TAWS Regulations now in effect!

TAWS Rules

Transport Canada issued the final amendments to the CARs mandating which aircraft require a Terrain Awareness Warning System (TAWS) on July 4th.  Aircraft manufactured before July 4, 2012 have two years after the date of the final rule to have a TSO-C151b-compliant TAWS Systems installed and Transport Canada- certified.

The Transport Canada TAWS regulations also require that the TAWS equipment incorporate a unique Canadian requirement for Enhanced Altitude Accuracy (EAA) functionality.  All TAWS Systems must address the EAA requirement within 5 years of the date of the rule’s promulgation.

The Definition of TAWS:

Terrain Awareness Warning System which is an aircraft system that is intended to provide the flight crew with both aural and visual alerts to aid in preventing inadvertent controlled flight into terrain, obstacles or water.

TAWS Class B

The Class B system provides a good level of protection at a reasonable cost and it will be required for Private turbine-powered Aeroplanes configured with 6 or more seats, excluding pilot seats, commercial subpart 703 air taxi Aeroplanes configures with 6 or more seats excluding pilot seats and Commuter subpart 704 Aeroplanes configured with 6 to 9 passenger seats excluding pilot seats.

TAWS Class A

The Class A system provides the highest level of protection but it has a significantly higher cost than a Class B system.  It will be required in commuter subpart 704 Aeroplanes configured with 10 or more passenger seats, excluding pilot seats and in aeroplanes operating under subpart 705 airline operations.
