Operability
Encyclopedia
Operability is the ability to keep an equipment, a system
or a whole industrial installation in a safe and reliable functioning condition, according to pre-defined operational requirements.
In a computing
systems environment with multiple systems this includes the ability of products, systems and business processes to work together to accomplish a common task such as finding and returning availability of inventory for flight.
In the gas turbine engine business, engine operability is the ability of the engine to operate without compressor stall or surge
, combustor flame-out or other power loss. Operability engineers work in the fields of engine and compressor modeling, control and test to ensure the engine meets its ignition, starting, acceleration, deceleration and over-speed requirements under the most extreme operating conditions.
Operability is considered one of the ilities
and is closely related to reliability
, supportability and maintainability
.
Operability also refers to whether or not a surgical operation can be performed to treat a patient with a reasonable degree of safety and chance of success.

In the gas turbine engine business, engine operability is the ability of the engine to operate without compressor stall or surge
Compressor stall
A compressor stall is a situation of abnormal airflow resulting from a stall of the aerofoils within the compressor of a jet engine. Stall is found in dynamic compressors, particularly axial compressors, as used in jet engines and turbochargers for reciprocating engines.Compressor stalls result in...

Reliability engineering
Reliability engineering is an engineering field, that deals with the study, evaluation, and life-cycle management of reliability: the ability of a system or component to perform its required functions under stated conditions for a specified period of time. It is often measured as a probability of...

Maintainability
In engineering, maintainability is the ease with which a product can be maintained in order to:* isolate defects or their cause* correct defects or their cause* meet new requirements* make future maintenance easier, or* cope with a changed environment...
