Proactive decision-making with Engine Health Monitoring (EHM)

Powered by innovation, Rolls-Royce’s Engine Health Monitoring (EHM) advancements drive our services to be predictive rather than reactive to help our customers before issues arise. Included and covered by CorporateCare® Enhanced.

Data from on-board sensors recorded and transmited for analysis

Engine data analysed after each flight to detect any abnormalities

Diagnose the cause of any abnormalties

Rolls-Royce provides timely recommendations to keep your aircraft flying

EHM optimises maintenance and addresses potential issues before they become a possible Aircraft on Ground (AOG) scenario

What is Engine Health Monitoring (EHM)?

Engine Health Monitoring (EHM) tracks on-wing performance using on-board sensors as our way of analysing data from each engine after every flight, whether snapshot data or our more advanced EHM with continuous data, to achieve the best possible engine availability and keep your aircraft flying as often as you need it.

What data does EHM collect?

Standard EHM

Snapshot data comparing left-hand and right-hand engine
5 data points per flight
Step change or long-term trend determination

Advanced EHM

Continuous data that compares the EEC
CHA and CHB
LRU continuous data
Able to receive one data point per second
Early emerging issue detection

Developing Capabilities with EVHMU

2-way communications on-ground to reconfigure data transmitted
HF vibration data from the entire flight (once on ground)
Livestreaming of ground runs in real time

Advancement of EHM

The Pearl engine family expands its capabilities by showcasing Rolls-Royce’s IntelligentEngine vision with its Engine Vibration Health Monitoring Unit (EVHMU).

Advancement of EHM image

With its state-of-the-art EVHMU, the Pearl family features a step-change in ‘on-wing’ engine intelligence to deliver best-in-class engine availability. It is enabled to be connected to the Internet-of-Things, it can provide instant access to over 10,000 engine performance and health parameters with unprecedented levels of data quality, including:
