Question 1

Conditions for tankering ?

Answer 1

Limit tankering to the applicable maximum mass minus 2000 kg, when;
- The entire flight can be completed with temperatures above 0 degrees; or
- Flight duration < 3,5 hours; and
- OAT – dewpoint > 4 degrees; and
- Destination OAT > 15 degrees;
In all other cases limit tankering to a landing fuel of 2000 kg in each wingtank.

Question 2

Conditions for take-off with CSFF on lower wing surfaces?

Answer 2

Takeoff with CSFF on lower wing surfaces is allowable provided all of the following conditions are met:
• Ambient air temperature is at or above +4°C, +39°F
• There is no precipitation or visible moisture (rain, snow, drizzle,
or fog with less than 1 mile visibility)
• Tank fuel temperature is at or above -16°C, or +3°F
• All leading edge devices, all control surfaces, tab surfaces, winglet surfaces, and control surface balance panel cavities must be free of snow, ice and frost.
If all of the above conditions are not met, takeoff with light coatings of frost, up to 1/8 inch (3 mm) in thickness, on lower wing surfaces due to cold fuel is allowable; however, all leading edge devices, all control surfaces, tab surfaces, winglet surfaces and control surface balance panel cavities must be free of snow, ice and frost.

Question 3

Conditions for take-off with CSFF on upper wing surfaces ?

Answer 3

Takeoff with CSFF on upper wing surfaces is allowed provided all of the following conditions are met:
• The CSFF on the wing tank upper surfaces is only within the lines defining the permissible CSFF area with no snow, ice or frost on the leading edges or control surfaces
• Ambient air temperature is at or above +4°C, +39°F
• There is no precipitation or visible moisture (rain, snow, drizzle, or fog with less than 1 mile visibility)
• Tank fuel temperature is at or above -16°C, +3°F.
