I can't rememner off hand the T2-T3 MCT but this tool will tell you if you are OK if you enter your arriving and departing flight

But VS wouldn't have sold the ticket if it didn't meet the MCT or are prepared to take the risk of having to rebooking you if your flybe flight is delayed.
But remember that every day of the year tends of thousands of people do meet the MCT times otherwise they would increase them!.
