Takeoff and Landing Performance Assessment (TALPA) is a method used by airport operators to determine runway conditions for takeoff and landing. It produces a Field Condition report that allows pilots to assess braking action when the runway is not dry.
TALPA assessment generates a Runway Condition Code (RWYCC) ranging from 6 to 0, where 6 indicates a dry runway and 0 signifies nil conditions, meaning braking action is minimal to non-existent.
Separate runway condition codes are published for each third of a runway, and pilots use a Runway Condition Assessment Matrix (RCAM) to calculate their aircraft performance.[1]
TALPA was introduced by the United States Federal Aviation Authority (FAA) in 2016.[1] The TALPA matrix was later superseded by the ICAO Global Reporting Format (GRF), which was based on TALPA and adopted on 4 November 2021.
Runway condition codes
edit| Runway condition code | Landing braking action |
|---|---|
| 6 | Dry |
| 5 | Good |
| 4 | Good to Medium |
| 3 | Medium |
| 2 | Medium to Poor |
| 1 | Poor |
| 0 | Nil |
Methodologies for Performance Assessment
edit- Use of Flight Data Monitoring Systems: Flight data monitoring systems (FDMS) are increasingly being used to assess takeoff and landing performance. These systems collect real-time data from aircraft during operations, allowing for detailed analysis of performance metrics such as speed, thrust settings, and runway conditions. This data can help operators identify trends and improve safety protocols[4]
- Simulation-Based Assessments: Simulation technologies are being utilized to model takeoff and landing scenarios under various conditions, such as different weights, weather influences, and runway surfaces. These simulations allow for comprehensive performance assessments without the risks associated with real-world testing. They can also be used for pilot training to enhance decision-making skills during critical phases of flight[5]
