Kinda hard to feather the prop on a piston single.
Bob Gardner "Seth Masia" wrote in message ... I agree. It also looks to me as if the prop is feathered. Other issue is that the direct route Rock Springs to Leadville is via Tennessee Pass, which is also about 400' lower. Crossing Vail Pass means you still have to cross Fremont Pass, about 900' higher than Tennessee. Seth "ET" wrote in message ...

The top blade does not have that characteristic "prop strike" bend. -- -- ET :-) "A common mistake people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools."---- Douglas Adams |

It does appear that the prop is feathered and none of the blades are bent
forward, which would be characteristic of a normal power setting prop strike. Jim "Seth Masia" wrote in message ... I agree. It also looks to me as if the prop is feathered. |

I agree with you, Bob, but look at the root of the prop blades. SOMETHING
forced those suckers into perpendicularity to the slipstream. Not that it matters; that airframe and engine are beer cans from the looks of it. Jim "Bob Gardner" wrote in message news Kinda hard to feather the prop on a piston single. |

You're right. It's a six-cylinder engine. They should have had plenty of power, unless they had none. Check the prop: does it look as if it was turning?

Bent backward, engine not developing power. |

So during a BFR, when the instructor pulls the throttle and tells me to set
up for a practice engine-out landing, and I pull the prop knob all the way back to reduce prop drag, I'm not feathering the prop? What am I doing?

In this case, no power. Feathered prop, or at least high pitch. Power-off
forced landing on the interstate at high density altitude. Ground speed at touchdown could have been 80mph, merging with traffic that often bogs to 50mph on the steep uphill at 10,000 feet. Pretty dicey but the passenger walked away and the pilot survived with a back injury. Good work. Seth "john smith" wrote in message ... "Seth Masia" wrote in message You're right.

What am I doing? Setting it to a high pitch but not feather. Does the prop stop turning? If not, it's not feathered, even if it does stop, in a single engine airplane it is probably not feathered.

What am I doing? A feathered prop has the blades go parallel with the forward motion of the plane. A single engine such as yours will not let the blades turn that much. You can reduce drag but not nearly as much as a full feathering prop. |

Okay, but look at the Picture 6 in the sequence at
http://www.thedenverchannel.com/news...57/detail.html Look carefully at the prop blades, then tell me whether this engine was making power at touchdown. Also, no fire. Fuel status? Selector closed?
