Like someone said earlier, we are pretty standardized in using 290/.65 in the EP/LR and 290/.60 in the XR. The XR's mgtow is about 53,000 lbs. If you takeoff off weighing about 50,000 lbs you will fall below the low speed buffet margin if you attempt to climb straight to FL370 at .60 mach (meaning you could potentially stall the airplane if you encountered a significant bank angle). Accelerating to .65-.70 mach once you get into the mid 30's usually prevents this problem. The same thing would undoubtedly happen in an LR or EP if you tried climbing it at .56-.60 at weights close to MGTOW.

You should have low speed buffet margin charts somewhere in your CFM or performance manuals. Keep the speed at or above what the chart specifies. Allowing the speed to accelerate to .65-.70 when you pass FL300 is a good policy when you're operating a heavily loaded EMB-145. That should keep you above the low speed buffet margin and free from the PLI in most scenarios.

Our FLC modes in the EP/ER/LR's are the same as yours, 270/.56, but they are rarely used. The XR FLC modes holds 290/.60, but VS is still used by most pilots because of the autopilot's erratic pitch corrections in FLC mode.

Hope things are going well for you at eagle, fly safe.
