There are two cases:
First line "With clearway" - if your MTOW for DRY was calculated using RTOW and clearway was used for calculation. Second, "Without clearway" have to be used if MTOW was calculated using RTOW for runway without clearway or MTOW was calculated by QRT. By the way, no more FCOM 2.04.10 exists because new FCOM format - refer to PER-TOF-CTA chapter.
