Sofema Online (SOL) www.sofemaonline.com considers typical aircraft ground De-Icing /Anti-icing procedures

Introduction

The necessary inspections and communications can be made beforehand at the gate whereas, at remote/centralised de-icing, the necessary information must be informed to the de-icing crew in another way (e.g. coordinator communication).

The determining of the need for de/anti-icing can be made by other qualified persons, not necessary the de-icing crew.

An aeroplane shall not be dispatched after a de-icing/anti-icing operation until the aeroplane has received the following visual check by a trained and qualified person.

      »  This check shall cover wings, horizontal stabilizer, vertical stabilizer, and fuselage.
       »  This check shall also include any other parts of the aeroplane on which a de-icing/anti-icing treatment was performed according to the requirements identified during the contamination check.
       »  The check shall be performed from points offering sufficient visibility of all prescribed surfaces (e.g. from the de-icer itself or other equipment suitable for gaining access).

SofemaOnline (SOL) www.sofemaonline.com looks at Aircraft De-Icing /Anti-Icing Basic Criteria

Introduction

De-icing Fluids are typically ethylene glycol, or propylene glycol-based fluids containing water, corrosion inhibitors, wetting agents, and dye.

Anti-icing Fluids are similar in composition except that they also contain polymeric thickeners. They are formulated to prevent the formation of unabsorbed frozen contamination for a longer period of time than de-icing fluids; however, the protection is still for a limited period of time. (refer to “Hold Over Time” for details related to useful time availability.)
