AIR BRAKE Interactive Ontario Z-Endorsement Edition (ABI-ONT-Z)

AIR BRAKE Interactive ONTARIO Z-Endorsement Edition

Province of Ontario Air Brake ‘Z’ Endorsement for Drivers

AIR BRAKE Interactive ONTARIO Z-Endorsement Edition (ABI-ONT-Z) is a complete, presentation-ready, air brake instructional resource that fully complies with and supports the Ontario Ministry of Transportation’s Z-Endorsement curriculum. Although structured around MTO’s required curriculum, ABI-ONT-Z contains a substantial amount of important additional detail and material, providing instructors with the most comprehensive and effective teaching tool ever developed for Z-Endorsement air brake training!

ABI-ONT-Z provides a complete, progressive, effective and exceptionally interesting learning experience for your students. The extensive use of multimedia air system and component animations speeds leaning, enhances student retention of critical information and allows the entire ONT-Z program to be presented within MTO’s mandated presentation timelines.

The key to ONT-Z’s exceptional effectiveness is “visual learning”.  Highly detailed technical/mechanical animations and visuals make the normally invisible operation of an air brake system’s components and circuits visible and very easily understood. In short, WE MAKE the invisible VISIBLE! The AIR BRAKE Interactive “visual learning experience” is particularly effective for students for whom English is a 2nd language.
