| Nov 8, 2022 at 19:16 | comment | added | sophit | Mmh, I'm not that sure that lower swept angle and/or higher aspect ratio are mainly due to a switch toward supercritical airfoils. For a jetliner, OEI climb at takeoff normally drives the choice of the AR, while CG location, weight and pitch and lateral stability drive the choice of the sweep angle. | |

Anyone who clicks the link can read through the Q, the As, and comments to see how you got to this one if they're interested. | |

retag; note: airliner already encompasses boeings and airbuses

(also that's one of my all-time favorite answers on this site). So, in case you're interested in the whole wing, feel free to edit the question. | |

| Apr 18, 2022 at 20:55 | comment | added | John K | I can't provide any data, but my understanding is the main effort has been to improve stall behaviour. SC airfoils suffered from laminar bubbles at the LE with LE initiated flow separation at stall = holy cow when it goes. This is why some airplanes like the CRJs have stick pushers. Newer designs have tamed that behaviour somewhat. | |
