Well, ultimately you will get the best rate of climb clean after you have reached best limb speed, of course, but it's not al that significant at the begining unless you have a big obstacle problem off in the distance, so you're right, best flap position is usually around 20 or 15 or whatever is handy! Bertie An old rule-of-thumb I remember has it that aligning the flap with a down aileron gives you the best (most lift) flap position (assuming, i presume, that the ailerons deflect to maximum effectiveness=lift) Never heard it but it sounds like a good bush piloty sort of thing to do. Bertie - Hide quoted text - - Show quoted text -- Hide quoted text - - Show quoted text - Hence the reason why some of us fly planes that have flaperons instead of flaps/ailerons.. Eh,OK. Bertie |

Bertie Did you read "Nobody believed that we walked away" that I posted about Bud Warrens crash near here in Houston? I probably should have used a different title but that is how the newspaper article in paper was headed. Good Pilot and very lucky. Big John |

My flight instructor, a former drug-smuggler, taught me that very technique. The most lift is always gained with the most flaps. I try to shy away from the use of the word "always". There are some aircraft that use flaps for their induced drag. An example is a glider with large span 90 degree flaps. As an owner of such a craft I can testify that increased lift is not associated with flap setting greater then 40 degrees. Setting beyond 45 definitely exist only for the drag they create.

Even if true, you sometimes end up picking up drag faster than increased lift at extreme flap settings, depending on the aircraft. |

On your typical Cessna 152, 172, 182 206, etc the most lift for the least drag is approx 20 degrees. Flaps at 40 degrees gives you the most lift but also more drag than at 20 degrees. Just depends on what you're trying to accomplish. The first 20 years of Bonanza production there wasn't a flap indicator in the aircraft, don't have one in mine. The factory put a stripe that you could line up with the trailing edge of the wing to get 20 degrees. Those disappear with the first paint job. |
