Narrative:
While conducting the preflight at cmh; I requested takeoff data for runway 28L at intersection C2. Sabre came back with:uplink failurefms error : scap calculation error.runway/intr not foundi found it odd since taxiway C2 is the first intersection after the full length of 28L. I then requested the takeoff data for the full length of 28L and got this back from sabre:takeoff data** part 01 of 01 **************************T/O cmh 28l10113 FT737 CFM56-7BXX************************[...]************************partial runway CODES28L/F 8738FT 28la28l/C1 8288FT 28LB************************** end of part 01 **the data does show the correct runway length for 28L (10;113 ft) near the top. However the partial runway intersection codes are in error. Taxiway F does not intersect with runway 28L at all. Taxiway C1 is at the approach end of 28L and is the taxiway used for a full length takeoff and should not indicate 8288 ft remaining. Granted the intersection codes are not used on the 737; but the data they display is in error. This may also be a concern for the [other aircraft in the] fleet.I queried the ground controller to see if the taxiway designations had changed and he said they had not in the two years he had been there. We departed full length but we would not have been able to get data for an intersection C2 departure should we have needed it.
