Book excerpt: Task 2 of the All-Weather Landing Systems project is concerned with piloted flight simulation tests of various techniques designed to aid the pilot to detect and cope with low-level wind shear on approach and landing. This report documents the tests of Phase 2, a comparative evaluation of the most promising panel-displayed techniques from the Phase 1 study. The operational situation of a DC-10 aircraft landing in Category I visibility with ILS guidance was simulated. Winds corresponding to inversion-layer, frontal, thunderstorm and 'no-shear' conditions were simulated to provide test profiles. The 'baseline' aiding concept was the conventional DC-10 manual approach management. The aiding concepts tested were based on ground speed displays (first experiment), flight path angle (second), and modified (acceleration-augmented) flight director (third experiment). The results showed that ground speed displayed on the airspeed indicator and the modified flight director can improve performance significantly over baseline, especially on the thunderstorm wind profiles, which was the most difficult condition.
