Original Note:
As long as the aircraft is flown at a constant ambient pressure, it will be following the earth's curvature as the altitude is measured from the surface, which is curved, and not a plane. https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/phak/10_phak_ch8.pdf https://calaero.edu/5-types-of-altitude-in-aviation/
