launch sequence
Ignition startup protocol
A launch sequence is the ordered series of steps and procedures carried out before launching a rocket, spacecraft, or missile.
Each step must be completed and verified before proceeding to the next, culminating in ignition and liftoff.
The term extends to any methodical startup procedure: The pilot ran through the launch sequence before takeoff.
In figurative use, it can describe any deliberate preparation leading to a significant event or action.
