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.
Investigators determined that the two pilots were exploring the performance limits of the empty CRJ-200 on the flight. The pilots decided to test the limits of the CRJ and join the "410 club," referring to pilots who pushed CRJs to their maximal approved altitude of flight level 410 (FL410) or 41,000 feet (12,497 m) above sea level.
This narrow window is called the "coffin corner", [42] [43] because breaching either limit was likely to cause airflow separation at the wings or tail. [44] For most of the time on a typical mission the U-2 was flying less than five knots (6 mph; 9 km/h) above stall speed.
Transonic flow patterns on an airfoil showing the formation of shock waves at different Mach numbers (M) in high-speed flight.. In high-speed flight, the assumptions of incompressibility of the air used in low-speed aerodynamics no longer apply.
Altitude envelope (H-M diagram).Contour is load factor. Turn rate envelope, described in an E-M diagram (doghouse plot). Contour is specific excess power. A doghouse plot generally shows the relation between speed at level flight and altitude, although other variables are also possible.
