EADS Barfield was then bought in 2007 by the TAT Group subsidiary of Sabena technics, upon which the company returned to its original name. [2] [4] Since July 1, 2014, Barfield, Inc., has been acquired by the Air France Industries KLM Engineering & Maintenance Group (AFI KLM E&M). [5] The Franco-Dutch group has taken full control of Barfield.
It does this by giving an accurate measurement of the ambient atmospheric pressure (static pressure) well clear of the aircraft's fuselage. The trailing cone system trails at least one fuselage length behind the aircraft (SpaceAge Control) via a high-strength pressure tube. Static pressure is measured forward of the cone by several static ports.
A pitot–static system is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft's airspeed, Mach number, altitude, and altitude trend. A pitot–static system generally consists of a pitot tube, a static port, and the pitot–static instruments. [1]
As all information from the sensors is transmitted electrically, routing of pitot and static pressure lines through the aircraft and associated maintenance tasks is avoided. [ 5 ] In simpler aircraft and helicopters, the air data computers, generally two in number, and smaller, lighter and simpler than an ADIRU, may be called air data units ...
A pitot-static system generally consists of a pitot tube, a static port, and the pitot-static instruments. [5] Errors in pitot-static system readings can be extremely dangerous as the information obtained from the pitot static system, such as airspeed, is potentially safety-critical. Several commercial airline incidents and accidents have been ...
The basic technology of the pitometer log is similar to that of the pitot tube on an aircraft. Typically, the pitometer has a long tube that penetrates the ship's hull near the keel. The part of the pitometer protruding from the ship is sometimes called a pit sword or rodmeter. This tube usually has two openings: one facing the direction of ...
An air data computer with inputs of pitot and static pressures is able to provide a Mach number and, if static temperature is known, true airspeed. [citation needed] Some authors in the field of compressible flows use the term dynamic pressure or compressible dynamic pressure instead of impact pressure. [3] [4]
