An elementary landing / braking doubt

flaps are used to change the shape of the airfoil.. allowing flight at
slower speed for approach and landing... lower speed on landing, less wear
and tear on the tires, less braking action required and less runway length
required. And with flaps, creating more drag, more power on approach is
normally required to fly a std glide path.

FWIW, my aircraft, standard approach configuration, leading edge slats, and
full flaps, approach speed was about 150knts depending on weight. A flaps
up, no slat approach was about 210knts.. again depending on weight of the
aircraft (how much fuel remaining).. and if the approach were carried
through to landing, would require double the runway and possible hot brake
fire. If no fire, a tear down of the braking system on each tire (8) would
be required to ensure no heat damage from high braking temperatures.

no flap approaches would be practiced, but to a missed approach.

Hi folks,

I've always seen spoilers and flaps being deployed fully upon landing.
While the reason for spoilers is straightforward, I haven't yet figured
why flaps are deployed too.

Isn't the landing roll the time when you'd be wanting all the load of
the craft to be on the main wheels, which is where the brakes are,
instead of creating lift whereby the load gets transferred onto the
wings and possibly lessening the braking effect? I know the plane would
be decelerating all the time with the engines throttled back fully and
even the forward thrust depolyed, perhaps, yet why create any lift
possibility at all? Wouldn't braking be more effective with no flaps
deployed? Or does the drag produced by the flaps compensate for the
lift?

I suspect I've missed something really fundamental )
