Based on the ASTM D1655 standard specification for turbine fuels, the only difference between Jet A and Jet A-1 is the freezing point. Max [min?] -40 degrees Celsius (-40° F) for Jet A and max -47 degrees Celsius (-53° F) for Jet A-1. Also, Jet A is widely available in the US (high latitudes).
From my understanding, if Jet A (with higher freezing point) is suitable in colder regions (e.g., the US), it should also be suitable in warmer regions (e.g., tropical countries), as it is already hard to reach -40 degrees Celsius (let alone -47 degrees Celsius) in tropical regions. Assume that both have the same altitude.
So, my questions are:
Are there any feasibility studies or research regarding usage of Jet A fuel in tropical countries? Please share!
Could someone provide information of the cost production differences between Jet A and Jet A-1?
Much appreciated guys!
