Clean Aeroplane Concept
Clean Aeroplane Concept
The Company has adopted the “Clean Aircraft” concept. This means that a take-off is not permitted with frost, ice, snow or other contaminants adhering to the lifting surfaces, flight controls or critical surfaces of the aeroplane. All fuselage vents, engine inlets, control surfaces, surfaces of the wings and horizontal stabilizer shall be free of any adhering contaminants.
The accumulation of frost, ice and snow (including freezing rain, water and ice pellets) on critical aeroplane surfaces will dramatically affect take-off, climb and flight performance.
Therefore, the removal of such contamination prior to take-off is a requirement and shall be strictly adhered to.
The only exception to this rule is that a light coating frost on the fuselage and up to 3 mm thickness of frost on the under-surface of the wing in the area of the fuel tanks that has resulted from cold soaking is permitted.
Fuselage areas in front of the cockpit windows have to be completely free of ice and snow.
Handling
Approved sub-contractors at each airport are used to perform the de-ice/anti-ice function.
However, all associated employees share the responsibility for ensuring that no aeroplane is dispatched unless it is completely free of frost, ice or snow.
The approved sub-contractors employ authorized and trained personnel familiar with critical aeroplane sections in general and with the equipment available. If deemed necessary, the Commander should inform the sub-contractor’s ground crew about specific ground and spray procedures for the aeroplane used.
Responsibilities
Commander
The Commander determines the need for de-icing/anti-icing. He is responsible for effective de-icing/anti-icing and retains overall responsibility for ensuring that all critical surfaces and components of the aircraft are free from contamination. His request for the treatment and the fluid mixtures used will always take precedence over locally recommended procedures.
The Commander may also rely on qualified person in making a determination as to whether the aeroplane is free of contamination or not. However, if a qualified person determines that the aeroplane is not free of contamination, then aeroplane de-icing/antiicing is mandatory.
If at any time prior to take-off, the Commander requires confirmation of the ice free state of the aircraft, he must carry out or order a visual inspection or return to the ramp.
Whenever de-icing/anti-icing has taken place the Commander must make an appropriate entry in the Aircraft Technical Log showing the start time, stop time, type of fluid, mix ratio and sign it.
Qualified Person
Qualified person is ground de-icing personnel or anyone who has received appropriate training in determining whether or not the aircraft is free of contamination (authorized engineer, etc). If any flight crew member or qualified person has determined that critical surface contamination is present, then aeroplane de-icing/anti-icing is mandatory. The handling agent is responsible for the availability of personnel equipment and fluids. All actions in connection with de-icing/anti-icing shall be coordinated with the authorized engineer (if present) and the flight crew.
Cabin Crew
While the Commander bears the ultimate responsibility for the safety of the flight, cabin crew shall have an awareness of their potential to contribute significantly to safety particularly during ground operation in icing conditions. On the ground cabin crew are often in the best position to observe the condition of the upper surface of the wing. Cabin crew are required to report to the Commander any concerns they have with regard to contamination of the wing surfaces or concerns they may have regarding snow, ice or frost. They shall also advise the Commander of any passenger concerns of a similar nature. In this situation the Commander, designated flight crew member, or qualified person shall conduct a contamination & post de-icing/anti-icing check to determine if the aeroplane is free of contamination.
