I'm refreshing EC knowledge and I can't find an answer to my question:
Herr Balick (the one just under the god of EC135)
was my instructor for ground school and I made a note on Mast Moment Indication System:
"Caution range 50-66% yellow - NO TIME LIMIT"
Why did I wrote that as we can clearly find the accumulated time for both yellow and red MM range on VEMD?
I checked what I could find in the maintenance manual - found nothing except how to take it apart - so, does yellow "caution" range represent maintenance action after certain accumulated time or not?
Nothing in the FLM supplement also... except for the red markings - entry in logbook + maintenance action.
