Unhappy Q' for 747 Classic driver

Somebody can help me with this,
at the phase retraction of flaps,
as we know in EFIS there will appear
in the speed trend.My question is
in the conventional how we rely on?
Thank's in advance.

To expand on CCA,
Bugs for first flap retraction speed and min manoeuvre clean. In between just add 20 kts to FFR for next flap retraction, 20 kts to that for the next and so on. ie for a F20 t/o, go F10 @ Vffr, F5 @ Vffr+20, F1 @ Vffr+40 (F5 +20) and F0 @ Vmin man.

Thank's for dropped by,
but I have one last question,
when we do the go-around,how many
degrees nose-up the attitude is?

Thank's and all the best.

If a landing is rejected very close to the ground and aft fuselage ground contact is a factor, initial go-round attitude should be limitted to 8 degrees. Once well clear, a 12 degree attitude can be set.

Pressing the go-round switches on an approach will result in the flight director displaying a 12 degree nose-up attitude.
