minus-squareoffbyone@feddit.uklinkfedilinkEnglisharrow-up29·1 year agoYes, less air means less lift. Same issue with altitude.
minus-squareInverseParallax@lemmy.worldlinkfedilinkEnglisharrow-up5·1 year agoIt also means less air, as in density, so the fans and compressors are able to pull in less air to burn with. The fadecs compensate for this automatically but it means the output is derated till you get far enough off the ground to get speed.
