6 month to 2 years terminal 2-4 years enroute just depends on facility and your ability.These are great and clear up a lot of my questions. One more that I didn't seem to find an answer about (maybe I'm looking in the wrong place} is how long does it typically take to certify and reach the CPC band? Terminal vs en route? I feel like I remember seeing in some forum here that it varies and there was no definite answer but I can't remember for certain and can't find it again.
