B73 Minimum rwy length for T.O

[Manicured garden]

Hey guys!
Just a question I faced recently;before TO, we look for the CSPD or use Strong-Pilot for TO Speeds depending on weight/temperature etc.

But how can we calculate the minimum rwy length we need for the specific conditions? Is there any simple way?
every company has its own SOP -including minimum rwy length for operation but if we would like to find out the minimum rwy we need for departure, what would be the formula?

Thanks in advance.

You calculate it using the runway TO performance tool your company uses which should tell you the TDR.
If your using charts then it won't, but i can guarantee that your TDR will be less than TDA.

have a look at your fcom (performance dispatch ) and look for TORR.
Dont forget to add line up distance required/used.
