INTERIM REPORT – OPTIONS FOR CHANGE
EASA.2009.OP.21
Aerodromes
− Everyone involved in each step of the de-icing / anti-icing process must be trained,
qualified and aware of their responsibilities and duties (1.2).
− The infrastructure must enable and support de-icing operations.
− When planning to collect waste glycol, the whole chain must be considered (from ramp
to runway) and not only the place of de-icing / anti-icing (10.1).
− The de-icing / anti-icing coordinator (12.2.3) is responsible for controlling the
movement of de-icing / anti-icing vehicles on the ramp and remote areas.
Service Providers
− Everyone involved in each step of the de-icing / anti-icing process must be trained,
qualified and aware of their responsibilities and duties (1.2).
− De-icing / anti-icing providers should have suitable ground handling agreements in
place, with each operator, at each airfield, which detail the rules and procedures.
− Thickened fluids (6.1.5) are, in general, not heated when used as anti-icing fluids
because the viscosity will lower if heated. HoTs are determined using certain
viscosities. They are also applied undiluted if longer HoTs are needed (7.3.2.2).
− Type-I fluid should be used for de-icing to minimise the possibility of residue problems.
− One-step de-icing / anti-icing is generally performed with a heated un-thickened fluid
(7.2.1.1).
− Proper communication with flight crew and other ground crews is important; there
cannot be any doubt of the procedure, fluid used, holdover time, areas covered etc.
when communicating and verifying the process (7.4).
− The service provider should provide a coordinator(s) (12.2.1/2) for supervising
operations, communications and resolving misunderstandings.
− The coordinator is to verify and communicate the required procedures, taking into
account variations between operators’ requirements (12.2.3).
− Two-step de-icing / anti-icing is performed whenever the contamination demands a deicing
process separately (7.2.1.1).
Authorities
