Anti-icing additives in Jet-A1 (again)
The flight manual for my newly-acquired Enstrom 480 (RR 250-C20W) states that 'at ambient temperatures below 4 C, all fuels used shall contain anti-icing additive'. It also says 'avoid using anti-icing additives packaged in aerosol cans'.
I have read the various historic threads on this forum which touch on this subject, but with less and less availability here in the UK of Jet A1 with FSII/AL48 already added (at GA airfields), I am not clear about what other turbine owners/pilots do about this issue.
I am aware that more sophisticated helicopters have fuel heaters that solve this issue, but would like to hear from pilots who operate a similar type of helicopter about how they address this issue, if at all.
Obviously the risk of icing is much greater in the depths of winter, but am I being too paranoid about the risk of this happening?
