Mogga 04, let's see, tell your piss poor instructor the following is the general GA rule:
Despite Aussies being a fat bunch, all your pax will be 77 kg or under. You will tell some to suck in their guts and put them down as 60. Given the propensity of "more is less" that most folk adhere to (never any room in them overhead lockers) you will stuff their baggage anywhere it fits just to get it out of sight (baggage, what baggage). Following this you will fudge the paperwork so everything tallies.
You will then top off the tanks with "just a little bit more" and rely on the Barons HP and the cool morning air to get you out of YMEN.
When you arrive at YKII you will park right smack bang in the way of everyone, (it's just a remote strip right?) and you will hope the tail stays off the ground. Finally after unloading all your passengers you will retire for the night at the pub where your tales of bravado will go down well with the locals.
With a hangover that is furrowing your brow you will repeat same the following day, allowing a little extra room (under the seats perhaps?) for all that cheese and beef the punters have purchased. This time the YKII winds will assist with the take off figures.
Don't worry about the life jackets, you got two engines right?
Enjoy!
