LeadSled,

Not quite that simple. The requirement for 6000lb plus aircraft has for many years involved a modest OEI climb capability .. for the present regs (23.67) this is a respectable requirement. The problem is with the below 6000lb twins where it is all downhill ....

Most Ozzies will be aware that the Shrike Commander, eg, runs at a higher weight here than in the US as the Australian OEI climb requirement under ANO101.22 was less restrictive than the FAA requirement .....

While the manufacturer will always go for the best conditions to test (so that, near invariably, climb testing is done in a very stable weather pattern somewhere near dawn) the FAR 25 data is provided for a useful range of operating conditions .. the FAR 23 pilot gets not very much at all by comparison .. although the situation has been getting better in recent years ...
