What is crucial to monitor during the transition to assigned altitudes to avoid deviations?

Monitoring altitude is crucial during the transition to assigned altitudes to ensure that the aircraft maintains its intended flight path. Deviations in altitude can lead to potential safety hazards, such as altitude busts, which occur when an aircraft climbs or descends outside of assigned altitude parameters. This monitoring is particularly important during critical phases of flight, like climbing or descending, where precise altitude adherence is essential for safe separation from other aircraft and for compliance with air traffic control instructions.

Maintaining the correct altitude contributes to the overall safety of the flight and ensures adherence to regulations. By keeping a close watch on altitude during transitions, pilots can react promptly to any changes or discrepancies that might develop, thereby minimizing the risk of incidents.
