EC 135 - stupid question
Given "up to 59.5 kg" unusable if the forward transfer pump fails...
How about "no fail indication" (i.e. caution) of a forward transfer pump? No light? What's the possibility of this occurring?
Our EC 135 'seems' to transfer fuel normally until about 27 gallons. At that point, the supply tanks start depleting. I am told that other tail numbers have this same functionality? However, other ships reportedly use all their MAIN fuel to ZERO. The later seems normal. Correct?
Does your main fuel always go to ZERO - BEFORE the supply tanks begin to be depleted.
However, if during this anomaly (i.e., with supply tanks depleting as the MAIN fuel goes below 27 gallons), the forward, then aft transfer caution lights illuminate, would this not suggest that the forward and aft transfer pumps are functioning properly - but the MAIN FUEL indication is OUT OF CALIBRATION?
Thanks for your expertise.
