Narrative:

We have been told that shortened runways (such as 9R at gru) are taken into consideration in the runway data when received via ACARS. There is also a NOTAM stating this. However; there is no way for the pilots to know positively that the correction to runway length has been taken into account. The runway data should indicate that the runway length has been taken into account. It is very wrong not to have this information on the ACARS runway data printout. I have seen runways in south america displace over 4;000 meters. Runway length is critical; especially when wet as in today's flight. We need to know that the numbers are based on a limitation; just as ACARS provides MEL restrictions on a runway data printout.

Title: A pilot reported that pre-takeoff performance data for SGBR's shortened Runway 9R did not specifically state that the construction runway length was taken into account.
