Thanks for the reply. I think we might not be discussing the same thing.
If I understand the Airbus article properly (
http://www.airbus.com/store/mm_repos...6_low_fuel.pdf ) then the 'minimum engine inlet temperature' is the minimum temp. the fuel should be AFTER passing through the 'oil cooling system', i.e. the fuel is about to be burnt.
To quote from the article, paragraph entitled Minimum Inlet Temperature,
Engines have an oil cooling system at their inlet, which uses the arriving fuel as a heat sink, thus warming it. Various system architectures and hardware leads to a varying specification of the minimum temperature that a given engine type can cope with.The minimum temperature is expressed as a margin versus fuel freezing point - the minimum engine inlet temperature is the actual fuel freezing point with the manufacturers margin added to it (see right-hand table).
Of course, I might be completely misunderstanding the terms used and their meaning, in which case I'll find a dark corner .......
