Having passed my GFPT about 6 months ago the only thing I would add to the above comments is RELAX RELAX RELAX ....and yes, not an easy thing to do!. I received a "You can obviously fly, just relax !" from the tester.
This is a sign of an excellent testing officer. Probably not a CASA employee.
In twenty years time, when you maybe become an ATO, make sure you remember this.
Wrt short field landings - absolutely agree with other posters, they are a fallacy and don't exist in GA aircraft. It doesn't matter what graph you look at in the POH, the LDR is calculated with a 50' threshhold crossing and 1.3 Vs. Why on earth are CASA expecting you to demonstrate something other than this?
Another example of where CASA don't even understand what they are requiring people to demonstrate.
Short field landings with less than 1.3 Vs protection and less than 50' crossing heights came from military applications and have no place in CASA flight tests.
