The method of approximate lambda operators leads to a new generation of highly sophisticated stellar non-LTE model atmospheres. Up to now little was known about the influence of line blanketing in such models. With this paper the author begins the systematical investigations of line blanketing effects. As a first step, he presents results of non-LTE model atmosphere calculations for hot stars (60,000K ≤ Teff ≤ 100,000K), such as subluminous O stars and central stars of planetary nebulae, that include very detailed model atoms for hydrogen, helium and carbon. Altogether, up to 35 non-LTE levels and 94 line transitions have been fully consistently incorporated.
