take-off distance available (TODA) is the full length of the runway plus the length of any clearway. However, if there is no designated clearway, the part of the runway strip between the end of the runway and the runway strip end must be included as part of the TODA.

Note   TODA = TORA + CWY.

take-off run available (TORA) is the full length of the runway available in the relevant take-off direction.

Note 1   TORA = length of RWY.

Note 2   Neither stopway (SWY) nor clearway (CWY) are included in the TORA.
