2. Transport Canada Special Exemption from 602.128(2)(b)

"The purpose of this exemption is to permit pilots-in-command of IFR aircraft operated by holders of an air operator certificate or a temporary private operator certificate to descend below the minimum descent altitude (MDA), when conducting a non-precision approach ... following a stabilized constant descent angle (SCDA) non-precision approach."

EXEMPTION FROM PARAGRAPH 602.128(2)(b) OF THE CANADIAN AVIATION REGULATIONS - Transport Canada

(SCDA is the Canadian term for CDFA).

Peekay, the link says the Transport Canada exemption was over in 2015. I tried to do a search with Transport Canada, to see if it was re issued but came up empty. Do you or anyone else have any further input on exemptions?

thanks,

Hawk
