'''PSLV - XL:'''

* The PS1 ignites at T+0 providing 4846{{Spaces|1|nbsp}}kN of thrust.
* Within T+1, 4 out of the 6 boosters ignite on ground, each producing 703&nbsp;kN of thrust. 7658{{Spaces|1|nbsp}}kN of total thrust is produced by the combined propulsion of the PSOMs and the PS1.
* At around T+23/26, the remaining 2 unlit boosters are air-lit bringing the rocket at its maximum thrust capacity.
* At T+1:10, the first 4 ground-lit PSOMs have depleted its propellant and now separates and falls down to the  ocean. The remaining 2 PSOMs and the PS1 continue to burn.
* At T+1:35, the remaining 2 PSOMs complete its 70 seconds burn and separate, leaving the rocket in a Core Alone configuration.
* At T+1:50, the PS1 has completed its 110-second burn and it separates and the [[Vikas (rocket engine)|Vikas Engine]] inside the PS2 ignites.
* The second stage burns for around 130 seconds and around T+4 minutes, the second stages shuts off and separates.
* The third stage, which is a solid rocket booster, and burns 80 seconds and then coasts for the remainder of time and around T+8/10 minutes, it separates and the 4th stage ignites to give the rocket a final push into the orbit.
* This 4th stage burn is highly variable and depends on the mass and number of payloads and usually is around 500 seconds long. The 4th stage may shut off around T+16/18 minutes followed by the '''Payload Deployment'''.
