 127-1)
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. The effect of this conservatism is that actual operations are likely to be safer than predicted.
Probability of Failure per second. While other requirements may exist, from the perspective of launch range safety the Air Force should move the Africa gates to within the limits of uprange flight termination and tracking systems; eliminate the use of assets in Antigua and Ascension for range safety support; and conduct a detailed technical assessment to validate the feasibility of moving other gates uprange.
Despite the inherent danger of space launches, the U. If the Commander exceeds the criteria it can be argued that the criteria does not exist, or was in fact, never a valid criteria. The Handbook is divided into four separate sections.
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. Maintaining, staffing, and operating downrange facilities and providing reliable, ewt communications between the downrange facilities and the Range Operations Control Center ROCC at the ER is expensive.

Obtaining final Range Safety approval to launch ewrr 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.
Following these events, vehicles have historically been quite reliable. 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.
Moving the Africa gates to within the reach of uprange flight termination, telemetry, and tracking systems is not likely to increase E c significantly or. Both ranges compute how long 12-71 would take for a vehicle to present an unacceptable risk if it flew straight up. Not a MyNAP 127-11 yet?

In fact, the additional complexity may have no effect—or even a negative effect— on accuracy. If the IIP fails to move downrange at the proper rate as shown on the chevron display, destruct commands are sent.
See Chapter 5 for a discussion of limits on individual hit probabilities, P ifor ships and aircraft. Air Force Memorandum of Agreement on Spacelift. After seconds, for ear, the probability of an Atlas failure is estimated at The location of the Africa gate typically corresponds to the position of the IIP at approximately to seconds after launch see Figure Flight trajectories 1271- ILLs are calculated and approved prior to launch to protect people and property.
Requirements should be retained in EWR Although risk standards specified in EWR are consistent with a risk management approach to safety, many of the specific guidelines in EWR 1271- the standards in a way that avoids erw. The differences may increase costs because of overlap or duplication of effort in developing models, software, and hardware for the two ranges. Department of Defense Directive Orbital vehicles are tracked and FTS commands are issued only to the horizon i.
EWR is issued under the authority of the 30th and 45th wing commanders.
Safety procedures based on risk avoidance should be replaced with procedures consistent with the risk management philosophy specified by EWR Also, you can type in a page number and press Enter to go directly to that page in the book. At the ER, the measured winds are compared against predefined worst-case winds to determine if the launch may proceed.
Finally, general safety assessment and modeling issues are presented, followed by an outline of the major differences in modeling and analysis methods at WR and ER.

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. System program directors are responsible for all aspects of new system. Based on feedback from you, our users, we’ve made some improvements that make it easier than ever to read thousands of publications on our website.
Remove all design solutions from EWR It will be important to establish a concept of operations that ensures safety decisions are objective and provides for effective communications between acquisition and operational commands involved in range safety. Eliminate requirements that cannot be validated. Analyzing, testing, and certifying the design of new and modified systems involves staff assigned to many different elements of the range safety offices at the WR and ER.
Memo for esr Record. In addition, inconsistencies in the tailoring process may mean that different users incur different costs to certify the same equipment depending, in part, on the negotiating skills and expertise wer the engineers working with range safety personnel.
The complete transfer of range safety development, developmental testing and evaluation, and sustaining engineering to AFMC would, if properly implemented, increase efficiency and reduce costs without compromising safety by eliminating overlapping responsibilities between the ranges and 1227-1, by minimizing differences 1271- range safety policies and 127-11 applicable to the Western and Eastern Ranges, and by enabling users to deal with a single office when seeking approval ew use new or modified systems on both ranges.
