Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...
ValuJet Airlines Flight 592 was a regularly scheduled flight from Miami to Atlanta in the United States. On May 11, 1996, the ValuJet Airlines McDonnell Douglas DC-9 operating the route crashed into the Florida Everglades about ten minutes after departing Miami as a result of a fire in the cargo compartment caused by mislabeled and improperly stored hazardous cargo (oxygen generators).
The International Board for Research into Aircraft Crash Events (IBRACE) was founded on 21 November 2016 by a group of subject-matter experts in aviation (cabin safety and accident/incident investigation), engineering (sled-impact testing, aerospace materials, lightweight advanced-composite structures, and air transport safety and investigation), clinical medicine (specifically, orthopaedic ...
Per the Convention on International Civil Aviation, if an aircraft of a contracting State has an accident or incident in another contracting State, the State where the accident occurs will institute an inquiry. The Convention defines the rights and responsibilities of the states.
the shear force due to the viscosity of the gas, also known as skin friction. Pressure acts normal to the surface, and shear force acts parallel to the surface. Both forces act locally. The net aerodynamic force on the body is equal to the pressure and shear forces integrated over the body's total exposed area. [4]
Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
Final communication with the aircraft occurred at 23:07. At 23:09, as the aircraft was on course to the Trinidad Intersection, the left wing and number one (left outboard) engine separated from the aircraft. Pieces of the wing, blown back by the wind–blast, struck and dislodged the horizontal stabilizer. The right wing's planking then broke ...
In the late 1960s, the Army published the Aircraft Crash Survival Design Guide. [4] The guide was changed several times and turned into a set of books with different volumes for different aircraft systems. The goal of this guide is to show engineers what they need to think about when making military planes that can survive a crash.
