Makes me wonder how airlines managed to operate the aircraft in +40°C temps as occurred in South Aus, hottest I experienced in Whyalla was 49.4444°C.
I can remember 'hearing' of an occasion where a PA31 arrived at an airfield in SW Queensland, and the OAT on arrival read 52C, having just 50 minutes previously departed another airfield to the south of the aforesaid airfield where. it was alleged, that the Temperature was at a somewhat similar level.
Oh, and the thermometer out the back of the Pub read 55C. Or so the story went.
How indeed did they manage such a thing?
