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]
FHA results are normally shown in spreadsheet form, with columns identifying function, failure condition, phase of flight, effect, hazard classification, DAL, means of detection, aircrew response, and related information. Each hazard is assigned a unique identifier that is tracked throughout the entire safety life cycle.
EICAS typically includes instrumentation of various engine parameters, including for example speed of rotation, temperature values including exhaust gas temperature, fuel flow and quantity, oil pressure etc.
A central part of the openEHR specifications is the set of information models, known in openEHR as 'reference models'. [6] The models constitute the base information models for openEHR systems, and define the invariant semantics of the Electronic Health Record (EHR), EHR Extract, and Demographics model, as well as supporting data types, data structures, identifiers and useful design patterns.
Maintenance resource management (MRM) training is an aircraft maintenance variant on crew resource management (CRM). Although the term MRM was used for several years following CRM's introduction, the first governmental guidance for standardized MRM training and its team-based safety approach, appeared when the FAA (U.S.) issued Advisory Circular 120-72, Maintenance Resource Management Training ...
The electronic health record (EHR) is a more longitudinal collection of the electronic health information of individual patients or populations. The EMR, in contrast, is the patient record created by providers for specific encounters in hospitals and ambulatory environments and can serve as a data source for an EHR. [7] [8]
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.
