If EVER there was an airplane that didn't float it would be an Arrow II. I
was fortunate enough to instruct in the entire Piper line for a couple of years (with Bob Gardner!) Except Bob went on to become rich and famous and I just had to fly for food.

I have not have problems with thermals making me float down the runway An airplane impervious to ground effect? Matt Barrow wrote: "Turbo Arrow" wrote in message ... I have 2 ways of flying my arrow, in the winter I come in with no flaps and summer I use full flaps because of the change in air density,if I used full flaps in the winter I would float sometimes More likely you would float during the summer from the thermals associated with ground heating. |

... "Turbo Arrow" wrote in message ... I have not have problems with thermals making me float down the runway An airplane impervious to ground effect? What does ground effect have to do with thermals? Nothing, that's what. |

I see its a 1971, is that an Arrow II ? Nope...'72 is the first year for the Arrow II. So, I have an Arrow 200B. Its a nice looking plane BTW Thanks.

![]() "john smith" wrote in message ... One of aviation's Rules of Thumb... an approximate best approach speed is found halfway between the top and bottom of the white arc. It's certainly never going to kill you, but it doesn't make any adjustments for being light (say 1 pilot, and minimal fuel) - which can make approx 13 knots difference to the ideal approach speed in the Arrow (and 10 knots difference to your dirty stall speed). Since I started calculating approach speeds I've been amazed at how the consistancy of my landings has improved - even 5 knots makes a difference. |

just a note, on decents, instead of reducign power to come down, you can just pull the prop back, it will cause more drag so you can decend but keep engine from shock cooling (BTW this is out of the manual) "pulling the prop back" increases drag? Do you mean pulling on the propeller control knob? How does that increase drag? Maybe you meant that it reduces power? Dave |

Do you mean pulling on the propeller control knob? How does that increase drag? Maybe you meant that it reduces power? Dave No, it doesn't necessarily reduce power. Typically it will increase the manifold pressure. If there is not a concomitant reduction in RPM the power will increase. However, you will likely move the prop away from the optimum pitch for the airspeed/RPM combination. This will reduce the effectiveness of the horsepower to thrust conversion that you use the propellor for. That means that more power will be required for the same thrust. This allows you to maintain the thrust selected for the desired descent while producing sufficient power to keep the cylinders warm and working. However, I would not recommend that technique for all engines, even if it would probably work alright for a geared engine. "pulling the prop back" implies to me that you are increasing the pitch of the prop. With the throttle setting unchanged this will result in a decrease in RPM and an increase in Manifold Pressure. This moves you closer to the detonation margin and could result in engine damage. The normal procedure for increasing the pitch of a controllable or constant speed prop is to reduce the throttle before increasing the pitch. With a controllable prop you control the pitch directly. With a constant speed prop you increase the pitch by reducing the RPM with the prop governor control. High manifold pressure and low RPM is comparable to starting off with your car in high gear. It lugs the engine. Highflyer Highflight Aviation Services Pinckneyville Airport ( PJY ) |

No, it doesn't necessarily reduce power. snipped good stuff about how to operate your engine No disagreement there. I was trying to give Turbo Arrow a way to get out of his assertion. Do you support Turbo Arrow's assertion that "pulling the prop back" increases drag? I didn't think so. Dave |
