Radio failure IFR
Hello
I was just reading again the general procedures to be completed in case of radio failure.
I was reading: "Proceed according to the current flight plan route to the appropriate designated navigation aid or fix serving the destination aerodrome and, when required to ensure compliance with 5), hold over this aid or fix until commencement of descent".
What i find confusing is the term: "the appropriate designated navigation aid or fix serving the destination aerodrome".
What do they mean with that? Is that a point in final? The IAF, which is not neccesarily in final?
Who can explain a bit?
