AFMC is also responsible for the provision of sustaining engineering and depot-level maintenance for launch vehicles, upper stages, range systems, and associated ground equipment. A strict risk avoidance stance—reducing risk to the lowest possible level regardless of cost—would preclude space launch by making it unaffordable.

Downrange radar assets at Antigua and Ascension Islands are required to provide the vehicle position data used to compute the IIP beyond approximately seconds Figure In the course of its study of the risk criteria used at the WR and ER, the committee reviewed a number of documents. The Western Range implements this policy by constraining the azimuth of orbital launches. Rather than requiring that each user develop its own methods of compliance, the ranges defined many design solutions and included them in EWR as requirements.


Detailed, often step-by-step procedures and processes are dictated in annexes. Page 23 Share Cite.

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. In addition, examples of completed esr and an example of a portion of a Tailored EWR are included. Information on the FAA licensing process, including relevant statutes, regulations, and policies, is available on line http: Continued evolution and assessment of these modeling and analysis techniques is critical, especially for new types of launch vehicles such as RLVs.

The National Academies Press. Primary Recommendation on Risk Management.

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 12-71, you can accomplish this goal in a manner that is consistent with mission objectives with little 1271 no impact to your program budget or schedule.

Supplement to RCC Standard This would not be true if a malfunction occurred downrange that unexpectedly reduced vehicle thrust or directed a vehicle off the intended trajectory while maintaining stable, powered flight. From throughU.

In addition, the safety office could also develop, procure, and certify standard flight safety systems and make them available to users. The government itself is emulating commercial customers, shifting from direct management of launch programs to the purchase of space launch services from U. Safety procedures based on risk avoidance should be replaced with procedures consistent with the risk management philosophy specified by EWR Navy and Air Force, and aircraft flight tests.

The committee recognizes that determining which functions are involved in the development phase and where to draw the line organizationally between operations and development will be difficult because these functions have been closely linked for many years.

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. 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 of the engineers working with range safety personnel.

Because of inherent uncertainties in input parameters and modeling assumptions, safety assessments can provide only approximate results, even though range safety personnel are constantly improving their analytical models based on actual range experience. These functions include developmental testing and evaluation, sustaining engineering, and certifying that system designs meet safety requirements. The current placement of Africa gates derived from ILLs and destruct lines is based on risk avoidance.

Air Force Memorandum of Agreement on Spacelift. For credibility and liability protection, it is better to change the criteria before initiating a launch operation, than to establish erw and then violate it 30th SW, The vehicle must pass through the gate or the flight will be terminated. Both MOAs confirm the intent that AFMC assume responsibility for the acquisition, developmental testing, sustainment, and improvement of launch vehicles, spacecraft, and 127-11 range systems.

With space launches, this risk applies to the loss of the mission, property damage, or casualties for mission personnel or the public at large.


Requirements should be retained in EWR This information would also be necessary for the settlement of international claims or disputes in the event that a malfunction occurs beyond the destruct capabilities of the ranges 45th SW, The IIP encounters the Africa gate seconds after launch. Page 18 Share Cite. Areas of particular interest include onboard safety systems, such as FTSs, receivers, batteries, and tracking devices.

The ranges also use an individual risk criteria, P cto describe the probability of an individual in any particular place being killed or severely injured during a launch. In addition to the operational workforce, each AFSPC range safety office also has an engineering workforce that establishes flight safety system ewg and testing requirements and certifies that flight safety systems meet safety requirements at the component, subsystem, and system levels.

Instead, they are based on risk avoidance: The tailoring process has. Because the launch 217-1 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. Vandenberg Air Force Base, Calif.: 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 This chapter describes a risk management approach to space launch range safety.

For failure modes in which thrust ends prematurely, a thrust-termination type of FTS would have no added benefit. Remove all design solutions from EWR Eliminate requirements that cannot be validated. 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.

Transfer of Acquisition Functions to an Acquisition Command. The basic prelaunch safety assessment methodology used at both the WR and ER is based on Monte Carlo simulation tools, which is consistent with methods used in other fields.
