PLovett, How ya doing
mate
To be totally correct, longitudinal spacing in Hobart is all to do with runway occupancy times for Jets. RWY12 (normally with a downwind component above 1000ft AGL) greater than 90% of all landings and takeoffs require backtracks. From touchdown to vacated can be up to 5 mins due to there being only two midfield taxiways.
Were full length taxiways available, Tower Approach could run the spacing down to as tight as 5NM. Surveillance has nothing to do with it. Add to that the fact that 99% of all traffic in to and out of Hobart operates with 66degrees of lateral splay, well you get the picture.
It is what it is.
