Narrative:
On visual approach at approximately 1;000 ft AGL we received an anti-skid right fail level 2 alert. We decided to do a go-around to troubleshoot the problem. After running the checklist to completion we requested fdp for runway xx. We were dispatched with an MEL for the #3 thrust reverser inoperative (along with a fuel pump and several other items). Additionally; the runway was reporting condition codes of 5/5/6. When I asked for the fdp for the runway being used along with the non-normal selection for no thrust reverser as well as no anti-skid braking and those condition codes; we received an error from aerodata because it couldn't calculate the performance with those performance penalties. The landing distance chart in the anti-skid right fail checklist assumes that all the thrust reversers are operative. We could not find a chart that gave us landing data for both anti-skid inop and #3 TR inop. We did our best interpolation between the charts we did have and got 6929 ft required on the 10;000 ft runway.

Title: MD-11 First Officer reported a go around receiving an Anti-Skid R Fail Level 2 Alert.
Narrative: On visual approach at approximately 1;000 ft AGL we received an Anti-Skid R Fail Level 2 Alert. We decided to do a Go-Around to troubleshoot the problem. After running the checklist to completion we requested FDP for Runway XX. We were dispatched with an MEL for the #3 Thrust Reverser INOP (along with a Fuel Pump and several other items). Additionally; the runway was reporting condition codes of 5/5/6. When I asked for the FDP for the runway being used along with the non-normal selection for no thrust reverser as well as no anti-skid braking AND those condition codes; we received an error from aerodata because it couldn't calculate the performance with those performance penalties. The landing distance chart in the Anti-Skid R Fail checklist assumes that all the Thrust Reversers are operative. We could not find a chart that gave us landing data for both anti-skid inop AND #3 TR inop. We did our best interpolation between the charts we did have and got 6929 ft required on the 10;000 ft runway.
