Analys av avisningsprocess i syfte att resurseffektivisera : Processkartläggning med potential till Lean Service
A study made on streamlining the use of resources in aircraft de-icing and the
potential benefits of a Lean Service – In cooperation with Aviator stationed at Arlanda
The de-icing process of aircrafts consists of two steps; first part is to remove the ice
build-up called de-icing and the second part is to prevent further ice formation called
To remove the ice build-up, the affected areas are sprayed with a mixture of hot
water and glycol, this melts the current ice build-up while the glycol keeps the thawed
water from re-freezing. The second step consists of applying an anti-icing agent which
keeps the craft free of ice build-ups while on the ground. The anti-icing agent is
designed to grip the surface and prevent ice build-up untill the aircraft reaches enough
speed where water is not able to withstand the aerodinamic drag and risk ice
build-up. The drag also removes the anti-icing agent and the surface is clear of any
liquid that may prevent air capability of the aircraft.
This thesis work is generated from the observations and interviews of the operators
and shows that the amount of time and fluid varies depending on both experience and
ability. Efforts in standardization can shorten the learning curve and improve overall
commitment, also aircraft materials and designs are under constant development
which an improved de-icing process can take advantage of.
To achieve these goals, this thesis have applied a Lean methodology and how other
service industries have utilized Lean.
Aviator will from this thesis obtain suggestions of more efficient way to conduct their
de-icing operations, improve the environment for their employees and a reduction of
used chemicals which will improve Aviators green footprint. Important suggestions
includes standardization of procedures and expand their scope of data documented
during operations. Introduction of Lean will simplify the process towards continuous
improvement and secure the qualitatively measurements and help Aviators company
vision to be the worlds greatest provider of aviation services.
