Mandatory ACAS/TCAS – Are You Ready?
Airborne Collision Avoidance Systems (ACAS) and Terrain Collision Avoidance Systems (TCAS) are by no means new to our discussions. The systems have been in wide use and acceptance for many years. In point of fact, Canada is well behind the rest of the world in the mandated use of such equipment. On July 1st of this year the use of ACAS/TCAS will become a mandatory item on commercial aircraft that previously did not require such.

This change has been under active discussion since at least 2000. The CAR’s were amended to include an ACAS rule in July of 2007 giving operators up to 2 years to comply on older aircraft. That compliance date expires this July 1st. For those operators hoping for a reprieve or last minute exemption, the simple fact is that July 1st is now the date and after that, you will be required to have the appropriate ACAS/TCAS modifications installed, approved and functional on your aircraft.

WAAS 101
One of the more popular acronyms in our industry today is WAAS - Wide Area Augmentation System. This term relates to a space-based (GPS) augmentation system aid that has been developed to augment the accuracy of GPS in an aircraft and much more.

WAAS improves accuracy, integrity, and availability of the GPS signals. It provides correctedGPS signal data that reduces errors which may be caused by temperature, baro mis-set effects, ionospheric conditions, solar activity or atmospheric conditions.
