Can anyone tell us what the actual window is @ 410 for a CRJ-200 @ ISA and say, 70% of MTOW, or does everyone agree that it's at least 70 KIAS, what most on this thread are referring to as "a pin head"?
.
Vmo/Mmo for the CRJ 100/200/700/900 are all the same. BoilerUp got the shaker speed from the PCL 3701 accident report.
Doing the High speed stall demo in the sim I was shocked at how slow you get before the shaker actually goes off.
The limiting factor is not coffin corner (I'm not even sure why this is part of the discussion), the limit of the airplane is the amount of thrust (or lack there of) that the CF34 3a1/3b1 engines produce (especially at ISA +anything). It is engine limited not wing limited.
Now to answer the question. Min Holding at my company is 188 at F410 (36k and below) and that will protect you from low speed buffet at 1.4G.
Max safe Altitude Chart states you can go up to 410 at 37000lbs if at ISA or below (or if ISA +5, you need to weigh 34000 or less BOW is generally like 29k or something there abouts I think).
It is a rare day you are ever that empty to be able to get up there, but on a long ferry flight it is a possibility.
