Flap config for touch & go

[Avman]

Humour me please chaps for when I'm playing pilot on my FS! What (final) flap config does one use for a touch-and-go in a B737-400? I presume the manoeuvre is performed with a reduced flap setting and higher speed, and that the configuration is maintained throughout flare and subsequent rotation.

I assume the 734 is similar to other boeings in that, certainly on the 757, during T & G's at base, you landed with normal land flap (F30) because, after all, it is the normal landing maneouvre you're practising.
After touchdown, the base trng capt would stand the thrust levers up to stow the speedbrakes, and move the flaps to 20, when the flaps got to 20, set t/o pwr and calls rotate for HP at pre determined Vr for the T&G. All the time making sure the HP's heels are firmly on the floor away from the brakes!

Thanks for the reply. Now that's interesting because I (as a layman of course) would have thought that the speed brakes would not be armed and that the time waiting for the flaps to travel could amount to quite a bit of runway being used up.

As rodent's rear says, and Vr is calculated for flap 20 in the 757 case, and even if the flaps are slow to run to 20 it will still be a safe speed.

On the 737, flap 30 or 40 landing, no autobrakes, no speed brakes and no reverse to be used, on the landing roll spool the engines to about 50% N1 and then position plaps to 15 with trim in the green, when flaps are 15 TOGA thrust and around 120kts rotate...

:ok: Many thanks Springbok449.
