- what is your understanding of "entry into a reversal is not practical"?
- what is your understanding of "increase operational flexibility"?
Well, I think the key to the riddle is in that little note:
when is the entry into reversal not practical- it's when you come outside the cone of 30 degrees of the centerline, in this case you initially need to enter the holding before you commence the reversal procedure. I think, in this case racetrack is more useful and does increase operational flexibility. I stand to be corrected though.
