Health & Usage Monitoring (HUMS)

HUMS processes and analyses the complete suite of vibration and helicopter data. It also helps to trend, diagnose and predict the health of helicopter systems.

HUMS helps to plan preventative maintenance; enhance quality and safety; and reduce costs of helicopter operation.

Our HUMS system primarily senses the vibration of the main reduction and accessory gearboxes, main and tail rotor as well as engines.

We have over two decades of in-service experience.

How does HUMS help operators?

The maintenance data is analysed to:

  • detect incipient defects in major components before they can hazard the safety of flight
  • detect the exceedance of a range of limitations
  • increase reliability of many items of equipment by minimising airframe vibration

A longer term goal (from the analysis of data over a long period) is to base component replacement on condition and usage rather than simply on hours in-service – this reduces unnecessary maintenance costs. This concept is called Condition-Based Maintenance (CBM).

What HUMS includes

For each helicopter, the Meggitt HUMS typically comprises:

  • on-board electronic unit, usually referred to as data acquisition and processing unit (DAPU)
  • accelerometers (multiple)
  • remote charge converters (RCC) and associated cables
  • rotor speed and position sensors
  • pilot interface panel (PIP) or a control and display unit (CDU)
  • ground support software (GSS) supporting the display and analysis of acquired data, as well as the configuration of equipment
