This intersection is the coffin corner, or more formally the Q corner. [3] The above explanation is based on level, constant speed, flight with a given gross weight and load factor of 1.0 G. The specific altitudes and speeds of the coffin corner will differ depending on weight, and the load factor increases caused by banking and pitching maneuvers.
The pilots' unprofessional behavior, deviation from standard operating procedures, and poor airmanship. The pilots' failure to prepare for an emergency landing in a timely manner, including communicating with air traffic controllers immediately after the emergency about the loss of both engines and the availability of landing sites.
The plane was approaching the coffin corner of its flight envelope, when the turbulence was encountered. After that near disaster, the stall mach buffet margins were widened on all jet aircraft, to preclude a plane getting into that situation again, where severe turbulence narrows the "coffin corner" margins so severely that the pilots do not ...
American Airlines pilots were told to make an “expedited climb” to avoid crashing into Hawaiian mountains Wednesday, according to the Federal Aviation Administration (FAA). An air traffic ...
That is the precise coffin corner that a pilot will be forced into: Hold the nose up, to prevent the plane from losing altitude----which would guarantee a stall and loss of control----or lower the nose to maintain control until it slams into the ground.
Pilots had to adjust to the U-2's unusual combination of jet engines and enormous, high-lift glider wings; because of the "coffin corner" they learned of the need to pay complete attention to flying when not using the autopilot. [61]
Two pilots died when their vintage planes collided in front of tens of thousands of spectators Sunday at the National Championship Air Races in northern Nevada, cutting the final day of the event ...
The H/V curve also contains a take-off profile, indicating how a pilot can start from 0 height and 0 speed, and safely traverse to cruise. At low heights with low airspeed, such as a hover taxi, the pilot can simply cushion the landing with collective by converting rotational inertia into lift. Conversely, a complete power loss, and resultant ...
