We evaluate the discovery reach of the ATLAS experiment for down type isosinglet quarks, D, using both their neutral and charged decay channels, namely the process pp→DD̄+X with subsequent decays resulting in 2ℓ+2j+≠E T , 3ℓ+2j+≠E T and 2ℓ+4j final states. The integrated luminosity required for observation of a heavy quark is estimated for a mass range between 600 and 1000 GeV using the combination of results from different search channels.
