silly question on best glide speed?

There's the other point: isn't glide range extended in a 172 if the prop isn't windmiling? It is in any aircraft. Stefan |

There's the other point: isn't glide range extended in a 172 if the
prop isn't windmiling? Remember that picture in the different aviation rags several years ago of the Mooney with the feathered prop? Anyone remember what the add was for? |

There are some serious divisions over whether to stop a prop or not to get more range after an engine failure. When we stopped the prop on the 150, the airplane's attitude was more nose-down to maintain the same glide speed, and the rate of descent was higher. The theory here is that the much higher angle of attack on the prop blades when stopped causes more drag that if it's windmilling. Dan |

Empirical experiments show that, if you're lower than about 6,000' above your target landing point, you're better off trimming for best glide and letting it windmill.
