Thanks for that reference Brad. Useful info from a wonderfully drol presenter☺.
My question was prompted after I was simply scrolling through the MFD as tootled along in the traffic the other day and saw as I recall 96 degrees displayed and the outside temperature was supposedly 20c. Just wondered what sort of temperature would be "normal" once we get 38 degree days and times I'm maybe giving it a wee bit of stick up the hills in RNP on my way out to Bundeena.😉
