TODA is TORA plus clearway (if there
is any)
ASDA is TORA plus stopway
(if there is any)
So to answer the question, stopway is not included in TODA.
A stopway
must be the same width as the runway and of sufficient load bearing strength to
support the a/c in the event of a rejected take-off and clear of any non
frangible obstacles.
A clearway is an invisible path/plane
at the end of TORA of maximum semi-width of 75m with a maximum upward slope of
1.25% and clear of any non-frangible obstacles. The maximum length of the
clearway that can be utilised is limited to 50% of
TORA which makes the maximum length of TODA a 150% of TORA.
