A basic flight instrument to provide the pilot the means, by which, he can easily remain upright during instrument conditions. This flight instrument will be highly trustworthy, in that it will be absolutely tumble free due to its basic input derivatives. The instrument will be provided with two separate erection systems, whereby, the roll erection system will consist of a gimbal cage, spring tension erected and the pitch erection system will consist of a drum, the rotation of which will be properly erected by means of a gravitational weight and rotational reversing system. 1, record 1, English, - roll%20erection%20system

During the first phase of rapid align, the liquid level signal controls the platform pitch erection. However... to avoid a large vertical error when the control of the platform pitch gimbal switches to the pitch pick-off in the second phase of rapid alignment, a phase reversal is required. The phase reversal is designed to keep all of the signal phasing correct while reversing the phase of the gyro pick-off signal. If the phase of the gyro pick-off were not reversed, the combined signals could null with a non-level gimbal and a non-vertical gyro spin axis. With the pick-off reversal, the same type of cancellation occurs but the gyro spin axis is vertical. 1, record 3, English, - gyro%20pick%2Doff%20signal

Durant la première phase de l'alignement rapide, le signal du niveau à liquide commande l'érection en tangage de la plate-forme. Cependant, il est nécessaire d'inverser la phase afin d'éviter un signal important d'erreur de verticale lorsque la commande du cardan de tangage de la plate-forme est donnée au détecteur de tangage durant la deuxième phase de l'alignement rapide. Cette inversion de phase est conçue pour garder la mise en phase correcte du signal lorsque la phase du signal détecteur du gyroscope est renversée. Si la phase du signal détecteur du gyroscope n'était pas inversée, les signaux composés pourraient devenir nuls avec un cardan qui ne serait pas correctement en érection et un axe de rotation qui ne serait pas à la verticale. En effectuant l'inversion du signal détecteur, le même genre d'annulation se produit mais l'axe de rotation du gyroscope est à la verticale. 1, record 3, French, - signal%20d%C3%A9tecteur%20du%20gyroscope
