MEL DDG CDL confusing!?
dear all pilot ,
I searched this forum and there isn't any clear explaination of MEL DDG and CDL.
What I used most is MEL , and when can I use DDG and CDL as a pilot ? do I need to ?
also have the confuse of when you use MEL. just say examples .
After door close , you have one pack inop.
do you have to use MEL? I mean HAVE TO.
After engine start , you have one pack inop. do you have to use MEL?
and under the examples above , when you need to use CDL or DDG?
I know CDL is for configuration , so i think we can ignore it .
still confusing of this three ...........
