Governing equations describing the gas and dust production and the accelerating dusty gas flow in a cometary atmosphere are compiled and compared with the information available on the inner coma of the Halley comet. Cometary dusty gas flow calculations, based on the Probstein (1968) approach, yield a first order differential equation for the gas velocity with only one physical solution possible, which is the one of a transonic accelerating gas 'wind'. According to this model, the comet wind starts subsonically at the nucleus, goes through the singular sonic point, and then accelerates further.
