There appear to be quite bit variation in the FW pitot systems, as an example the V34 had meter correction around 13km/h at 550km/h (that includes compressibility because the correction seem to be calculated in the different order than current IAS/CAS/TAS system).

That's because of changes to the airspeed measurement systems used Gripen.

There is allways some error in pitot tube and metering systems, that is why position error is measured generally allways for performance tests. Therefore using position error of a plane with another plane is not relevant.

It is when the planes use the same system but different locations of the point of measure.

The location does not matter, there is allways variation even among similar installations. That is why calibration flights are made in the beginning of the performance tests.

Hm... That is a good example how a quote is taken out of context.

"The location does not matter, there is allways variation even among similar installations."

What ever is the location of the pitot tube, the position error should be measured in that particular plane. The correction of another plane with similar installation is probably more or less different.

Wasn't taken out of context Gripen.  The measuring system is not in the same location in the FW-190A8 and above.

Actually it was taken out of context; it does not matter what ever is the location pitot tube, the error of that particular installation should be measured. It does  not matter what plane, sub type or installation we talk about, the error should be measured.

Well, anybody can read from above who actually has problems to understand the speed merasurements and corrections.

Not really Gripen.

Anyone can read you have an obvious agenda.
