Thanks for the responses people, all very helpful... keep them coming!
Here's my input:
CPL F170:
"What are the VFR minima for getting in and out of the zone (class D) and for the rest of the flight (class G)?"
"What action would you take in the event of a gear failure upon return to the circuit?"
CPL Initial Skills test:
"What are the VFR minima for getting in and out of the zone (class D) and for the rest of the flight (class G)?"
"I see from your perf. calculations that you have plotted the aerodrome pressure altitude as being sea level [test was taken at Bournemouth which is 38' AMSL on a day with AD QNH1026]. Would you have plotted any differently had today's pressure been less than 1013?" He wanted to see understanding that on a day when prevailing atmospheric pressure was less than standard ISA conditions that the AD pressure altitude was now above its real level. eg. QNH1003 puts Bournemouth roughly 300' higher than on a day of QNH1013. BUT VERY IMPORTANTLY that you can NEVER plot below sea level on the perf graphs - this is extrapolation and not accounted for in the charts' accuracy.
