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.
A V-n diagram showing V S (stall speed at 1G), V C (corner/maneuver speed) and V D (dive speed) A chart of velocity versus load factor (or V-n diagram) is another way of showing limits of aircraft performance. It shows how much load factor can be safely achieved at different airspeeds. [3]
Coffin corner may refer to: Coffin corner (aerodynamics), an unstable combination of speed and altitude; A position in a bomber formation combat box;
Typical fields in the title block include the drawing title (usually the part name); drawing number (usually the part number); names and/or ID numbers relating to who designed and/or manufactures the part (which involves some complication because design and manufacturing entities for a given part number often change over the years due to ...

The diagram is not well explained by the article and is not a very obvious or traditional example. First, it is confusing for the article to describe the coffin corner as the convergence of stall speed and critical mach number, and then show a chart that goes well into the supersonic range (obviously from a fighter jet or similar).
The former CEO of Abercrombie & Fitch (A&F) has dementia and late onset Alzheimer's disease, his legal team has said in a court document filed in New York.
The camber and thickness of the aerofoil affect the critical Mach number, with a more highly curved upper surface causing a lower critical Mach number. On a swept wing the shock wave typically forms first at the wing root, especially if it is more cambered than the wing tip. As speed increases, the shock wave and associated lift extend outwards ...
