B737 late goaround

Just read the SQ report at MUN.

B737ng, in theory with reverse thrust not selected you can still touch down, apply max thrust, sod levers down, wait 3secs for auto brakes to cancel and off you go??

rotate at 15degrees with spd above vref In the window

Pin Head is probably referring to this report:

I thought it was standard at 73 operators that a go around is always considered possible until reverse thrust is selected?

Yes, once the thrust levers come are advanced from idle the auto speed brake retracts and the autobrake disengages. The autotrottle should remain armed (obviously if you haven’t disconnected during the approach) however 2 seconds at idle once on the ground is the point where it should disconnect itself. Press TOGA and rotate as normal when accelerating through VREF. Call for flaps 15 and away you go. Works a treat

Yep, can do it in Boeing and Airbus and in fact our Airline has trained just that type of thing for near on 15 years now. We call it a rejected Landing.....

Ok..

Thought it was 3 secs before the auto brakes kicks out?

Can you take flaps 15 in the transition i.e. Gnd to air, any issue with flap retraction on climb rate in the initial climb away?

Please don't rotate to 15degrees, you will hit the tail.

Of course you can go around after touchdown prior to reverser deployment, its simple, all you do is advance the thrust, you don't need max (dependent on runway length I suppose) and call "go around flap 15". PM retracts to flap 15 and you rotate normally very soon thereafter as you pass your Vapp. Job done.

Ok. At what unbugged speed will you elect to rotate?

15 is only when you fly off.
if you get lucky and get to 15 before lift off, you will take the runway paint with you.

I've personally witness a very smart training captain call rotate way pass V1.
Why ?
Well the newbie on the right hand seat yank the plane off the runway and went straight to 18 degrees as commanded by FD.
Did we get tail trike ? Nope..... the moment the right seat warmer yank back on the yoke, the plane jump into sky right away.

Vref Flaps 30 (and Vref Flaps 40+5) = V2 Flaps 15

In case of a rejected landing, just press TOGA, call "Go-Around Flaps 15 - Set Go-Around Thrust", select Flaps 15 (Pilot Monitoring) and rotate SLOWLY (to avoid a tailstrike) at Vref 30/40.
Aim for 14-15° Attitude and follow standard go-around procedures.

You can refer to the Touch and Go procedures in the FCTM: "At Vref 30/40 call "ROTATE""

I've always kept the rotation soft until I hear the click over my head and then continued on to 15'. NEVER before that click!

Ditto. Seems to work well enough.

I appreciate that V2 F15 is F30 Vref however are we going to remember that in a potentially stressful high adrenaline situation? A go around after touchdown is very uncommon and in the run up to it there is likely to have been a rather abnormal occurrence so keep it simple. Click click, arm length worth of thrust, check it is above the min safe speed presented to you then fly it off. Once safely airbourne start changing the config.

TOGA disconnect with weight on wheels as you are now in land. Look at the 777 crash at Dubai. As shown, once there is weight on wheels, pressing TOGA has no effect, AT does not advance. Its all manual now.

so you are going to rotate with flaps 30 or 40? Not a good idea.

I'm not talking a touch and go training scenario... I'm talking an aborted landing which will be less a touch and go more a 'ah bollocks' click click, arm out, fly off (expect it will practically hover off than standard go around. Odds are by the time PM is moving the flap lever the aircraft will want to be getting airbourne again.

I've gone around from a second prior to the mains touching and after calling go around the aircraft made ground contact on the mains, accelerated then flew off with the nose fairly low. After calling gear up recalled 'go around, F15, set go around thrust' as it appears to have been missed in the 'excitment'.
