A good subject, as you say for this time of year - in the tropics.
Perhaps you could have added the requirements for Inter and Tempo as well which of course have to go on top of your alt cruise requirement, with the usual reserves transferred to each alt after each arrival.
The only thing that I would suggest is that for all controlled A/D destinations that you have in your ops manual a selection of ALA's to spend some time in. Remembering of course the mosquitos as old mate above says and don't forget the lightning.
Think of the money that you will save your company while you play monopoly with your clients in a gauzed in tin shed instead of orbiting at many dollars per hour.
On one occasion when I was waiting very tediously to get out of Kununurra to go home as a PVT F/W flight, quite some tims ago, the only amusement that I had for about three days was to saunter up to the FSU at daylight, check the wx and watch the twin F/W drivers try to get plans accepted.
They might be wishing to fly say 4 people and not much baggage to Darwin.
Simple, one might say, have a look at the map, it's not far after all.
Only a couple of small probs. There were only four A/D's (incl KU) apart from Darwin open north of Alice Springs. The others were Katherine, Gove and Tennant creek.
Usually after 10.30 am Local, you would need to add 60 minutes for Tempo at KU, DN, KN or TN (Tindal) and Gove and 30 for Inter at TC. The prospects for doing anything legal thus diminished rapidly. One day there was Inter at the Alice as well.
It was amusing to watch these guys try to stretch the usual 330 minutes or so of the Baron.
