Locate the EMU status light

With the Mastery battery switch on, check the EMU status

• EMUs are standard equipment in new R22 and R44-series helicopters purchased after January 15, 2020

• Helicopters with EMUs installed can be identified by the presence of their status indication lights

• EMU status is indicated by an amber light on the aft wall of the compartment under the pilot's seat

  • A steady (non-flashing) status indication is given for normal EMU operation

  • A fast flashing indication (4 times per second) is given if an exceedance has been recorded

  • A slowly flashing indication (once every two seconds) is given if a fault is detected with the EMU or one of its sensors

• The EMU receives power when the battery switch is on, so there will be no status indications with the battery switch off
