You are correct!

Satcop 15th August 2008 07:55

I wrote to my regular users (A109, AS355, B206, EC120, EC135, EC155, and S76) asking them if they required AL48, not one replied. I assume that they do not need it or are making their own arrangements.

Thanks satcop and everyone else,looks like ill be supplying JET A1 without AL 48 and leave it to the operators to sort it themselves

Shytorque, I think you'll find the 76 does need AL48/ ANother additive below +4 degrees. The C++ flight manual had an error which should have been corrected by now. It's an airframe rather than an engine limitation.

Does anyone know the lastest as to when the fuel suppliers will stop adding FSII? I'd heard that at Newcastle this will be the case soon, if it isn't already and do people plan to fly around with cans of Prist in the cab?
I've never had to use it but have heard that it not the nicest stuff in the world to handle.
Basically just wanted to know what people are planning to do,the ones without fuel heaters that is!

Jet A1
 
Were still selling jet A1 with al48 supplied by air total but have been told that after xmas they will not be supplying it with AL48,quoted £6.000 +vat to have an injector fitted ,think ill just change the filters more often.

FSII & certification
 
Not sure of this, but I believe that some helicopters are certified on the basis that fuel shall contain FSII. My Enstrom 480B is one of these. I have been told by the manufacturer that FSII is not required for technical reasons, but because the certification was done with FSII, it is now called out in the FM as "required." Given this, it would seem that without FSII the acft is not considered airworthy under FAA regs; if so this would have implications for insurance coverage if operated without , as well as other unhappy implications. Any brilliant insights?

do people plan to fly around with cans of Prist in the cab?
You may want to investigate the toxicity properties of Prist before doing so. I looked at this a few years ago wrt carrying Prist in the pressurized cabin of a turboprop airplane, and after reading what foul stuff it can be, decdided that carring it in the cabin wasnt the best idea.

We were informed last week that Oxford no longer supply fuel with FSII.

Just to add my two-penneth!

PRIST is HORRIBLE stuff!!!! I wouldn't touch it personally. Although most of the anti-ice additives are pretty dangerous, PRIST seems to be the worst.

If I remember correctly it can affect fertility (both male and female), damage unborn fetuses and that is just the bits I remember, we had a few people refuse to use it just down to what they read on the Safety Data Sheet!!!

I must admit I'm not keen to carry cans of Prist around but I have been assured that the aerosol cans are are safe enough in the aircraft (unpressurised) so long as they haven't been discharged. i.e don't use half a can and then throw it back in the boot.
I'm not keen to use the stuff at all and it seems neither is anyone else, I have heard that in the states and Canada firms use it all the time, is there anyone out there who does use it on a day to day basis who could offer some feedback?

Incidentally our FM(Bo105) states an anti-ice additive should be used to assure consistent starts at temperatures below +4c especially if the engine has been allowed to cold soak, it goes on however, to say that once started Jet A1 will run the engine satisfactorily down to -32c...........so providing it's been in a warm hangar say before you start it does that mean you don't need the anti-ice additive?

Cant comment on Canada, but in the US, in my experience, it is rare to need to add Prist from a can. Most fuel suppliers either sell only fuel pre-blended with Prist, or have an injector system on the fuel truck that adds Prist as the acft is fueled. If one is fueling out in the boonies, say from drums, might be a different story.

Air BP AL48 bulk supply locations are Cranfield, Goodwood, and Fairoaks, plus several commercial helicopter company bases.
