Prima facie, the AirIndia Express incident is intriguing. The aircraft on the left is the one involved in the incident of contact with obstacle after takeoff. Both aircraft have the similar acceleration to 130kts. They cover roughly the same distance. Their mass may vary but for the same ground speed, the distance seems to be the same. Passing 130kts, the aircraft's acceleration seems to have slowed down considerably to reach 150 kts . 76kt - 135 kt 3395' covered 135kt- 150kt 3049' covered Acceleration rate dropped by a substantial 62% after passing 125 kts G/S. The aircraft climbed at normal ROC to reach cruising altitude as the other aircraft.
