Profile drag on the wings and parasite drag on the body, together with their associated power expenditures, decrease at lower air density.
“whereas profile drag (on the wings) and parasite drag (on the body), together with their associated power expenditures, will concomitantly decrease (Pennycuick, 1975;Norberg, 1990;Rayner, 1990).”

The cost of supporting body weight (induced power requirements) increases at lower air density.
“In particular, the cost of supporting body weight (i.e., the induced power requirements) increase at lower air density, whereas profile drag (on the wings) and parasite drag (on the body), together with their associated power expenditures, will concomitantly decrease (Pennycuick, 1975;Norberg, 1990;Rayner, 1990).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
