You'd probably be looking at 2-300 litres at a guess. Depends on the contaminant and the rig operator.
In the UK you're more likely to use Type 2 or Type 4 fluid.
Is there anyway i can find out what mixture to use for a freezing point of 10c below OAT?
I do use this app called DeIcing holdover app for IOS.
if using Type 4 Fluid can this be used as a Step 1? Reason i ask, I was on a EZY flight from EDI last Saturday morning at 06:45 and during takeoff roll - green fluid (type 4) came off the wings at high speed as it should. During boarding i seen no de-ice truck. So would this have been done early morning by ground engineers?
