Manoeuvering in response to TCAS RA
In cruise with autopilot engaged and RA suddenly occurs. Should you immediately disengage autopilot/autothrottle and flight director at same time immediately following the RA commands?
Or:
Leave automatics engaged and use CWS or select VS mode to follow RA commands?
What are the chances of a delay in making the right MCP selection and thus causing a close shave?
Or worse still, press the wrong autopilot selection buttons and the autopilot fails to climb/descend?
Or, to minimise any automatic pilot mode delay following the RA command, is it generally a safer bet to disengage the automatics and get cracking without delay manually?
