Circular error probable ( CEP ), also circular error probability or circle of equal probability , is a measure of a weapon system's precision in the military science of ballistics . It is defined as the radius of a circle, centered on the aimpoint, that is expected to enclose the landing points of 50% of the rounds ; said otherwise, it is the median error radius. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, an average of 50 will fall within a circle with a radius of 100 m about that point.
67-400: The Boeing AGM-69 SRAM ( Short-Range Attack Missile ) was a nuclear air-to-surface missile . It had a range of up to 110 nautical miles (200 km; 130 mi), and was intended to allow US Air Force strategic bombers to penetrate Soviet airspace by neutralizing surface-to-air missile defenses. The SRAM was designed to replace the older AGM-28 Hound Dog standoff missile which

In February 2012, Boeing Global Corporate Citizenship partnered with the Insight Labs to develop a new model for foundations to more effectively lead the sectors they serve. The company is a member of the U.S. Global Leadership Coalition ,
201-462: A Washington D.C.–based coalition of more than 400 major companies and NGOs that advocate a larger International Affairs Budget, which funds American diplomatic and development efforts abroad. A series of U.S. diplomatic cables show how U.S. diplomats and senior politicians intervene on behalf of Boeing to help boost the company's sales. In 2007 and 2008, the company benefited from over US$ 10 billion of long-term loan guarantees, helping finance
268-421: A change of wind direction could have led to a conventional explosion and a widespread scattering of radioactive plutonium . The AGM-69A was retired in 1993 over growing concerns about the safety of its warhead and rocket motor. There were serious concerns about the solid rocket motor, when several motors suffered cracking of the propellant, thought to occur due to the hot/cold cycling year after year. Cracks in
335-672: A potential downgrade to junk status . On November 1, 2024, the IAM endorsed an improved contract offer which would see a 38% pay rise over four years, a $ 12,000 ratification bonus, and the reinstatement of an annual bonus scheme. On November 5, 2024, Boeing workers accepted the pay deal, ending a seven-week-long walk out. The company's three divisions are: Commercial Airplanes; Defense, Space & Security; and Global Services. In 2018 and 2019 , two Boeing 737 MAX narrow-body passenger airplanes crashed, leaving 346 people dead and no survivors. In response, aviation regulators and airlines around

Boeing has been accused of unethical practices (in violation of the Procurement Integrity Act ) while attempting to submit a revised bid to NASA for their lunar landing project. The firm has been criticized for supplying and profiting from wars , including
469-591: A role when measuring the accuracy of a position obtained by a navigation system, such as GPS or older systems such as LORAN and Loran-C . The original concept of CEP was based on a circular bivariate normal distribution (CBN) with CEP as a parameter of the CBN just as μ and σ are parameters of the normal distribution . Munitions with this distribution behavior tend to cluster around the mean impact point, with most reasonably close, progressively fewer and fewer further away, and very few at long distance. That is, if CEP
536-477: A safety inquiry. A decade earlier in September 1980, A B-52H on alert status at Grand Forks AFB in northeastern North Dakota experienced a wing fire that burned for three hours, fanned by evening winds of 26 mph (42 km/h). The wind direction was parallel to the fuselage, which likely had SRAMs in the main bay. Eight years later, weapons expert Roger Batzel testified to a closed U.S. Senate hearing that
603-470: A sort of standard deviation, since errors within this value make up 63% of the sample represented by the bivariate circular distribution. In turn, the properties of the Rayleigh distribution are that its percentile at level F ∈ [ 0 % , 100 % ] {\displaystyle F\in [0\%,100\%]} is given by the following formula: or, expressed in terms of

CEP is not a good measure of accuracy when this distribution behavior is not met. Munitions may also have larger standard deviation of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region . Munition samples may not be exactly on target, that is,

In 2020, Quartz reported that after the merger there was a "clash of corporate cultures, where Boeing's engineers and McDonnell Douglas's bean-counters went head-to-head", which the latter won, and that this may have contributed to the events leading up to the 737 MAX crash crisis. Boeing's corporate headquarters moved from Seattle to Chicago in 2001. In 2018,
1943-539: The aircraft. Upon rocket motor ignition, the missile tailcone was blown away by the exhaust plume. About 1,500 missiles were built at a cost of about $ 592,000 each by the time production ended in 1975. The Boeing Company sub-contracted with the Lockheed Propulsion Company for the propellants, which subsequently closed with the end of the SRAM program. An upgraded AGM-69B SRAM was proposed in

Five protesters in solidarity with the Palestinian cause were arrested on felony charges after blocking entrances to a Boeing facility in Heath, Ohio . The student union at Washington University in St. Louis passed a resolution calling on the university to divest from Boeing. The key trends of Boeing are (as at the financial year ending December 31): Between 2010 and 2018, Boeing increased its operating cash flow from $ 3 to $ 15.3 billion, sustaining its share price, by negotiating advance payments from customers and delaying payments to its suppliers. This strategy
3149-403: The mean vector will not be (0,0). This is referred to as bias . To incorporate accuracy into the CEP concept in these conditions, CEP can be defined as the square root of the mean square error (MSE).
