CS 27 question
Hi ppruners!
In CS 27.955 Fuel Flow b) Fuel Transfer systems states:
If normal operatios of fuel system requires fuel to be transferred to an engine feed tank, the transfer must occur automatically ....
My question is: how EC135 managed to get through this point if the pilot needs to turn ON the transfer pumps to feed the supply tanks ????
I'm sure there is knowledge enough around ppruners to responde .... thanks in advance
