Abstract: We report on our preliminary determination of the atmospheric He abundance pattern in hot subdwarf stars on the basis of a highly homogeneous approach using a large sample of spectra. Our survey covers the domain 4.5 ≤ log g ≤ 6.5, 20,000 ≤ Teff ≤ 75,000 K, and –6 ≤ log He/H ≤ +4. That pattern is both complex and fascinating.
