Thank you for your reply,
I was thinking the same thing, but if you have enough power to comply with the second segment, shouldn’t this power be sufficient to comply with the first?
Do you think that has something about having hazards/damage to the aircraft if the failure occurs before TDP/DPATO?
Sorry, I have a glitch and cannot see your reply unless I make this reply!
To answer the first point, the drag is much higher in the first segment, as you are at a much lower speed and also the gear is down (I think the gear alone is worth a 50 ft/min penalty), so even though you have more power, the overall effect is that the RTOM is limited by the performance in that segment with lower Vtoss values. From memory, the demarcation point is Vtoss = 60 kias, when the second segment becomes limiting - which is logical because the Vtoss airspeed is closer to Vy.
I don't believe your second point is a factor - the rejected take off will never limit the RTOM in a runway take off profile (it will do in a helipad profile though).
