  It goes back to Ahlfors that a real algebraic curve admits a real-fibered
morphism to the projective line if and only if the real part of the curve
disconnects its complex part. Inspired by this result, we are interested in
characterising real algebraic varieties of dimension $n$ admitting real-fibered
morphisms to the $n$-dimensional projective space. We present a criterion to
classify real-fibered morphisms that arise as finite surjective linear
projections from an embedded variety which relies on topological linking
numbers. We address special attention to real algebraic surfaces. We classify
all real-fibered morphisms from real del Pezzo surfaces to the projective plane
and determine which such morphisms arise as the composition of a projective
embedding with a linear projection. Furthermore, we give some insights in the
case of real conic bundles.
