Aircraft Ground Deicing Training Courses
De/Anti-Icing training course covering all qualification levels from DI-L10 to DI-L140
Conformant with the latest and recently updated requirements of SAE International AS6285 & AS6286
Overview
Winter operations are among the most safety-critical activities in aviation. A single training or qualification gap can lead to aircraft delays, operational disruption, regulatory non-compliance, and increased safety risk.
Our aircraft de-icing and anti-icing training courses combine in-depth theoretical knowledge with practical, hands-on instruction, helping aviation organisations maintain safe, efficient, and compliant winter operations. Training is available for de-icing vehicle operators, flight crew, supervisors, instructors, quality and compliance personnel, and management teams.
In line with the publication of SAE International AS6286 Revision E in May 2026, our training programmes have been updated to incorporate all new and revised qualification requirements. This ensures participants receive training that meets the latest industry standards and best practices for aircraft de-icing and anti-icing operations.
All courses are fully compliant with SAE International AS6286 and cover qualification levels from DI-L10 through to DI-L140, supporting both initial qualification and recurrent training requirements.
Whether you require aircraft de-icing certification, anti-icing training, instructor qualification, recurrent competency training, or management-level winter operations awareness, our programmes provide the knowledge, skills, and regulatory compliance needed to keep your operation winter-ready.
