Yes, Kevin Hawley mentioned that the Flight Manual supplement is misleading - that's probably what he's referring to.

You'd have to read the STC and see if the M20S specifically mentions a gross weight increase. It would have to increase an Eagle from 3200 and an Eagle 2 from 3300. Mooney bought the STC from Bob Minnis (Minnis Aviation LLC). Who knows? Minnis may have just assumed that the R and the S had the same Max Gross Weight. I definitely don't have a dog in this fight, but was just passing the recent FB post along to the seller that now would be the time to verify this with Mooney so that the buyer doesn't come back and cry misrepresentation later. That can get expensive.

Why "Whoops"? So let's just read the STC....

If you read the STC it says "3. The modified aircraft shall be operated in accordance with Minnis Aviation report M1029-12 Airplane Flight Manual Supplement, Revision C, dated 04/17/13 or Mooney International Corp document SUPP0029 Airplane Flight  Manual Supplement (AFMS), Revision D dated 11/14/17 or later FAA approved revision"

The STC is the legal primary governing document.  The AFMS is supporting the STC.  In this case the STC defers to the AFMS to specify and govern the operating limitations.  The AFMS, as pointed out, clearly says "3,368 Lbs." for any R or S. with the STC.  

I don't understand the confusion.  Both the STC and supporting AFMS have been approved by the FAA. It is 3,368 Lbs. for the M20S.

It seems crystal clear.  It makes me wonder why people at Mooney Corp are so confused.

That’s why I said “Whoops”

I bet you're a hoot at parties.  

You aren't completely wrong though.  Those numbers vary quite a lot with conditions, altitude, etc... obviously.  I wasn't trying to say every time you take the aircraft up that you're going to get the exact same performance.  Sometimes it's 172kts... sometimes it's 177kts.  Sometimes it's 12.2gph... sometimes it's 13.3gph.  For example, here is a photo of 175kts on 12gph @ 10.5k feet.  (note, this is before we removed the Moritz gauges)

Does this show a 37kt tailwind?

The wind is 37kts. The tailwind component is closer to 25kts based on the difference between TAS and grounds speed.  Either way, a nice push!
