Canberra is for the 35 ILS-Y:
MIN MAP GRAD 5.0% TO 3200FT THEN 2.5%
One of the steepest, if not steepest in Southern Hemisphere
Don't get too excited UITA. Quite a few
airstrips in PNG have slopes greater than 5%, and that's the strip. You don't even want to think about a go-round. And who knows what they get up to in the Andes, the South Is of NZ, Kenya, Zimbabwe, Indonesia etc.
5% = 2.86 degrees, i.e. slightly less than the ILS you just came down. To put it in perspective, the 34L Katoomba One Departure out of Sydney requires a gradient of 5.9% to 2500' and a full [max ZFW] 747 going to Singapore will do that at reasonable temperatures [up to 30 degrees at least] on 3 engines.
