The engine pressure ratio (EPR) is the total pressure ratio across a jet engine, measured as the ratio of the total pressure at the exit of the propelling nozzle divided by the total pressure at the entry to the compressor. [1] Jet engines use either EPR or compressor/fan RPM as an indicator of thrust. [2]
No version of the Boeing 737 has EICAS. The Boeing 717 has CFDS, as it was originally a McDonnell Douglas product. The Embraer ERJ family and the Embraer E-Jet family have EICAS. The Bombardier CRJ and the Bombardier CSeries have EICAS. The Fairchild-Dornier 328JET has EICAS. The COMAC ARJ21 and the COMAC C919 have EICAS.
In May 1996, the FAA Aviation Rulemaking Advisory Committee (ARAC) was tasked with a review of harmonized FAR/JAR 25.1309, AC 1309-1A, and related documents, and to consider revision to AC 1309-1A incorporating recent practice, increasing complex integration between aircraft functions and the systems that implement them, [20] and the ...
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
ECAM is a series of systems designed to work in unison to display information to the pilots in a quick and effective manner. Sensors placed throughout the aircraft, monitoring key parameters, feed their data into two System Data Acquisition Concentrator (SDACs) which in turn process the data and feed it to two Flight Warning Computers (FWCs).
Control panel for a Boeing 737-800 ECS. In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers.
But EPR had to cut its dividend during the pandemic. The big culprit was its movie theater exposure, as movie chains weren't in a particularly strong state entering the global health crisis.
AS9100 Revision D (2016), Quality Management System – Requirements for Aviation, Space and Defense Organizations The update of AS9100 from revision C to D includes the full text of ISO 9001:2015. In addition to aligning the structure of the aviation, space and defense requirements to the new structure of ISO 9001:2015, the following key ...
