Hi,
The term relevant is usually type specific and can be found in the a/c Part B.
Relevant= The runway used before the aircraft is below 60 knots.
Further the company SOP is as follows:
Runway length:
3000m and above= Only take touchdown zone as limiting
3000m-1500m= Touchdown and mid-point
1500m and less= Obviously you take all three.
Like I said this can be type/ company specific though.
Hope this helps
baby.
