Runway condition for takeoff performance is determined with contaminants type and depth for contaminated runway takeoff (not braking action only).
And the braking action column shown in Matrix must be used for downgrade purpose only.
In case of slush 3mm runway condition, it may be considered braking action Good(Wet).
But the reported braking action is Medium.
In this case, which runway condition do you select for takeoff performance calculation, Good(Wet) or Medium(such as dry snow 3mm)?
If you select braking action Medium(or dry snow 3mm), it may be considered conservative.
For application of crosswind limitation.
Which crosswind limitation do you apply, Good or Medium?
