Reverse,
The procedure originates from the Military, the Australian Military use it.
There are questions about hitting a hill at 236 KIAS, on a one to one descent, there is not likely going to be terra-firma in that area, how would a aircraft out climb that in VMC ?, the only concern I could think about is from the west into YBCS.
Turn backs are relatively common in newer aircraft, Flightsafety teach it for the C208.
To expand on one point, 7,000 AGL and 7NM is quite critical, if you went to 10,000 AGL / 10nm, you'd bust VNE.
I'm with morno, its great fun, in training.
