You have an incorrect assumption about new fluids sliding off surfaces more easily. The problem with the new ‘thickened’ fluids (some type 2 and possibly all type 4) is that they may not flow off surfaces as quickly as the older fluids. This was in part the problems with type 4. Turboprop / regional aircraft have lower takeoff speeds than the big jets. These operating characteristics may not match the assumptions in the fluid specification.
If you still operate BAE SYSTEMS aircraft, see their latest All Operator Messages and the excellent booklet called ‘Think Ice 2000’. Also available in Spanish ‘Piense Hielo 2000’. I think that there is also a new CD on Winter Ops.
The UK CAA planned a Winter Ops CD with emphasis on de/anti icing procedures – ‘Ice Aware’; anyone seen this or have details?
