Not analogous . . . ^^^^^

IMHO! Gotta love the aiplane issue! "SORRY!!!" when landing and you want to slow down, you use flaps to bleed off speed, you lower two trim tabs, built for one purpose!!! slowing to a managable landing speed. IF YOU! use flaps on takeoff, you will have a handfull getting off the ground and may NOT make the end of runway. Lots of power needed to counteract drag from flaps or trim tabs Only makes sence!

Umm, flaps are used to increase lift.

Flaps increase lift at the expense of energy. That energy expense- whether it be airspeed or engine thrust- is convenient on landing, but is less convenient for taking off, although still partially used (as a margin of safety) to become airborne.

QC said : Not analogous . . .

What he said...

I still say try it and see if you get the results you require.

So it looks like i gotta grab a cold one and borrow a gps and settle down for a day of harassing the fish. *sigh* just got her outta storage and noticed the floor's soft in one spot *reads oopss' post and shudders*

It's a tough lot and it takes a real man all day, but someone's got to do it...

well as long as she who must be obeyed is happy then im good


on the upside I think the ice is out enough so i can go after a pike or two..... *ideas begin to form*

Err...Well, that'll teach me to ignore a thread I posted on for a couple of days. My reference to the B737 had nothing to do with flaps. I was refering to the appearance of one classic design being retrofitted with something else. See it, waaaay out there at the end of the wing? The appearance probably appeals to some, probably is hated by others... I should hasten to point out that in no way do I think wing extensions on aircraft accomplish the same thing as $30 hydrofoils on outdrives...

Anyway, I apologize as I've obviously just muddled things terribly and really should try to keep my discussion of floating tin well seperate from the flying kind.

Finally, although you did completely lose me with your description of how to configure an aircraft for landing...application of flap on takeoff -type depending - is done all the time

Re: Do these work???

I can tell you this!! the more flaps you use, the more power you need to keep a stable airspeed!!

Re: Do these work???

you get more lift at a slower speed

This is true for both trim tabs and hydrofoils . . .

y
NOT AWAYS GOOD!!!" to get airborn at 40 knots when you need 60 knots for safe airspeed. { WILL!! test your training. }

There are very few situations with a boat that I would rather dig a hole than be on plane . . . Once in a while I want my bow almost uncomfortably high, but even then I like the ability to adjust a degree or two.

Now that this is an aircraft forum, I thought I'd trow out a thought. Every aircraft is different when it comes to flap setting for take-off and landing. the majority of aircraft use a low setting flap setting for take-off. It increases lift but increases drag as well. Upon take-off, you reach your rotate speed (Vr) and pull back on the column. After you start your climb (positive rate) you will call for gear up and then flaps up. Depending on the terrain and the airport, will depend on when the pilot in command calls for flaps up. Some aircraft have slats as well. Again, these increase lift and drag.

the advantage of flaps is to create more lift at a slower speed, reducing landing and take-off distances.

Hmmm, the take-off flap settings for the B767-200 are 1,5,15 or 20. The MD-11 takeoff flap settings is from 10 deg to 25 degrees, changeable to 1 deg. (using a dial-a-flap wheel). For the Deflected Aileron option, a discrete Flap 28 is available for takeoff in addition. Typical flap setting is 15 degrees for takeoff. A detent at 28, 35 and 50 is available with 35 and 50 used for landing.

The 777-200 flap settings detents are 1, 5, 15, 20, 25, 30. Typical takeoff flap settings are 5, 20 and 25.

Conditions, runway lengths, manufacturer and company procedures all determine various flap settings for take-off and landing.

I don't have space to store parachutes on my boat.
