Hey Aerotech
You forgot to start your post...In an inflight shutdown what does the 3 position switch on the EDP do..
You should try asking how something works rather than how it fails.
Do you know what the 2 position HYD EDP swith on other aircraft do? Do they Depressurise, cut off or both.
It seems silly to ask a question and not be able to understand the answer.
