Rocket flight procedure implementation

[Vie0n]

• Takeoff detection #80
  Detect when the rocket has successfully taken off by using the onboard accelerometer
• Emergency engine shutdown
  Detect if the rocket has treaded off course by using the gyro or accelerometer
• Engine ignition (after a 4s delay)
  Start a four second timer, and if no issues are detected (checklist item 2), ignite the engines
• Rocket apogee detection and parachute deployment
  After a successful launch, await the descent (fall) and deploy the onboard parachute by using the accelerometer

Note: Every check requires at least three subchecks (using three different sensors to ensure correct measurements and error reduction)
