At this point, the pilots will contact ATC for push and start clearance , allowing the plane to be pushed back from its parking position (if applicable, depending on the airport) and to start its engines in sequence. After reaching 100 knots, the aircraft will continue to accelerate to what is referred to as its V1 speed.
