That explains most of the stuff which confuses me.
One more question. Let say I am already in 25 miles radius from radio fix which is used to calculate MSA, I checked MSA and its below altitude I should intercept IF for straight in approach, so I should be terrain-safe. I am flying RNAV equipped aircraft which can easily guide me to IF without any procedure turns, racetracks, whatsoever.
Can I ask ATC in non-radar environment for permission to make "straight in approach" via IF regardless of meteorological condition?
Or such a shortcut would be legally authorized only if there are conditions required for "visual approach"?
