For the Weight & Balance UI, download c90_plugins-main. Exercise at 1900 rpm * Engine • The governor moves oil to and from the propeller hub in front of the piston • As oil is moved into the hub, the piston is forced rearward, and blade angle increases •As oil is moved out of the hub, the piston moves forward, and blade angle decreases • When the engine is off, oil pressure decreases in the hub and the blades remain at minimum pitch Propeller blade rotates around So not only does the oil pump inside the propeller governor keep turning at high speed and hence providing normal propeller oil pressure, but also this pump keeps getting fed new oil supplied by the oil pressure pump in the accessory gearbox. This week I flew with an owner-pilot of a beautiful, late-model King Air 300, doing a bit of in-aircraft recurrent training. 2. The prop lever controls oil going into the feathering mechanism to change the Most people would immediately suspect a problem with the FCU, or maybe a P3 problem (bleed air going into the FCU) or possibly a P y problem (air going from the FCU to the prop governor). That will reduce the power to the prop and slow it down, even if both the primary and the overspeed prop governor are failed or the prop blades are stuck at a low On the other hand, most light piston twins will be in an underspeeding – “Off of the governor” – condition somewhere on the base or final leg and at that time the prop levers may be placed fully forward with no noticeable change in RPM or noise taking place. Q-Chat. Account (0) Account (0) 1-888-954-6424. I saw in the records that this King Air had its prop and overspeed governors overhauled in 2013. But experience has taught me not to dig into the FCU without first going “upstream” to the oil-to-fuel A NORMAL King Air landing is most commonly done with the prop levers remaining in the cruise setting until the propeller speed decreases comes off of the governor. A common misconception is that the engine oil pressure pump will not be rotating fast enough, with a shutdown super king air 200/b200 pilot training manual. 06).
