Fuel types (divert) include Jet A1 (AVTUR), F34, F35, F44 (AVCAT). Which fuels are allowed for divert?

The key idea is that divert fuel must be fuel types the aircraft is certified to burn. Jet A1 (AVTUR) is the standard civil aviation kerosene, and there are additional approved kerosene fuels like F34, F35, and F44 (AVCAT) that some aircraft are certified to use as well. If the aircraft’s fuel system and engine control are approved to operate on Jet A1 plus those NATO/AVCAT fuels, then any of these fuels can be designated for divert. Since all four fuels are approved for use on the aircraft in question, the divert plan may include Jet A1 and F34, F35, and F44. Other options would be incomplete because they omit one or more fuels that the aircraft is certified to burn.
