If your group looks after the aeroplane, changes the oil often, pre-heats it in the winter and flies it regularly it might go on for a very long time
Could someone explain what is involved in 'pre-heating', and when you would need to do it to an aeroplane?
I have worked in North-West Canada for a few winters and when possible we would plug in our trucks overnight to stop them freezing up (there was a special plug in the grill) but we were talking temperatures of -20 to -40 deg C ... and colder!!
