Gentleman,
Let's cut to the chase. Let's set the scene:
Can an aircraft that is visual at NIGHT with the airfield, not even one cloud in the sky, descend below MSA at about 10 miles and join base leg and position on a, lets say, 5 mile final?
Let's say that the aerodrome has no radar facilities but does have a published NDB/DME procedure.
Is it a Yes or does commercial expediency get a slap on the wrist?
It would be nice to clarify as I'm still trying to find a definitive answer not a definite maybe!?!
