AUTOPILOT –-------------- OFF
BOTH FLIGHT DIRECTORS -- OFF
VERTICAL SPEED –--------- ADJUST TO THE GREEN (promptly & smoothly
I don't know about the Airbus types but why the urgency to switch off the FD? It takes a finite time to click off the autopilot and get cracking on the avoidance and at least 2-3 seconds for the PF to lift a hand to switch off both FD. And even if you request the PNF to switch off both FD's that too takes a couple of seconds - and all for what? With only five seconds to act, switching off the FD is the least priority. No one in his right mind is going to follow FD gyrations during a TCAS RA and therefore the FD indications are simply disregarded until the danger is passed, then appropriate FD re-programming can take place. Perhaps the order of action should be autopilot off, vertical speed adjust to the green and finally both FD switches off.
