Gross Weight?

[t j]

My operating limitations have this statement;

Following satisfactory
completion of the required number of flight hours in the flight test area, the pilot must certify in the records that the aircraft has been shown to comply with § 91.319(b). Compliance with § 91.319(b) must be recorded in the aircraft records with the following, or a similarly worded, statement: “I certify that the prescribed flight test hours have been completed and the aircraft is controllable throughout its normal range of speeds and throughout all maneuvers to be executed, has no hazardous operating characteristics or design features, and is safe for operation. The following aircraft operating data has been demonstrated during the flight testing: speeds Vso ______, Vx ______, and Vy ______,
and the weight ______ and CG location ______ at which they were obtained.”

Some experimentals built in the past do not have this statement in their operating limitations, according to the owners. V speeds are determined at maximum weight, so if you see this in the operating limitations ask the owner for the documentation of it. I put the statement in the aircraft log book.
