Flight Model Errors

[Joe L]

Gradually pull the manifold 1" of a time from cruise

I am ashamed to admit, but it has been so long since I had RW time in a 182 that I forgot what I was taught. In sim I have used 1" per minute, I have heard 1" every 2 minutes, what do you use Geofa? Also, is shock cooling less of an issue below a certain MP, where you may be on or off once in the pattern, etc?Thank you for any insight to help my rusty brain fly realistically.Joe

I have issues slowing this thing down. If I'm flying at 170 kias, and cut the throttle, it takes about 3 miles to slow to 120... is that right?

LOL just hit full flaps. It is like throwing out full wing spoilers, reverse thrust, full flaps, slats, landing gear, and opening all doors at the same time.Just kidding... maybe... :( Where is a Carenado patch? I sure hope there is one coming soon.

Joe-shock cooling is as much debated as is whether one needs to reduce power at 1000 ft. agl on takeoff. I don't know if I time it but 1" every 1 minute sounds right to me. However-a few weeks ago in fairly heavy turbulence I was going from 15" to 23" back and forth just to maintain manuevering speed-so much for 1 minute throttle changes lol. What I really go for in all phases is to make power changes so smooth and gradual that a passenger doesn't even know I did it-and if that helps shock cooling/engine life so be it.With the pitch settled by kikiwat I am pretty happy with the flight model-except it should be able to lift off lower than around 90 knts which is what it seems to do now....and yes they gain airspeed rapidly when you push the nose over. When I go downhill I push the nose over for a 500 fpm descent and then gradually keep pulling the power to keep right next to the yellow-unless of course it is rough air. Another case where the reduction will be more than 1" per minute.

As for approaches-do it by the numbers. Gradually pull the manifold 1" of a time from cruise so that when you get into the pattern or the downwind/vectors for the approach you are at 17" in the summer and 15" in the winter. Leave the prop at cruise settings. This should take you to the top of the flap speed. When intercepting the glidslope-merely put the gear down-that will give you a 500 fpm descent-you may have to retrim a little. Some use flaps at this point-I prefer not to. When you have the runway made, drop the flaps and slow her down to 90<edit> ( whoops-my plane was in mph so aprrox. 75 knts)-prop full in.

Thanks for the numbers! I like to know what to do exactly. :( I will give it a try this way today.
