Q:  I'm confused.  Is this a gross weight increase, a ramp weight increase, a useful load increase, or a payload increase?

A:  Yes, this is a little confusing.  Actually, the STC allows all four.

Since it does not increase the empty weight of your airplane (OK, less a few ounces for the required STC paperwork!), your max gross takeoff weight is increased by 150 pounds.  If your airplane is a 1978 - 1980 182Q model, this represents an increase in useful load of 150 pounds as well.  Your original ramp weight was 2960 before we increased it to 3110.

Should yours be a 1972 - 1976 182P or a 1977 182Q, your ramp weight was less... it has now gone from 2950 to 3110;  your useful load has therefore increased by 160 pounds.

Payload is another matter entirely.  Fuel is not considered payload, but is a portion of your useful load.  So, for example, if you elect to use only 60 pounds of the 150 pound MGTOW increase for fuel (about 10 gallons), your payload increase is 90 pounds.  If no portion of the increase is used for fuel, both your useful load and payload have increased by 150 - 160 pounds.
