...Sadly there is nothing to stop CASA ramp checking anyone who commits aviation on a +40C + SL day and asking how you complied with the strict requirement. The short answer is you can't and they could, if they wished, send you the 'fax' and refer to the prosecutor.
And that gets us back to just how were the temperature defined for the ramp check ? ...the 'official' met which is not a now figure, or from the 'ambient' temperature taken somewhere near the aircraft at a particular time.
On a hot summers day if the aircraft is parked between a row of stifling windless hangers the temperature at the aircraft could be anywhere up to 10+ degrees hotter then if it were parked 50 metres away on the wind swept grass near, though not under, that shady tree. There is no fixed ambient temperature on an airfield.

The other mater is many of the temp charts for older aircraft were done before electronic temperature recorders were in common usage. Older temp gauges are a bit lazy, i.e. They only give an average temperature over a few minutes time frame and thus do not record every fleeting high temperature peak like the electronic temp gauges do. This is well seen with the current global warming idiocy where modern temperature 'records' recorded on millisecond recording electronic equipment is compared to the older temperature records recorded via lazy mercury gauges. It may be something CASA needs to look at as to how a pilot defines the temp to use.

I suspect even Rumpole could run rings around any ramp check temperatures if it were bought to court. At any rate, it would certainly put CASA square into the global warming 'issue'..
