Even though the question does not actually mention it, this question refers to a Class A take-off and in a Class A take-off both the "Go" and "Stop" cases are considered, assuming an engine failure at V_EF and the stop/go scenarios at V₁:

• "Go" distance => TORA and TODA
• "Stop" distance => ASDA

We would calculate the maximum TOM for each of the TORA, TODA and ASDA and choose the most limiting (lowest) mass.

Other factors taken into account to calculate the PLTOM (Performance limited takeoff mass) relate to configuration, such as flap position, runway conditions, and ambient conditions (temperature, winds). For a dry runway, the use of reverse thrust is not considered. For wet runways, where the performance will be severely degraded, the use of reverse thrust is allowed to be considered in the performance calculation.
