Information for Aerodrome and Aircraft Operators
De-icing is the removal of ice, snow and frost from the surface of the aircraft.
Anti-icing is prevention of build-up of ice, snow and frost on the surface of the aircraft.
De-icing/anti-icing procedures must be carried out exclusively by personnel trained and qualified on this subject. Companies providing de-icing/anti-icing services should have both a Qualification Programme and a Quality Assurance Programme to monitor and maintain an acceptable level of competence.
Operators should take account of the following:
The operator should provide procedures for ground handling agencies, engineering personnel and flight crew, detailing processes, duties and responsibilities for ground de-icing/anti-icing and associated ground handling tasks, such as intake blanking. De-icing/anti-icing techniques for intakes and undercarriage should be detailed. Those tasks contracted to ground handling agencies should be subject to regular quality reviews.
In the case of off-gate de-icing/anti-icing, the key elements to be considered are communication, inspection and records. The following should be considered for inclusion in procedures as applicable:
(a) The responsibility for determining the need for de-icing/anti-icing on the gate, and the means of communication to the commander.
(b) Establishment of two-way communication with de-icing/anti-icing ground staff.
(c) Key staff responsibilities, including post-treatment inspection.
(d) The procedure for ensuring deactivation of aircraft systems.
(e) The format and passing of de-icing/anti-icing codes.
(f) Ground and flight deck record requirements.
