Block Speed

What does Block Speed mean in aviation?

Measuring Aircraft Efficiency

Block Speed measures the average speed of an aircraft from gate to gate.

Block speed is the average speed of an aircraft from the time it leaves the departure gate to the time it arrives at the arrival gate. It includes taxiing time and in-flight time.

• Operational and Scheduling Relevance: This measurement is important for airline scheduling and efficiency analysis.
• Factors Affecting Block Speed: Air traffic control, weather conditions, and airport congestion can influence block speed.
• Different from Airspeed: It is different from airspeed, which is the speed relative to the surrounding air during flight.

Block speed is a comprehensive metric in aviation, reflecting the overall average speed of an aircraft throughout its journey, including ground and air segments.
