Sorry...enlighten me then...
Apologies for my ignorance again, I have now taken the time to find out exactly what triggers it: (essentially BA's way of enforcing SOPs)
a) Event Detection
This is a selection event types detected by BAs SESMA program:
Abandoned takeoff
Altitude deviation
Abnormal pitch landing (high)
Approach speed high within 90 secs of T/D
Climb out speed low 400 ft to 1500 ft AAL
High rate of descent below 2000 ft AGL
Deep landing
Land flap not in position below 500 ft AAL
Deviation above glidepath below 600 ft AAL
Mmo exceedence
Early flap change after T/0
Pitch rate high on takeoff
Exceedence of flap/slat altitude
Reduced flap landing
Excessive bank above 500 ft AAL
Reduced tail clearance
Excessive pitch attitude
Speedbrake on approach below 1000 ft AAL
Flap placard speed exceedence
Stick shake
Go around from below 1000 ft
Tail strike GPWS windshear warning
WAS resolution advisory
High energy at 1000 ft
Unstick speed low
High normal acceleration at landing- Vmo exceedence
