V Speeds

Na aviação, V-speeds são termos padrão utilizados para definir velocidades importantes ou úteis para a operação de todas as aeronaves, incluindo aviões de asa fixa, planadores, autogiros, helicópteros e dirigíveis. Essas velocidades são obtidas a partir de dados obtidos por designers e fabricantes de aeronaves durante os testes de voo e verificados na maioria dos países por inspetores do governo durante vôo de aeronaves de testes de certificação de tipo. Usá-los é considerada uma das melhores práticas para maximizar a segurança da aviação, a performance da aeronave, ou ambos.
