What should the IAM operator include in its operations manual regarding de-icing and anti-icing on the ground?

The IAM operator should include de-icing and anti-icing policy and procedures for aircraft on the ground in its operations manual, including descriptions of the types and effects of icing and other contaminants on aircraft while stationary, during ground movements and during take-off.

What information about fluid types must be given in the de-icing and anti-icing procedures?

A description of the fluid types used should be given, including proprietary or commercial names, characteristics, effects on aircraft performance, hold-over times, and precautions during usage.

According to AMC1 UAM.OP.VCA.250, what is the regulatory basis for the de-icing and anti-icing ground procedures?

The regulatory basis is ED Decision 2025/010/R, as stated in the section header.

Does the section specify any particular hold-over time values for de-icing fluids?

No, the section only requires that hold-over times be described for each fluid type; it does not specify any particular values.

In the context of ground procedures, what are the three operational phases during which the effects of icing and other contaminants must be described?

The three phases are: while stationary, during ground movements, and during take-off.

What is the publication date of the ED Decision referenced in this AMC, and does the section state an applicability date on or after that date?

The publication date is 2026-03-27. The section does not state any applicability date, so no applicability date question is applicable.
