- rockostrich 3y agoDo you mean landing with a tailwind? A headwind should allow the plane to create the same amount of lift it needs to avoid stalling at lower ground speeds.
- Toutouxc 3y agoYes, that’s correct, but the headwind stops being so headwind-y near the ground, so your plane needs to go a bit faster to compensate for the loss of headwind-ness in the seconds before touchdown.
- The5thElephant 3y agoOn the flip side you also get ground-effect when you are low to the ground where the high-pressure underneath the wing gets trapped against the ground creating a cushion of pressure increasing lift.
