De-ice TYPE I fluid
I’m interested in knowing what is the usual FLUID / WATER ration when carrying out a Step 1 de-icing if there is contamination on the upper wings (hoar frost) during the night but NO precipitation falling?
Would 100/0 be good enough or 75/25 ?
Also how many litres does it take roughly to remove all contaminates from a 737 NG wing?
