A rejected takeoff occurs when an aircraft begins its takeoff roll but must abort the attempt. There are many reasons for a rejected takeoff occurrence including mechanical problems, objects obstructing the runway, and more. These situations demand precise decision-making, especially when other aircraft are present or speeds approach Rotational Velocity.
The Aireon Safety Dashboard supports and enhances air navigation service providers’ (ANSP) safety assurance programs by identifying leading indicators of the industry’s biggest operational risks. To aid aviation professionals in detecting and addressing a rejected takeoff, Aireon’s Safety Dashboard has introduced a new metric on the platform.
The new metric identifies these incidents by detecting when an aircraft’s speed exceeds 60 knots on the runway without achieving flight. This data is crucial for understanding the circumstances surrounding a rejected takeoff, as it offers insights into the pilot’s decision and the safety of the operation.
Key metrics for analysis include:
- Maximum Speed at Rejection Point: Capturing the top speed reached before the takeoff is rejected provides valuable information about how close the aircraft was to a successful takeoff.
- Runway Remaining at Rejection Point: Understanding the distance left on the runway at the point of rejection can help assess whether the aircraft had enough space to decelerate safely.
- Runway Remaining When Aircraft Decelerates to 50 Knots: This measurement provides insight into how effectively the aircraft was able to slow down after the rejected takeoff.
By closely analyzing these metrics, aviation professionals can better understand and improve decision-making processes during these critical moments, ultimately enhancing safety and operational efficiency in the skies.
