I have been reading about Canada requiring a 406 ELT on all aircraft operating in Canada on February 1, 2009. This includes USA registered aircraft.
I contacted Transport Canada and the reply I received is below. It certainly is nice to actually get direct correspondence from the regulatory agents themselves.
Thank you for your question regarding the requirements of a 406MHz ELT in Canada.
You asked whether Automatic portable ELT's conform to the Transport Canada regulations. The proposed regulation which we anticipate will come into effect on February 1, 2009 requires the carriage of a 406 MHz ELT or an alternate system that has the same performance as a 406MHz ELT. Similar to the 406MHz ELT the alternate means must also be capable of providing immediate notification of an aircraft incident without activation by a crew member. In this context PLB will not by themselves be considered as meeting the requirements of the proposed regulation. However, a PLB could be used as an additional device to provide location information of an aircraft incident.
I would also like to add that Transport Canada will be offering an exemption to provide a two year transition period to allow all aircraft flying in southern Canada including foreign registered aircraft, to meet the requirements of the regulation. During this transition period such aircraft will be required to carry a 121.5MHz ELT. The transition will not apply to new aircraft, the purchase of a used aircraft or aircraft flying into northern Canada (north of 55 Lat west of 80 Longitude and 50 deg. east of 80 Longitude ) as these situations will require a 406MHz ELT as of February 1, 2009.
