Thread drift, but: it seems to me that DFC makes an especially valuable contribution to these forums.

So anybody care to explain why he is the butt of so much childish, personal abuse?

Do you raise flap all in one go on a go-around?

Well in a C-42 that is what I've been told to teach. Could be to do with the climb rate of this butterfly. Done with the proviso that there is a +ve rate of climb indicated first. Nose just below horizon, wait for +ve rate of climb, raise all flap smoothly (not easy in a C-42 !) whilst keeping attitude, wait for climb speed, adopt climb attitude. Seems to work fairly well.

I find base leg the most important leg, get the base right and the final will be set up for you.
So, abeam the threshold on downwind,
reduce pwr,
hold altitued,
flaps to 20' once in the white arc,
70kts, trim. (we're in a nice 500'/min descent)
Now we turn base with 20 degrees of flap at 70kts. We can now assess our distance from the rwy. Maintain 70kts ALL thru the base leg allows us to be at that magic 600' before we turn final.
Example - If we are low mid base, add pwr to reduce the RoD, then we turn final at the correct height.
Now we turn on final still with 20 deg. flap at 70kts. We can add more flap as req.
This method gives us all the base leg to assess our options to set up for final, this reduces the workload (on the base leg) of more flap and airspeed changes & trimming, our objective here is to be perfectly set up for the turn on to final.
Now on final we are in a perfect approach pos'n, giving us the best chance to bring it home safely.
Works for me:)

2211,

I was taught the same procedure during my PPL. Everything worked out wonderfully until the day I had to fly to a busy airport and tower asked me to extend base. I can't remember how I adjusted my pattern then, but I do remember the feeling I had. I certainly didn't like it.
To learn procedures is a great thing, but only to a certain extend. It is also important to have an understanding on what happens with each procedure and each change (whether it is the flaps, the gears, the pattern or the winds).

See what you started Wicker Man! Very entertaining repart'e gentlemen.
