(b) A threshold needs not to be provided on a [take-off runway](https://avioverse.aero/glossary/easa/take-off-runway).

(c) A threshold should be located at the extremity of a runway unless operational considerations justify the choice of another location.

(d) When it is necessary to displace a threshold, either permanently or temporarily, from its normal location, account should be taken of the various factors which may have a bearing on the location of the threshold.

(e) When the threshold is displaced, the threshold location should be measured at the inner edge of the threshold [marking](https://avioverse.aero/glossary/easa/marking) (the transverse stripe across the runway).
