A new method of calculating model atmospheres for hot stars subject to constraints of radiative, hydrostatic and statistical equilibrium is introduced using approximate lambda operators, and the exact solution of the transfer problem is obtained by combination with a perturbation technique. Model atmospheres with up to 100 atomic levels in non-LTE can be constructed, exceeding remarkably the capacities of the classical linearization approach as presented by Auer and Mihalas (1969). It is now possible to examine the effects of metal line blanketing in non-LTE stellar atmospheres, since many more sources of opacities may be included. The applicability of this method is demonstrated by calculating a small sample of pure-hydrogen atmospheres.
