landing advice cache

OK. This sounds enough like what I think I'm trying to do to tweak the numbers a little and rehearse it a lot. I kiped it off rec.aviation.student:

Landing: The 'secret' to landing is learning not to try to land (so-to-speak). Here's a winning scenario:

First of all you have been very good about managing your airspeed in the various legs of the pattern. Remember a good landing is VERY much part of a good set-up.

So, there you are,,, abeam of the numbers--carb heat on, throttle to 1700, slowly bleed off the airspeed to the top of the white arc (the flap extension range), one notch of flaps, pitch for 75 knots [and trim to reduce yoke pressures].

Starting to turn to base, add the second notch of flaps in the turn (makes a difference) airspeed to 70 knots.

On final, third notch of flaps, airspeed 65 knots. If you are high on your VASI or PAPI, make a temporary reduction of power till the top of the VASI (for example) is starting to turn pinkish and then add back your 1500 RPM. Always remember power for altitude, pitch for airspeed, don't lower the nose to attempt to maintain the glide slope. Maintain airspeed, and manage altitude with power.

Over the threshold, throttle to idle, at this point look down the runway about the same distance you would if you were driving on the freeway at that speed (using the previous rule).

Round-out height (the point where you transition to flying level over the runway) is about a shoulder or waist length height above the runway (the mains, of course). So, there you are over the runway with power to idle. I don't want you to 'think about trying to land', 'TRY' to continue flying - that is, as you see sink apply a little back pressure for it, more sink,, more backpressure on the yoke. Remember keep trying to fly, you are not *trying* to land.... Soon you should find yourself in a nose high position touching down on the mains, just a split-second after there is a brief warble from the stall horn.

So, maintain a uniform, stabilized approach. Look down the runway the appropriate distance (if you look too close two things will happen; one, you'll be distracted by the ground rush AND also visually misjudge your height above the runway. Land by 'trying not to land' mindset can help you a lot. There is no rush,,, with power at idle (remember we reduced it to idle over the threshold) you WILL touch down,,, don't rush the flare,, you WILL land, beyond a doubt.

Once again, don't worry, it will all come to you and then you will be wondering why you couldn't do it before? ....

Hi Phil
Next time you go out take a felt tipped pen.
Sit on the runway on the numbers - look at the end of the runway - place
a dot on the windshield which aligns with the centre of the end of the
runway.

Go fly.

climb as high as you like - 4000 ft or 9000ft - the higher the better.

Pick a tree - aim for it with the dot on the windshield - at approach
speed. Fly down to it keeping it exactly under the dot and maintaining
approach speed (it is a REALLY good idea to flare before you reach the
tree :))

That exercise will quickly teach you how to maintain approach speed to
an exact point.
That exact point will eventually become your flare point over the runway.

After that, it's just a matter of learning the correct flare height.
Tip - you do that by watching the runway edges in your peripheral vision
- not by looking at the runway.

hope this helps

Give us a progress report,

Tony
