Of course remember to cool your engine before chopping the power to prevent or minimize shock cooling. Hey -- let's start a new endless thread! Can you shock-cool an engine in summer? If you start with the assumption that shock-cooling is a real phenomenon(?), just play with some numbers. Say a typical summer temp is 80 degF and winter is 30 degF, and your cylinders are typically at 350 degF. So the delta-T is 270 degF in summer and 320 degF in winter. The summer delta-T is about 85 percent of the winter delta-T. Not that much different. Before someone complains, yes, of course, my choice of numbers is arbitrary. You can pick different numbers and make it come out any way you like. Plug in the numbers you think are typical. DGB |

If you're prone to panic perhaps you should stick with you Ford Falcon. G You should never "forget" the blue lever. A power increase should always be mixture, prop, throttle. -- Dale L.

Again faster airplanes are going to have less total drag, both induced and parasitic than slower airplanes. I don't have numbers handy but a Bonanza or Mooney (or Baron) is going to glide better than an Arrow. Here's some numbers that I have handy. Cessna 152 can glide for 16 miles from 10000 feet. Cessna 208 (Caravan) can glide for 22 miles from 10000 feet. The 152 is doing 60 knots, the 'van is doing 96 kts. -- Dale L.

The only positive thing you can say about these glide characteristics is that it makes it easy to avoid wake turbulence by staying well above a normal glidepath. I do it all the time in my Johnson Rocket -- overhead approach at cruise; break over the numbers, slow to gear/flap speed (100 mph) in the turn (it will be at the correct speed at the 180 point); continue turning and land at the 360 point, on the numbers. I have done this with a T-34 and a Zlin 242 -- all to 3-point attitude "squeakers". When dirty, these planes have about a 3:1 glide ratio. The 360 overhead allows you to monitor standard traffic and keeps you in tight, so you can control your glide. -- Remove _'s from email address to talk to me. |

The only positive thing you can say about these glide characteristics is that it makes it easy to avoid wake turbulence by staying well above a normal glidepath. The really amazing thing is that many other planes have *worse* glide characteristics than our Cherokees. I've got a friend with a Swearingen SX-300, which is basically a rocket, with stubby little wings. He says when you chop the throttle you are landing NOW, coming down at something like 3000 fpm. Another friend just finished building his Glasair III, and he says his isn't much better. That's the price you pay for all that speed, I guess. I have landed a friend's SX-300 from the overhead also. Glide is about 100 kt, but you have complete control over the plane -- it does roll out for awhile, though. -- Remove _'s from email address to talk to me. |

If you're prone to panic perhaps you should stick with you Ford Falcon. G Well, okay, sure.... But the question really was: what are the consequences? Does it typically lug and die, or will it lug and lumber upward slowly, or do I get one of the above plus twist the crank, etc.??? Do I get away with it? None of the time? Most of the time? Once in while? |

In my Lake Renegade, if you are abeam the runway pavement, and if you *turn immediately* to the runway (forget base and final), you can make the pavement. Otherwise, you won't. On top of that, the flare happens very quickly, because of the rapid rate of descent. You can increase the airspeed to give you more time for the flare, but that of course steepens your descent angle even more. I've got a friend with a Swearingen SX-300, which is basically a rocket, with stubby little wings. He says when you chop the throttle you are landing NOW, coming down at something like 3000 fpm.
