Regarding W+B being "done".... Does this mean that when ramped you must already have completed documents showing this?
This really is something that folks should have off pat. I guess it's a bit like most things which we don't do all the time .. we tend to forget the details ...
The answer is, "it depends".
In summary .. do have a read of the following ...
(a)
CAO 20.16.1.
para 3 - aircraft must be loaded iaw the approved loading system if one is specified. This will be approved either by a CASA delegate or a WCO. If a loading system is not required there should be a statement in the weigh data to that effect.
If your aircraft is a simple machine and has a complicated loading system, you might like to get that changed to simple load rules which are of the form .. load this row then that row with similar prescriptive rules for the cargo and fuel. The advantage for PVT lighties is that you don't need to have done any specific paperwork .. but do make sure you are loaded iaw the load rules.
para 5 - most heavies and RPT have to have a completed load sheet. For most aircraft this probably will be a trimsheet style of loading system. Again this will be approved either by a CASA delegate or WCO.
(b)
CAO 20.16.2.
This CAO covers cargo etc. Details of how cargo should be carried should be as approved either by a CASA delegate or an appropriate Industry engineering AP.
(c)
CAO 20.16.3,
You should be familiar with this CAO and, probably for the airshow where folks might be taking the kids, para 13 for the ankle biters.
There are some further bits and pieces in CAO 100.7 but that is directed more at the engineering folks and the details should have been migrated to the 20.16 bits.
Overall, you should find that the ramp checks are pretty straight forward for the majority of cases.
However, do keep in mind that CASA is checking for regulatory compliance .. so do the "hello, officer" thing with a smile .. same as when the flashing blue lights request you to stop while driving ... simple people interaction 101.
W&B, you just need to prove that your operating within the limits for GA
Not quite .. see above ...
