Description

Runway surface condition assessment training plays a vital role in safe airport operations. This course gives aviation professionals clear, practical methods to evaluate runway surfaces in all weather conditions. Participants learn how to identify common contaminants and understand how each one affects aircraft performance and runway usability.

The training begins with an introduction to the Global Reporting Format (GRF). Instructors explain why the industry uses GRF as a unified standard. Learners study different types of contaminants, such as water, snow, slush, ice, and wet surfaces. They also explore how these conditions influence braking action, stopping distance, and overall runway safety.

Applying the RCAM and RwyCC

A core part of the program focuses on the Runway Condition Assessment Matrix (RCAM). Instructors show how to use RCAM to assign the correct Runway Condition Code (RwyCC). Participants review pilot braking action reports, friction measurement values, and contaminant depth. They practice combining these data points to make quick and accurate assessments. The course also addresses the limits of friction testing and explains when friction readings should or should not guide decision making.

Practical Case Studies and Real Scenarios

Practical application is at the center of the course. Learners work through real case studies that show how runway conditions affect takeoff and landing performance. They analyze events from winter operations, heavy rain, and rapid temperature changes. Through these examples, they gain a clearer picture of how runway conditions evolve during daily operations.

SNOWTAM Reporting Skills

The program also trains participants to create accurate SNOWTAMs. Instructors guide them through the full reporting process, from surface inspection to final communication with air traffic services and flight crews. Each trainee practices writing sample SNOWTAMs to build confidence and speed.

Regulatory compliance supports every part of the training. The course references ICAO Annex 14 and related guidelines. Participants learn how to apply these requirements in real time and maintain a consistent reporting standard.

By the end of the runway surface condition assessment training, participants can perform reliable runway inspections, report conditions clearly, and support safe aircraft operations in all seasons.
