10 Questions to Ask When Buying a Health and Usage Monitoring System (HUMS)

January 21 2020


Foresight takes advantages of advances in sensor technology, edge processing, cloud architecture, connectivity, user interface design, and predictive analytics to deliver a next generation product.

We encourage you to ask these 10 questions if you are considering a Health and Usage Monitoring System:

1. Usability – can all member of your team use the system or does it require specialized interpretation from in-house or outside experts?

2. Full Functionality – does it offer rotor track & balance, flight data w/ exceedance monitoring, and engine performance in addition to mechanical system monitoring?

3. Availability – does the system provide software access from anywhere via browser/cloud architecture or does it require a specific aircraft-to-PC connection in order to be usable? 

4. Prognostics – does it provide a true predictive model (including component Remaining Useful Life) allowing you to optimize assets and better plan maintenance windows?

5. Specificity and Accuracy – on bearings, can it identify the difference between an inner and outer race fault? does it have a history of false positives?

6. Automation – does regime recognition automate acquisitions and is the data on the aircraft moved automatically to the software via WiFi/cellular? 

7. Updates – does the system have update-over-the-air functionality that insures bugs will be fixed and improvements made?

8. Weight and Installation Time – how much does the onboard system (including all mounting hardware and cabling) weigh? How long does the system take to install?

9. Validation & Self Monitoring – Does the system enable fault validation through raw signal processing waveforms and fleet comparison views? Does it monitor its own health?

10 .Certifications and Sustainability – is the system STC certified and can the provider show you certificates,  environmental testing, and instructions for continued airworthiness?
