EC135 Technical Question
Folks, I thought I knew the answer but now have doubts. The lack of an accessible FLM means I appeal to you.
When you use the overhead panel switch to test the Warning Lights, are you just testing the red light bulbs or do you continuity check the full circuitry for each light?
This is mainly aimed at the Low Fuel warning lights. Are you “proving” the system or checking the bulb? I always thought it was a bulb check
