DE-ICING / ANTI ICING

[chrispler]

Hi All,

I am looking for infos on DE / ANTI ICING of Aircraft. Is there an offical list that shows required litres per aircraft type e.g. Learjet 60. Thanks a lot.

Try this ICAO document (http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CFkQFjAB&url=http%3A%2F%2Fwww.bazl.admin.ch%2Fdokumentation%2Fgrundla gen%2F02643%2F02644%2Findex.html%3Fdownload%3DNHzLpZeg7t%2Cl np6I0NTU042l2Z6ln1ae2IZn4Z2qZpnO2Yuq2Z6gpJCDe316fmym162epYbg 2c_JjKbNoKSn6A--%26lang%3Dfr&ei=yMPqUP-9FMSHhQfIu4HwBA&usg=AFQjCNFips8n8J67YMXrLtZeNriAJG24_Q&sig2=oZAwQJisp6iANJNn1ebtnw&bvm=bv.1355534169,d.ZG4), for general information which I always find helpful. It may be out of date. Also note EASA SIN 2008-29.

Otherwise manufacturers' data sheets would give answers, such as this one (http://msdssearch.dow.com/PublishedLiteratureDOWCOM/dh_08ac/0901b803808ac175.pdf?filepath=aircraft/pdfs/noreg/183-00024.pdf&fromPage=GetDoc). And company manuals/procedures.

AFAIK there is no minimum or maximum # of litres, just clean wing concept. we pay 9$/type1 and 12$/type 4. I have had a few 10,000+ sprays. I would prefer to cancel, but the big giant heads in YUL think different

Here In Canada we have an in depth program that requires training on an annual basis. It is quite complex more than most Aircrews realize unless you operate regularly in Icing environment.

Anyways have a look this should answer most of your questions.

ps: here's a link I hope it works first time I try to attach one !!

Bombardier have a large collection of information under "Winter Operations Awareness and Training" This area does not require a password or log in.

No idea if this covers the information you are after. You could ring up your Tech rep and ask, I've always found the Bombardier Support first class.

Uk CAA website takes you to this very good course.

Aircraft Icing Training - Courses (http://aircrafticing.grc.nasa.gov/courses.html)

Not that it answers your question.

Its all in the hands of the person on the spray.

Some seem to be able to do the job with minimal amounts used and others are liberal as you get.

I have seen 2 bills for wings and tail on the same aircraft different shifts and there has been a 25% difference in usage. We reckoned one bloke was on commission.

As soon as you ask for the truck you just have to grit your teeth and wait to see if you get raped or not.

Beware that many are used to deicing Airbus and 737s and have a minimum dispense quantity which in the case of Eindhoven was 220 liters.
We had snow on wings and tail of a Citation! Tail was too high to get to and snow had frozen onto the wing from roots to 10 feet out either side.
The aircraft was dripping in the stuff by the time they had finished and we had a bill for 1000 Euros :{

These weeks we had to deice a couple of times (deice only, no anti-ice), and in a mid cabin biz jet similar to the lear 60, cleaning wings and tail we used in both cases about 90 litres... 50/50 concentration, type II.

They're out there....:{

Check aea.be
You will find just the list you are looking for!

We developed our own program.

You have two choices -

1- You take the square root of the camber of the wing, divided by cubic inches squared of ice accumulated, multiplied by tire pressure gives you grams/litres required of de ice fluid if applied at 90 degrees. For every off angle degree applied then you take the fluid required multiply by stall speed divided by lav capacity squared to get the new number.

2- You use whatever fluid is required to blow off all the ice.

[Dufo]

We use method #1 for the last 2 years and managed to save 27,3% on deicing.

You guys bring up a good point. Am I better off with the peanut gyro STC for $50,000, gives me more time in the dark to get down, but the bigger battery, hence more weight, thus being able to carry 1 lb less ice, increasing my ref by .0001 kts?
