  • Limitations of Spacecraft Redundancy: a Case Study Analysis
    44th International Conference on Environmental Systems Paper Number 13-17 July 2014, Tucson, Arizona Limitations of Spacecraft Redundancy: A Case Study Analysis Robert P. Ocampo1 University of Colorado Boulder, Boulder, CO, 80309 Redundancy can increase spacecraft safety by providing the crew or ground with multiple means of achieving a given function. However, redundancy can also decrease spacecraft safety by 1) adding additional failure modes to the system, 2) increasing design “opaqueness”, 3) encouraging operational risk, and 4) masking or “normalizing” design flaws. Two Loss of Crew (LOC) events—Soyuz 11 and Challenger STS 51-L—are presented as examples of these limitations. Together, these case studies suggest that redundancy is not necessarily a fail-safe means of improving spacecraft safety. I. Introduction A redundant system is one that can achieve its intended function through multiple independent pathways or Aelements 1,2. In crewed spacecraft, redundancy is typically applied to systems that are critical for safety and/or mission success3,4. Since no piece of hardware can be made perfectly reliable, redundancy—in theory—allows for the benign (e.g. non-catastrophic) failure of critical elements. Redundant elements can be 1) similar or dissimilar to each other, 2) activated automatically (“hot spare”) or manually (“cold spare”), and 3) located together or separated geographically5-7. U.S. spacecraft have employed redundancy on virtually all levels of spacecraft design, from component to subsystem7,8. Redundancy has a successful history of precluding critical and catastrophic failures during human spaceflight. A review of NASA mission reports, from Mercury to Space Shuttle, indicates that redundancy has saved the crew or extended the mission over 160 times, or roughly once per flight9.

  • Ac 61-107B Chg 1
    U.S. Department Advisory of Transportation Federal Aviation Administration Circular Subject: Aircraft Operations at Altitudes Date: 9/9/15 AC No: 61-107B Above 25,000 Feet Mean Sea Level Initiated by: AFS-800 Change: 1 or Mach Numbers Greater Than .75 1. PURPOSE. This advisory circular (AC) alerts pilots transitioning from aircraft with less performance capability to complex, high-performance aircraft that are capable of operating at high altitudes and high airspeeds. In particular, this AC stresses special physiological, equipment, and aerodynamic considerations involved in these kinds of operations. It also provides information to aid pilots in becoming familiar with the basic phenomena associated with high-altitude and high-speed flight. 2. PRINCIPAL CHANGES. Individual variability in hypoxia tolerance was the basis of discussions between the National Transportation Safety Board (NTSB) Chief Medical Officer and the Federal Aviation Administration (FAA) about whether to continue to include information in this AC relating to time of useful consciousness (TUC) (a measure of hypoxia tolerance) with increasing operational altitudes. TUCs are based on data that represent average values and reflect wide variation among pilots in terms of time to incapacitation. There was concern that this table was misleading because of the considerable ranges in TUCs given. Rather than delete the table from the AC, we agreed to augment it with more specific information on why hypoxia tolerances vary among individuals. This is in the form of a CAUTION statement presented underneath the original table. This change also incorporates editorial corrections throughout the document.

Upon detailed inspection of the same aircraft, no damage to the aircraft was observed; however, it was found that both valves for the intake of bleed air from the left and right engines into the respective air conditioning packs had temporarily malfunctioned and were closed.
