What i do see from the accident report is that PF has reacted about 5 sec after the speed got below 135kt
We shouldn't have the same report since in mine the X axis is graduated in 2 sec increments. My reading shows that after the speed got below 130 kts you have 13 units before AP disconnect, meaning 26 seconds... How many Kts of deviation are tolerated on approach during a JAA IR test flight? The same graph shows 7 seconds below 110 Kts before AP disconnection. With no offense to the crew this seems to be a lot of time, especially when Vref was lost for over 20 secs.
