The 3rd generation quarks are, due to their large mass, highly sensitive probes for new physics connected to the electroweak symmetry breaking. Linear e$^+$e$^-$ colliders allow for clean measurements of heavy quark final states between the $Z$-Pole and the TeV scale with sensitivities to different aspects of the manifestations of new physics in the extracted electroweak couplings. At the same time these processes are ideal benchmarks for the optimization of detectors at linear colliders. This includes for example the event-by-event distinction between $b$ and anti-$b$ quarks indispensable for the proper measurement of differential observables. The contribution will outline with full simulation studies the capabilities of the ILD concept. An efficiency of 30\% has been achieved for the charge measurements in $b\bar{b}$ final states, which is about a factor three better than that presented earlier. We will also present new results using the fully hadronic $t\bar{t}$ final state. Finally quantitative estimations of the reach in detecting the onset of new physics will be given.
