SOP changes needed ?

I think that SOPs need to be changed in order to avoid the repeated crashes after go around. Crash sequence begins with the extreme uncontrolled nose up pitch angle which is spotted too late and overcontrol of the the nosedown correction resulting in extreme nose down dive at low altitude.

The SOP change attempting to break this chain is as follows:

At Take off at the Vr Speed the PNF announces "Rotate XX" (XX being number of degrees eg. Rotate 14).
So on take off it is just one word more added to SOPs.

At Go Around situation the PF announces his intentions with words "Go Aroud" and commands some configuration change eg : "Go Around Flaps 11" so the PNF knows what is going on and what is expected from him at that time.

The PNF then announces "Rotate XX" (Again the XX is number of degrees) and then continue as per present SOPs. The same words "Rotate XX" are used in both Take Off and Go Around.

This little addition to the existing SOPs would help fhe pilot flying focus attention on the relevant instrument indication pitch angle which is often neglected by pilots focusing too much attention at the Flight Director or IAS indication.Also the PNF would adjust his attention span to include the pitch angle.
This change would help to reach and maintain the approximate pitch angle required for the initial climb out.

Calling the required pitch on each take off would make it a habit to do the same at the moment of a go around when the aircraft is rotated from approach pitch to the approximate go around pitch angle.
