Within the theoretical framework of a recently introduced approach toapproximate Lie symmetries of differential equations containing small terms,which is consistent with the principles of perturbative analysis, we defineaccordingly approximate Q-conditional symmetries of partial differentialequations. The approach is illustrated by considering the hyperbolic version ofa reaction-diffusion-convection equation. By looking for its first orderapproximate Q-conditional symmetries, we are able to explicitly determine alarge set of non-trivial approximate solutions.
