How should the reported head-wind component be factored into the determination of maximum take-off mass?

Not more than 50 % of the reported head-wind component should be considered.

What percentage of the reported tailwind component must be used when calculating maximum take-off mass?

Not less than 150 % of the reported tailwind component must be used.

Does the runway slope need to be considered in the take-off mass calculation, and if so, in which direction?

Yes, the runway slope in the direction of take-off should be considered.

What runway-related factors, other than slope, are listed as considerations for maximum take-off mass?

The runway surface condition and the type of runway surface, as well as the loss, if any, of runway length due to alignment of the aeroplane prior to take-off, are listed.

Is the ambient temperature at the aerodrome a required input for determining maximum take-off mass?

Yes, the ambient temperature at the aerodrome should be considered.

Which altitude value is specified as a factor for take-off mass determination?

The pressure altitude at the aerodrome is specified.

What is the regulatory reference for the acceptable means of compliance regarding take-off mass for aeroplanes?

AMC1 NCC.POL.125 Take-off -- aeroplanes, under ED Decision 2013/021/R.

AMC1 NCC.POL.125 Take-off -- aeroplanes

Q: What factors should be considered when determining the maximum take-off mass for an aeroplane under AMC1 NCC.POL.125?

The factors are: (a) the pressure altitude at the aerodrome; (b) the ambient temperature at the aerodrome; (c) the runway surface condition and the type of runway surface; (d) the runway slope in the direction of take-off; (e) not more than 50 % of the reported head-wind component or not less than 150 % of the reported tailwind component; and (f) the loss, if any, of runway length due to alignment of the aeroplane prior to take-off.
