Morphology

glide + slope

The phrase combines 'glide' (to move smoothly through the air) with 'slope' (a slanting surface/path), so an average B1 learner can infer it refers to a sloping path used while gliding — i.e., the aircraft's descent path. Although in aviation it has a specific technical sense (instrument guidance), the core idea of a downward/angled flight path is directly derivable from the constituents.

Etymology

The noun glide slope shows a smooth, sloping path down to the runway: glide means to move smoothly and slope is a downward line. Aircraft follow this guided, gentle descent, so the phrase means the 'downward flight path' pilots use to land.
