Some old text from Boeing:-
“Investigation has shown that both Type I and Type II aircraft ground de-icing/anti-icing fluids cause a transitory lift loss and drag increase. Aerodynamic effects of most of the older generation (1987 and earlier) Type II fluids (most of which are no longer commercially available) were found to be significantly larger than those of Type I fluids. New formulation Type II fluids, developed in 1988, have aerodynamic effects no greater than those of Type I fluids, while providing significantly longer holdover times during which they protect the wing from ice, frost and snow. Evaluation of the effects of both fluids on the performance of all Boeing jet transports indicates that, with the exception of the 737-100 and -200 Non-Advanced for which performance adjustments are recommended, sufficient performance margins are available to offset the effects of the fluids.” Boeing Airliner Oct 1989
Although the newer fluids / aircraft types do not require (recommend) performance adjustment, there is still some performance loss due to the anti-icing fluid – margins are reduced.
Of the data which I saw from several manufactures’ test flights (type II / IV circa 2000), most of the performance loss was judged acceptable. However, IIRC some turboprop manufacturers did make a performance adjustment, but this might have been due to other icing / anti-ice fluid factor.
