Abstract
L'invention concerne un circuit d'avertissement de distance au sol. Elle se rapporte à un circuit qui transmet un signal vocal d'avertissement lorsque l'aéronef est trop près du sol et va trop vite, n'a pas sorti son train d'atterrissage ou n'a pas abaissé ses ailerons. Application aux circuits d'avertissement du pilote d'un aéronef.
