I agree with Jonty, JSI is a special place. Short, narrow runway with a hump, sat on made up ground between two islands. It's not the place where you do an hour in a Sim and off you go. All approaches are are low and "exciting".
It would be useful if anyone commenting on this thread started their post by stating if they had trained for or operated an aircraft into JSI. These people I will happily listen to. The rest should stop criticising something they don't fully understand....
