Pearson International Airport, Ontario, to Montréal/Pierre Elliott Trudeau International Airport, Quebec. At 1457 Eastern Daylight Time, the aircraft touched down in heavy rain showers about 2550 feet beyond the threshold of Runway 24L and did not stop before reaching the end of the runway. The aircraft departed the paved surface at a ground speed of approximately 39 knots and came to rest on the grass, approximately 200 feet past the end of the runway.

Aircraft Accident Report NTSB/AAR-16/02. Washington, DC. Abstract: This report discusses the March 5, 2015, accident in which Delta Air Lines flight 1086, a Boeing MD-88 airplane, N909DL, was landing on runway 13 at LaGuardia Airport, New York, New York, when it departed the left side of the runway, contacted the airport perimeter fence, and came to rest with the airplane’s nose on an embankment next to Flushing Bay. The 2 pilots, 3 flight attendants, and 98 of the 127 passengers were not injured; the other 29 passengers received minor injuries. The airplane was substantially damaged. Safety issues discussed in the report relate to the use of excessive engine reverse thrust and rudder blanking on MD-80 series airplanes, the subjective nature of braking action reports, the lack of procedures for crew communications during an emergency or a non-normal event without operative communication systems, inaccurate passenger counts provided to emergency responders following an accident, and unclear policies regarding runway friction measurements and runway condition reporting.

  • 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.

For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C.. 20402 - Price $1.00 Foreword OR CENTURIES MAN HAS DREAMED of exploring .the universe. FFinally an expanding rocket technology brought with it a rea­ sonable expectation of achieving this dream, and man was quick to accept the challenge. Project Mercury was an organized expres­ sion of man's willingness to face the risks invol ved in exploring the new frontier of space, and of his confidence in our Nation's ability to support him technically and professionally in this ex­ citing adventure. Project Mercury is now legend. The story of its many activi­ ties is an important chapter in the history of our times. Its spot­ less record of successes is a tribute to all those who made up the Mercury team. Not the least of the groups composing the Mercury team was that charged with responsibility for the health of the astronauts. This select biomedical group discharged ,dtll near perfection a variety of tasks involved in choosing and training our Nation's first space voyagers, monitoring their medical status during each flight, and finally assessing their condition after the flight. In this volume the author sets forth a chronological account of a unique medical support program.

  • INTRODUCTION the Global Landing Gear System Is a Retractable Tricycle Type Consisting of Two Main Landing Gear Assemblies and a Steerable Nose Landing Gear Assembly
    Bombardier Global Express - Landing Gear & Brakes INTRODUCTION The Global landing gear system is a retractable tricycle type consisting of two main landing gear assemblies and a steerable nose landing gear assembly. Each assembly is equipped with a conventional oleopneumatic shock strut. On the ground, all three landing gear assemblies are secured with gear locking pins. The landing gear is fully enclosed when the gear is retracted. Normal extension and retraction is electrically controlled by the Landing Gear Electronic Control Unit (LGECU) and hydraulically operated by systems 2 and 3. Emergency extension of the landing gear system is enabled through the Landing Gear Manual Release System handle in the flight compartment. Each landing gear assembly has twin wheels and tires. The main wheels have hydraulically powered and electrically actuated carbon brakes, controlled through a brake-by-wire system. Main landing gear overheat detection is available. Antiskid protection and automatic braking is provided. The main and nose landing gear assemblies use proximity sensors to provide air and ground sensing. This is accomplished by two sensors (referred to as weight-on-wheels or WOW) on each assembly. All hydraulically actuated doors, uplocks, downlocks and nose shock strut (centering) use sensors to determine their position for gear operation. Landing gear status and position is visually displayed on EICAS and aurally annunciated in the flight compartment. The antiskid, nosewheel steering indication and status are also displayed on EICAS and
