 I have provision for two hydraulic instruments in my EFIS Blue Mountain EFIS
1), but have decided that there is no utility value to having them. I have
indicator lights for a positive DOWN and a pump light if the pump is running.
I have a button to press that tests the three indicator lights. I couldn't
think a any good reason to ask for more.
