Unfeathering is accomplished by holding the feathering button in the OUT position for about 2s. This creates an artificial underspeed condition at the governor and causes high-pressure oil from the feathering pump to be directed to the rear of the propeller piston. As soon as the piston has moved outward a short distance, the blades will have sufficient angle to start rotation of the engine. When this occurs, the unfeathering switch can be released and the governor will assume control of the propeller. 2, record 2, English, - unfeathering

La régulation automatique du calage s'effectue comme suit : - si la vitesse de rotation diminue et tombe au-dessus du régime pour lequel est réglé le régulateur par la commande d'hélice la vitesse de rotation des masselottes du régulateur décroît et elles tendent à se rapprocher; le ressort [de régulation] se détend et le piston tiroir laisse pénétrer l'huile sous pression dans le cylindre qui se trouve repoussé vers l'avant : le calage des pales diminue. Aussitôt la vitesse de rotation de l'hélice augmente et avec elle la vitesse de rotation du régulateur dont les masselottes tendent à s'écarter sous l'effet de la force centrifuge; le ressort [de régulation] est comprimé et déplace avec lui le piston tiroir qui venant progressivement obturer l'arrivée d'huile diminue le débit de celle-ci jusqu'à ce que soit retrouvé le régime initial pour lequel est réalisé l'équilibre entre la pression de l'huile et la force centrifuge appliquée aux contrepoids des pales. 2, record 5, French, - ressort%20de%20r%C3%A9gulation

The propeller governor incorporates an adjustable stop, which limits the maximum speed at which the engine can run. As soon as the takeoff r. p. m. is reached, the propeller moves off the low-pitch stop. The larger propeller blade angle increases the load on the engine, thus maintaining the prescribed maximum engine speed. 3, record 6, English, - flight%20fine%20pitch%20stop

[The Allison A6441FN-606 and 606A turbopropeller has the two following features :] Mechanical Low-Pitch Stop(MLPS). The mechanical low-pitch stop is designed to prevent the inadvertent entry of the blades into the beta range during flight in the event of propeller-control-system malfunction. The MLPS with a setting of 18. 25 to 18. 5 ° "backs up" the normal hydraulic low-pitch stops. Hydraulic Low-Pitch Stop(HLPS). The hydraulic low-pitch stop is designed to prevent the propeller hydraulic governor from decreasing the blade angle into the beta range during governing operation. The HLPS has a setting of 20 ° blade angle from 30 to 68 ° coordinator. From 68 to 90 ° coordinator HLPS is scheduled from 20 to approximately 31. 5 ° blade angle. This scheduling is called beta follow-up and means that the propeller pitch cannot decrease below 20 or 30 ° during constant-speed operation controlled by the governor. 4, record 6, English, - flight%20fine%20pitch%20stop
