Abstract
LA PRESENTE INVENTION EST RELATIVE A UN NOUVEAU SYSTEME D'AVERTISSEMENT DE VITESSE DE DESCENTE EXCESSIVE, NOTAMMENT POUR AERONEFS. CE SYSTEME EST CARACTERISE EN CE QU'IL COMPREND DES MOYENS DESTINES A MESURER L'ALTITUDE DE L'AERONEF ET A PRODUIRE UN SIGNAL D'ALTITUDE CORRESPONDANT; DES MOYENS DESTINES A DIFFERENCIER LE SIGNAL D'ALTITUDE ET A PRODUIRE UN SIGNAL DE VITESSE DE DESCENTE CORRESPONDANT AU SIGNAL DE VITESSE DE CHANGEMENT D'ALTITUDE; DES MOYENS COMPARATEURS DESTINES A COMPARER LES SIGNAUX D'ALTITUDE ET DE VITESSE DE DESCENTE ET A PRODUIRE UN SIGNAL D'AVERTISSEMENT LORSQUE LA VITESSE DE DESCENTE DEPASSE LA VITESSE MAXIMUM POUR L'ALTITUDE RESPECTIVE SELON UNE RELATION PREDETERMINEE. UTILISATION POUR AERONEFS ET NOTAMMENT DE TYPE HELICOPTERE.
