In light of the SR22 tragedy in Brazil, I have a question.?

Question

How can you, as a pilot, tell if the line guy is pulling up in the right truck without reading the word AvGas on it? This worked for pumps too. (Looking for numbers.)

Answer 1

You always visually check the fuel in a strainer before flying, and you smell it.  AVGas and JetA differ greatly in both smell and sight.

Answer 2

there was a case where a av gas plan was filled with jet fuel.  the plane will still run but needs to have the engine overhauled.

the number coding for av gas is 1203 in a red diamond...my fueling boss who taught me how to dive the truck on the field was in tune about this number.

Noses are different for jet versus av gas....av gas can be filled into tank like normal car and Cessna but The jet fuel needs to be locked on.

but if the wrong gas is in the truck you will never know without sum-ping the fuel.

remember you colors

blue /green

red

clear

fun fact jet fuel not flammable only the vapors - told by college proff...supposedly chief flight line instructor at airline took match and put in pan of fuel and did not ignite.....do not try

Answer 3

black or blue decal denotes the fuel. And you should NEVER be able to get a jet A nozzel into a 100LL filler neck due to the different nozzles to prevent such a disaster.

smell it when in doubt. or have the FO do it.

Answer 4

all the fuels have different colors and smells. thats why you should always sump your tanks. 80 octan is red, 100ll is blue, jet-a is clear to a straw color.

Answer 5

You can't. FBOs have wrongly filled trucks with Jet A instead of avgas.
