Usage examples

Tüüri äärmises asendis hoidmine on õhutakistus (lennuki asend õhu suhtes on nina üleval) ning vajatakse suuremat tõstejõudu ja suuremat kohtumisnurka, mille tulemusena takistus on suurem ja varisemiskiirus suurem.

angle of attack

Usage examples

In order to not lose altitude, the pilot must increase the wing’s angle of attack (AOA) to ensure that the vertical component of lift is sufficient to maintain altitude.

AOA abbreviation

Usage examples

As the AOA increases, lift as well as drag increases; however, above a wing’s critical AOA, the flow of air separates from the upper surface and backfills, burbles and eddies, which reduces lift and increases drag. This condition is a stall, which can lead to loss of control if the AOA is not reduced.
