i can think of two separate CRJ routes off the top of my head that fly departures that 250 on initial climb will not get you proper terrain clearance. There are countless more than have speed restrictions that put you below 250 knots on initial climbout. youre right its pointless to debate the real aircraft performance because it will get the thread closed. A quick youtube search of a pilot in a REAL crj will prove you wrong lol. You can watch them climb out well below 210 knots. If you are really convinced there isnt a bug send me a message and I will record the next flight it happens for me and you can analyze exactly what I’ve done wrong.
Edit it literally is entirely pointless because the bug happens in all stages of climb, I.E. im flying 250 knots, I pass 10,000 and set 290 knots with throttles in climb power. The plane will accelerate passed 290 on very rare occasions. So its pointless to debate in that regard also.
