Chapter 5 - Ground Crew Supplement

Qualified Fluids

17.  A list of qualified de-icing and anti-icing fluids and the HOT tables are included in the current Ground Icing Operations Update TP 14052E. If reliable holdover times are to be achieved, only qualified fluids, stored, dispensed and applied in accordance with the manufacturers' instructions are acceptable. The qualified fluids have undergone laboratory testing to quantify their protection endurance and to confirm aerodynamic acceptability during simulated take-off conditions.

18.  Qualified fluids have undergone laboratory testing to meet performance specifications and to confirm their aerodynamic acceptability. They have also been subjected to endurance time tests from which the holdover guidelines have been developed. Chemical property tests are also conducted. The operator is ultimately responsible for ensuring that only qualified fluids are used.

19.  It is expected that additional fluids will be qualified from time to time. Operators are encouraged to contact suppliers or manufacturers to determine the qualification status of any de-icing or anti-icing fluid that does not appear in the CBAAC. However, the operator will be required to prove that fluids not on the approved list have been properly tested.
