When you're cruising close to REC MAX in a 321 and it starts getting bumpy, is it best to just select speed to the middle of the window and take a possible overspeed? Or would you use speedbrakes to fight it until you can get out of it? It seems like using speedbrakes that high up would fire VLS up right into the red.

Are you a flight simmer? Otherwise I’m scared.

Anyone who decided to climb up to REC MAX has made some pretty significant mistakes long before any speed excursion.

Be scared. Sorry to offend you with my apparent stupidity.

My thought exercise is basically 340 is bumpy, 360 is reported smooth, and REC MAX is say 367. You go up where the window is small and start hitting some bumps.

My interpretation so far is the general consensus of the guys sitting to my left at my shop is they're cool flirting with REC MAX as long as its smooth.

Uh, DO NOT use speed brakes in the 'Bus up high, they DO NOT stow immediately and you will be coming down in a hurry.

I used to commute into SAN on AA 321s every week, it was kind of funny watching a heavy 321 come in on the LUCKI and try to make the speed/altitude restrictions at the same time and basically throw their hands up.
 
I just wanna know, given our current social & political environment, why this airplane still continues to call us “retards”?

That’s actually against Airbus recommended procedure.

Management of Overspeed Events in Cruise | Safety First

Overspeed Recovery Technique
The flight crew should apply the Overspeed Recovery technique if the aircraft exceeds Vmo/Mmo.
• Keep the autopilot and autothrust engaged.
- Use of the autopilot is meant to ensure vertical loads remain minimal. Autothrust
will reduce thrust to idle (if autothrust is not in use, manually position the thrust levers to idle).
• Use the speedbrakes
– The use of speedbrakes will reduce the VMAX exceedance and duration. Using
speedbrakes can help prevent reaching the speed threshold that causes High Speed Protection to activate and the autopilot to disconnect. [CAUTION – when operating at speeds greater than 315KTS/.75M and the autopilot engaged, speed brakes retraction from FULL to RET may take as long as 25 seconds]
● Ensure thrust is at idle

The problem is pilots are pilots and some numpty is going to treat the speedbrake lever like an off/on switch.

FL320 it is, he said as he gave a thumbs down or otherwise gestures for a descent.
